            <p> Rhinella marina</p>
            <p> is a large toad identified mainly by all cranial crests well developed; head wider than long; snout rounded in dorsal view; parotoid glands longer than wide, with triangular to ovoid shape, with indistinct borders; and dorsal skin covered by irregularly scattered warts (Easteal 1986; Kwet et al. 2006; Rodriguez &amp; Duellman 1994). Etymologically the specific name  marina is the Latin word for “of the sea”. Linnaeus described  R. marina based on the description provided by Seba (1734). Seba, or someone who collected the toad, mistakenly believe that the species could be found on land and sea: “terra marique vivere patet” which means “is free to live on land and in the sea” (Easteal 1986). </p>
            <p> When compared, the illustration (Fig. 1) and description of  Rana marina (Seba, 1734) and the specimen ZISP 256 (Fig. 3) have many similarities. ZISP 256, as indicated in the first line of the tabula septuagesima et sexta: “ Num. I.  Rana, Marina, Americana , rara; mas. ” (Seba, 1734), corresponds to a male. We confirmed this designation based on external characteristics outlined by Lee (2001) and Kelehear &amp; Shine (2019), without resorting to incisions or forced mouth opening, to examine gonads or vocal slits respectively, given the age and relevance of this specimen. Firstly, we evaluated the robustness of the forearms (Fig. 4), assessing this condition by calculating the ratio of forearm width (at the midpoint of its length) to forearm length (FAR) of ZISP 256. We then compared this ratio with that of a female specimen (RMNH41769) of similar size (SVL of 129.78 mm) from Paramaribo, Suriname, the suggested most likely locality of the holotype (see discussion below), housed at the Nationaal Natuurhistorisch Museum, Leiden, The Netherlands. Our findings indicated that forearm width in ZISP 256 (19.6 mm) accounted for 57% of the FAR, while in the female was 34% (forearm width = 11.32 mm; FAR = 33.16 mm), supporting the more robust condition of ZISP 256. Secondly, there is a noticeable progressive shift in color from dark brown in the throat to light brown in the venter (Fig. 3C). It appears that the originally black throat turned brown due to preservation conditions. Thirdly, a dorsal colouration leaning more towards yellow than brown, commonly found in females (Fig. 3A). And finally, presence of nuptial pads, identified in ZISP 256 by a different color found on the thumb and adjacent fingers (Fig. 4A). </p>
            <p>Also, as described and shown in the illustration by Seba (1734), ZISP 256 presents large and small tubercles along the body (dorsally), except on the head. In both, illustration and ZISP 256, the head shape is rounded in dorsal view (Fig. 3D); cranial crests are present and well developed (Fig. 3D–E); parotoid glands have ovoid shape (Fig. 3E); with dark patches arranged in the form of broad, interrupted dorsolateral stripes, parallel, well-marked, with the presence of tubercles of different sizes that arise in the anterior region of the parotoid glands and end on each side of the cloaca, which appears to be an effect of the status of preservation of ZISP 256 (Fig. 3A); and interdigital webbing present on hindlimbs (Fig. 3G).</p>
            <p>However, different from the illustration, ZISP 256 is fixed and conserved with arms and legs folded (Fig. 3C). In the description of Seba (1734) (tabula septuagesima et sexta): “ Ubi pedes ejus antici, &amp; postici, extensi lunt, longitudine dimidium cubitum excedit; neque tamen extendi satis nune potest, quia exsiccata est...” in literal translation means: “When its forelegs and hindlegs are stretched out, they exceed half an ell in length; fact is it cannot be extended, because it is dried out”. It appears that the description and illustration was done before the specimens was dried out. Most likely the specimen was described still fresh and perhaps where it was collected as might be suggested by the text: “ Oculi grandes, lucidi” which means: “Eyes large, bright”.</p>
