CF1487A8927F3D47FDB5FE672572FD0E.taxon	discussion	Remarks The specimen with code MNCN 20.04 / 00104 was dry preserved and deposited inside a glass and wood case for display. Thanks to the annotations in the logbook, it is known that it was exhibited in the “ Sala del Mar ” exhibition. It is interesting to note that on the labels used for the “ Sala del Mar ” exhibition, there was always an attempt to provide some non-scientific name or clarify something about the morphology of the specimen to make it more understandable for non-taxonomists, as in this case “ Cangrejo costero de la Isla de Francia ” (coastal crab from the Island of France [= Mauritius]). The appearance of the male with MNCN 20.04 / 00643 code, although is preserved in ethanol, indicates that at some point it was dry preserved. It is not explicitly written, but it is very likely that this specimen was also exhibited in “ Sala del Mar ”. In the specimen MNCN 20.04 / 00104, the technique of fixation for dry preservation and display aided by needles can be observed. Because of this, it has not been possible to manipulate it, and it has not been sexed in order to avoid damaging it. For identification see also Michel (1964) and Galil (1997).	en	Muñoz, Isabel, García-Raso, J. Enrique, Chillón, Begoña Sánchez, Cuesta, Jose A.

CF1487A8927A3D40FDB1FEB82494FD9E.taxon	discussion	Remarks All the specimens had the previous identification as Calappa tuberculata (Fabricius, 1787). The specimens MNCN 20.04 / 00117 and MNCN 20.04 / 00118 are dry preserved inside a glass and wood box. Both specimens were previously held by a large needle positioned through the centre of the carapace. The specimen MNCN 20.04 / 00118 has the shell cracked in half. There are still remnants of the old codes that were annotated on the specimen itself. Those codes correspond to the ones used for the catalogue published by San Miguel de la Cámara in 1910 (ACN 0287 / 001). The specimens MNCN 20.04 / 00618 are covered with fungi, a sign that at some point they lost the ethanol and were dried out.

CF1487A892643D5EFDD0F9AB25E1FAFF.taxon	discussion	Remarks Tumidodromia dormia is the largest known sponge crab (up to 200 mm cw), and inhabits shallow waters (McLay 2009). Only two ovigerous female specimens of this species have been captured (McLay 2009), and our specimen is a female, but due to its fragility, it is not convenient to manipulate the specimen, therefore it is not known if it is ovigerous or not. For identification see also Lewinsohn (1984) and McLay (2001, 2009).	en	Muñoz, Isabel, García-Raso, J. Enrique, Chillón, Begoña Sánchez, Cuesta, Jose A.

CF1487A892613D55FDBEFEDC2288FDEC.taxon	discussion	Remarks In Fig. 23 G, the text written by G. Nobili (1906) where he identifies the 3 specimens included in MNCN 20.04 / 03349 is provided. The specimen MNCN 20.04 / 00189 is a dry preserved specimen, which is not dated, but according to the MNCN archive, it already appeared in the catalogue from 1910, and its collector could be Guérin-Méneville, so it may have been collected around 1850. The specimen was identified as Menippe rumphii (Fabricius, 1798), a species from the waters of the Indian Ocean; however, after comparing it with specimens of M. rumphii (see Holthuis 1993; Vartak et al. 2015; Naderloo 2017; Al-Hindi 2019), we found that the first two anterolateral teeth of the carapace are prominent and rounded, as occurs in M. nodifrons, and not are in M. rumphii, which are mostly flattened. The origin of the MNCN 20.04 / 00189 specimen should be considered with caution. On many occasions, we cannot guarantee the provenance of some ancient specimens housed in the collection, as could be the case here However, all the dry specimens reviewed in this work and part of an exhibition at the MNCN, originate from the Indian Ocean, and this fact leads us to consider its origin as correct. This reidentification of the specimen as M. nodifrons provides the first record of this species not only in the Mauritian waters but also in East Africa and Indian Ocean. Menippe nodifrons is recorded from the Western and Eastern Atlantic, along the western African coast from Mauritania (Fransen 1991) to Angola and Cabo Verde Islands (Manning & Holthuis 1981). For identification, see also Nobili (1906) and for similar species Rathbun (1930), Capart (1951), Monod (1956), Holthuis (1993), Vartak et al.

Ryphila is a genus described by Galil (2009), when she established a new combination for Philyra scabriuscula as R. cancellus. There is some confusion regarding the position of P. scrabiuscula, as at present the validity of this name is still being considered, as read in DecaNet (2025), or GBIF (2024). This paper provides the first record of R. cancellus in Mauritian waters. For identification see also Galil (2009).	en	Muñoz, Isabel, García-Raso, J. Enrique, Chillón, Begoña Sánchez, Cuesta, Jose A.

