Genus Grayia Günther, 1858 View in CoL
Grayia caesar ( Günther, 1863) View in CoL CAESAR’S AFRICAN WATER SNAKE
Xenurophis caesar Günther 1863:357 View in CoL , pl. 6, fig. c. Holotype: BMNH 1946.1 .6.38 (formerly BMNH 1843.1.10.7) (collector W. Raddon). Type locality: “Fernando Pó” [= Bioko], Equatorial Guinea.
Grayia caesar View in CoL : Chippaux (2006:94), Chirio and LeBreton (2007:432), Wallach et al. (2014:310).
Global conservation status (IUCN): Not
Evaluated.
Global distribution: The species is known from Cameroon, Central African to
Democratic Republic of the Congo.
Ocurrences in Angola (Map 346): The species has been recorded from the Cabinda enclave. Cabinda: “Mouth of the Loango”
[-5.15000, 12.16667] ( Boulenger 1894:288).
Taxonomic and distributional notes:
This species was only recorded from Angola by
Boulenger (1894), this record could correspond to Grayia smithii ( Leach, 1818) , however, the extralimital records of G. caesar ( Chippaux
2006; Chirio and LeBreton 2007; Wallach et al.
2014) are consistent with its occurrence in the
Cabinda enclave. MAP 346. Distribution of Grayia caesar in Angola.

Grayia smythii ( Leach, 1818) View in CoL SMYTH’S AFRICAN WATER SNAKE

Global conservation status (IUCN): Not Evaluated.
Global distribution: The species is known from Lake Victoria west to Senegal, north into the southern Sudan and southwest to northern Angola.
Ocurrences in Angola (Map 348): The species occurs in the northern Angola. Cabinda: “Mouth of the Loango” [-5.15000, 12.16667] ( Boulenger 1894:287). Lunda Norte: “Dundo” [-7.36667, 20.83333] ( Laurent 1964a:102); “Barrage de la Luachimo” [-7.38333, 20.85000] ( Thys van den Audenaerde 1966:34); “Dundo, rivière Luachimo” [-7.38333, 20.85000] ( Laurent 1950a:8).

Taxonomic and distributional notes: Two possible specimens are noted as being the type
(see above). In the BMNH registers both (under their 1946 reregistration numbers) are listed as being a type of C. smythii or G. silurophaga (or Grayia smithii or G. silurophaga ). Grayia silurophaga Günther, 1858 is a junior subjective synonym of G. smythii ( Leach, 1818) .
According to Boulenger (1894), Günther probably inadvertently included the type of Leach’s species in the type series of his own new species. Although Wallach et al. (2014) considered Boulenger’s (1894) comments as constituting a lectotype designation, it seems more probable that only a single specimen was present from the collection made by Cranch.
However, it is impossible to determine this from the description itself. The correct version of the specific epithet of this species has been questioned. Although many authors have used
G. smithii , the description employs Smythii .
Although there is compelling evidence from the original publication (several other new species of animals are named with the MAP 348. Distribution of Grayia smythii in Angola.
patronym Smithii View in CoL ) that the species was probably named after Professor Christen Smith, who accompanied the expedition (see Laurent 1956), Wallach et al. (2014) are correct that Article 32.5 of the International Code of Zoological Nomenclature prohibits an emendation under the present circumstances.

Grayia tholloni View in CoL : Laurent (1954a:44), Loveridge (1957:267), Broadley (1983:22), Broadley et al. (2003:182), Spawls et al. (2004:338), Broadley et al. (2003:182), Chippaux (2006:95), Trapé and Mané (2006:105), Chirio and LeBreton (2007:438), Wallach et al. (2014:311).
