ANOLIS RICHARDII, D. & B. Anolis griseus, Garm. 1. c. p. 36. 6. IGUANA TUBERCULATA, Laur. 7. AMEIVA SURINAMENSIS, Laur. Ameiva aquilina, Garm. 1. c. p. 3. 8. MABUIA AURATA, Schn. Mabuia cenea, Gray, Garman. Two specimens. These have the supranasals separate, as described by Garman; but these shields are in contact with each other in the type specimen of M. cenea from St. Vincent. The keels on the scales almost obsolete. 9- XlPHOSOMA HORTULANUM, L. 10. COLUBER BODDAERTII, Sentz. Ventrals 192, 200; subcaudals 92, 120. 11. HERPETODRYAS CARINATUS, L., var. VINCENTI. More slender than the type. Ventrals 168, 166; subcaudals 155, 148. Three postoculars; temporals 1+2; three labials entering the eye. Blackish brown or black above ; upper lip and gular region yellowish ; belly plumbeous or blackish. Continental specimens of this species have usually 145-160 ventrals, 125-140 subcaudals, and two postoculars. However, as we have in the British Museum a specimen from Venezuela with 164 ventrals and 171 subcaudals which is otherwise not separable from H. carinatus, I must regard the St. Vincent specimens as referable to a variety rather than to a distinct species. Specimens from Guadeloupe and Trinidad do not differ from the typical H. carinatus. Five species of Herpetodryas may be distinguished, as shown by the following synopsis :- I. Scales in 12 rows; anal usually divided. Four or more rows of scales keeled 1. sexcarinatus, Wagl. Scales smooth, or only the two middle rows keeled 2. carinatus, L. II. Scales in 10 rows. Anal entire; scales smooth, or only the two middle rows keeled 3. fuscus, L. Anal divided; scales smooth.. 4. melas, Cope. Anal divided ; scales keeled 5. grandisquamis, Ptrs. 12. HYLODES MARTINICENSIS, Tsch. 13. LEPTODACTYLUS CALIGINOSUS, Gir. Leplodactylus validus, Garm. 1. c. p. 14. |