CF1487A8925E3D65FDAEFCE52302F846.taxon	discussion	Remarks This specimen belonged to the exhibition of the Sala del Mar, being dry preserved inside a glass and wooden box, without retaining any old label. It is currently identified as Apiomithrax violaceus (A. Milne-Edwards, 1867), originating from the waters of the Cabo Verde Islands. However, this specimen is not A. violaceus, nor is there any species or genus with similar characteristics in the waters of West Africa. The specimen belongs to the species Tylocarcinus styx (Herbst, 1803) which has an Indo-Pacific distribution, as do all species of this genus. This led us to question whether the origin of this specimen was truly Cabo Verde, or perhaps it came from Indo-Pacific waters. In the current records and for many years now, the only data we can obtain about this specimen is that it comes from Cabo Verde, with no collector’s name or year of collection, and a comment where a number supposedly from a catalogue appears, but we have not been able to determine what it corresponds to. Reviewing the inventory files and catalogues of the historical collections of the MNCN, an inventory by San Miguel de la Cámara in 1911 (ACN 0248 / 005), was found, in which a specimen that could be our specimen appears. On page 22 of said catalogue (Fig. 45 C – D), a specimen with an almost crossed-out name appears, where “ Arctopsis Styx Herbst from Île de France (current Mauritius), collector Guérin ”, can be read, and just below this, the name Micropisa violacea from Cabo Verde (Fig. 45 D). We believe that the crossing out of the name, the accompanying date, and the arrangement of the data caused the confusion that has persisted to this day, leading to the assumption that this specimen was the species Micropisa violaceus (today labelled as Apiomithrax violaceus), and that it originated from the waters of Cabo Verde. Since that date in 1911 when San Miguel de la Cámara made his notes about these specimens, this specimen has been considered to originate from the waters of Cabo Verde. However, it is now demonstrated that this specimen comes from the waters of Mauritius and was collected by Guérin-Méneville in 1850. For identification, see also Sakai (1938), Griffin & Tranter (1986) and Poore & Ahyong (2023).	en	Muñoz, Isabel, García-Raso, J. Enrique, Chillón, Begoña Sánchez, Cuesta, Jose A.

CF1487A892393D1DFDF3F88F27BDFBB0.taxon	discussion	Remarks The specimen was previously identified as Actaea laevigatus, a species name combination that has not been found in literature and is possibly due to a misspelling. The key provided by Serène (1984) leads to Atergatis laevigatus A. Milne-Edwards, 1865 (cw / cl = 1.6 − 1.7) and A. obtusus (cw / cl = 1.5), since our specimen ratio is at 1.54. According to Serène, it would not be any of these two species. However, Takeda & Marumura (1997) published that the carapace proportions of the genus Atergatis varied with the size of the specimens; subsequently, Maenosono (2022) identified a specimen as A. obtusus with a ratio of 1.54. Takeda & Marumura (1997) also observed that A. laevigatus has a prominently projecting anterolateral margin (shoulder), whereas A. obtusus does not, as Takeda & Marumura (1997) named it “ sloping shoulder ”. Our specimen agrees with the sloping shoulder shape. Subsequent to Serène (1984), the species Atergatis interruptus Takeda & Marumura, 1997 was described, which in its description take its place between A. laevigatus and A. obtusus based on the proportions. However, the posteriolateral edge is interrupted, which does not occur in our specimen. This species has few records, and was previously recorded in Thailand, Vietnam, Philippines and Japan (A. Milne-Edwards 1865; Lai et al. 2011; Maenosono 2022). If the identification is confirmed in the future, this work would provide the first record of A. obtusus in waters of Mauritius, and extend the distribution range for this species. This new citation, far from its known distribution area, would not be exceptional, as many other species in the Indian Ocean have very broad distributions. However, due to all the previously mentioned points, it is possible that there are very closely related “ twin ” species that have not yet been described, and a molecular approach could solve heir taxonomic status. For identification, see also A. Milne-Edwards (1865), Serène, (1984), Takeda & Marumura (1997) and Maenosono (2022).	en	Muñoz, Isabel, García-Raso, J.

CF1487A892253D19FDB7FE8C236CFE94.taxon	discussion	Remarks This specimen is dry preserved and placed inside a glass and wooden case for exhibition. There is a hole in the centre of its carapace from having been pinned at some point. Possibly, this specimen was part of the “ Sala del Mar ” exhibition. It was identified as Herbstia rubra A. Milne-Edwards, 1869, and labeled as being from Cabo Verde. However, it turned out to be Pugettia producta (Randall, 1840), a species common in the Northeast Pacific, not the African Atlantic. Therefore, this is clearly a mix-up. Based on the available data analyzed, everything suggests that this specimen was likely collected during a Scientific Commission for the Pacific, held between 1862 and 1865, by order of Isabel II, Queen of Spain. As it is not a species native to African waters, it should not be included in this catalogue, but we have chosen to cite it as an “ additional specimen ” because mislabeling in ancient collections is not uncommon and because, by doing so, we highlight the challenges that can arise when studying ancient collections.	en	Muñoz, Isabel, García-Raso, J.
