CommentSynonymy: Chippaux, 1986, has suggested that C. enydris is monotypic. STULL (1935) placed Boa grenadensis in synonymy with B. enydris cooki (= Corallus cookii). C. cooki is nested within hortulanus and thus may be a synonym of the latter (Colston et al. 2013).

Diagnosis.—Corallus grenadensis is distinguished from C. hortulanus by maximum rows of dorsal scales (37–46, x = 41.0 +/- 0.12 in grenadensis vs. 47–63, x = 55.0 +/- 0.17 in hortulanus). The primary spade-like element of the dorsal pattern occasionally occurs on the mainland (primarily the Guianas and northeastern Brazil), but not on St. Vincent (C. cooki). The rhomb pattern typical of C. ruschenbergerii does not occur in C. grenadensis [from HENDERSON 1997].