            <p>Also, the size ratio of hands and feet differs between ZISP 256 and the illustration. To facilitate comparison, we show ratios of hand length (HAL) to forearm length (FAR) and foot length (FL) to tibia length (TIL) from ZISP 256 and the illustration. The measurements of ZISP 256 are provided below with their redescription, while those for the illustration were estimated, in pixels, with the help of the ImageJ software v1.5. (Schneider et al. 2012) based on an illustration from black-and-white copy of Seba (1734) available at &lt;https://www.biodiversitylibrary.org/&gt;. ZISP 256 (HAL/FAR = 0.96) has hands slightly larger than the illustration (HAL/FAR = 0.90) and feet (FL/TIL = 0.94) 30% larger than the illustration (FL/TIL = 0.57). The limb digits also differ in their relative length of the fingers I &lt;II &lt;IV &lt;III in the illustration (Fig. 2) and II &lt;IV &lt;I &lt;III in ZISP 256 (Fig. 3F–G) and toes I &lt;V &lt;II/IV &lt;III in the illustration (Fig. 2) and I &lt;II &lt;V &lt;III &lt;IV in ZISP 256 (Fig. 3F–G). Furthermore, the termination of the digits also differs. In the illustration (Fig. 2), digits are rounded and widened, resembling adhesive disc, whereas in ZISP 256 (Fig. 3F–G), digits are rounded but not widened. These differences may stem from the illustrator’s interpretation, potentially influenced by folded arms and legs condition observed in ZISP 256.</p>
            <p>Comparisons and diagnoses recovered from illustrations found in Seba’s book can be a challenging task (e.g., Lavilla et al. 2013). Initially books were sold black-and-white, and thus, the quality of the representation of the drawings prevents an unambiguous comparison to the high-resolution photos we presented here. It is known that copies of Seba’s books were colored individually by many illustrators, perhaps at the own expense of the buyers (Müsch 2001). Thus, different quality of drawings and paintings can be found among books printed (see Fig. 1). Maybe the illustrators adapted the colors by comparing to other known species, but not necessarily the actual colors, since it is most likely they did not access the specimens (Bauer 2012; Müsch 2001). Perhaps birds and mammals attracted more the attention of illustrators, since the drawings found in Seba’s books of these species seem to be more faithful to reality. Although we suggest that the comparison of coloration between photos and illustrations should be done with care, it appears that it is somehow close to the drawing we represent here. We only note that there is a slight difference in coloration between ZISP 256 and the illustration, as the beige patterns in some regions of the body (e.g., irregular beige mid-dorsal area, legs and, glands) could indicate a rupture of the integument due to preservation or friction with the glass jar.</p>

            <p> The type locality of Seba’s specimens also has been subject of historical discussion (see the case of  Rana margaritifera Laurenti, 1768 in Lavilla et al. 2013).  The type locality of  R. marina was originally indicated as originating from  America (Linnaeus 1758; Seba 1734), but it was restricted to Suriname by Müller &amp; Hellmich (1936) and Schmidt (1941), as apparently this is the most probable area of for many specimens of  Seba’s collections.  Based on information indicated by Seba (1734), we suggested the coastal area in Suriname, in particular, Paramaribo as the type locality of the species.  Seba visited incoming ships in  Amsterdam and bought specimens from many parts of the world (Boeseman 1970).  As in the early 18 th century only the area around Paramaribo, Suriname, was settled, it is most likely that  Seba’s specimen came from there (Hoogmoed 1973). Duellman &amp; Wiens (1993) designated the neotype of  Scinax ruber (Laurenti, 1768) based on the same assumption. Also, as stated by Easteal (1986), the specific name  marina was mistakenly used to indicated that the species could live on land and sea. Thus, it is not unlikely that we could assume that the type could have been collected in an area close to the coast. Also being an old town and a departure point (i.e., port), removal of specimens for trade was easier. However, this is only a suggestion and more detailed information should be evaluated in future studies, perhaps by inspecting documents of diaries, trades, and ship routes of that date. </p>
            <p> The finding reported herein significantly contributes to nomenclature of the species  Rhinella marina as well as the group and clade it was nested and also named (Pereyra et al. 2021). Although there are still many unresolved gaps regarding the diversity and history of names related to the  R. marina group, such as proper diagnoses for many species of the group [see Acevedo et al. (2016) and Pereyra et al. (2021)], found type specimens (e.g.,  Bufo diptychus Cope, 1862 : Lavilla &amp; Brusquetti 2018), and description of candidate species (Pereyra et al. 2021), we consider that the redescription of the holotype of the oldest species of the group can clarify and improve its understanding. </p>
