DistributionSt. Vincent (Antilles)

Type locality: "West Indies"; restricted to “St. Vincent” by Henderson 1997: 210  
TypesHolotype: BMNH 1946.1.1.50, male 
DiagnosisDiagnosis: Corallus cooki is most easily distinguished from other members of the C. hortulanus complex by its color pattern. It lacks the color variation (pale yellow, orange, red, many shades of brown) found in C. hortulanus and C. grenadensis. Likewise, the main element of the dorsal pattern is relatively constant, and it rarely occurs in populations outside of St. Vincent. The diamond-shape pattern characteristic of C. ruschenbergerii does not occur in this species. Corallus cooki is distinguishable from C. hortulanus by maximum number of dorsal scale rows: invariably less than 50 in C. cooki (39–48; x = 43.9 +/- 0.34) and almost always more than 50 in C. hortulanus (47– 63; x = 55.0 +/- 0.17; specimens with less than 50 occur occasionally in Guyana, Suriname, Bolivia, and Peru) [from HENDERSON 1997].
CommentDistribution: [Corallus enydris cooki] “Costa Rica to Colombia and Venezuela; Trinidad and Tobago; St. Vincent, Grenadines, and Grenada” according to SCHWARTZ & HENDERSON (1991) but restricted to St. Vincent by HENDERSON (1997).

Synonymy: C. cooki is nested within hortulanus and thus may be a synonym of the latter (Colston et al. 2013). 
EtymologyGray's description merely gives the name "Edw. Cooke, Esq." Beolens et al. 2011: 58 believe this to be Edward William C90ke (1811-1880), an English artist who was most famed as a marine painter.
