Rhabdosoma lineatum. 



Dumerll & Blbron, 1854, Erp. Gen., vii, 105, describe this species from 

 Java. There is no doubt that the specimens described below came from 

 Trinidad ; they were taken by the writer near Port of Spain. Prof. Jan 

 has already questioned the locality given by Dum. & Bibr., most likely 

 with reason. Prof. Cope tells me he also has noted the species from Trini- 

 dad. The individual variations are so great that we may yet have to in- 

 clude Jan's B. punctivittatuvi. 



Body stout, cylindrical ; head not distinct from neck, subconical, 

 slightly depressed; tail short, thick, pointed. Eye small, pupil round. 

 Crown-shields nine; internasals small, short ; prefrontals large, long, 

 narrow in front, broad behind, entering the orbit ; frontal subtriangular, 

 as broad as long, acute-angled between the parietals ; supraoculars small, 

 broad ; parietals large, wide ; nasals divided, nostril in the anterior half, 

 both anterior angles acute. Loreal widest in front, long ; entering the 

 orbit in one specimen, not fused with the anteorbital in another. Post- 

 orbitals two ; temporals 1 + 2, upper elongate. Labials eight, first small, 

 eighth large, fourth and fifth in orbit. Lower labials eight, fourth and 

 fifth largest ; submentals one pair, large, in contact each side with first 

 four lower labials, separated from the small nieutal by the first pair. 

 Scales smooth, broad, in fifteen rows. Anal entire. Ventrals 146, 136; 

 subcaudals thirteen pairs in one, eighteen in the other. Total length 8.5, 

 tail 0.5 inches. 



Color light reddish brown, puncticulate with brown. A median nar- 

 row streak of brown from the occiput, another on the upper edge of the 

 third and lower edge of the fourth, and another on the upper edge of the 

 first and lower edge of the second rows. Belly white (? red or yellowish 

 in life). Head darker, clouded. On one specimen the edges of the 

 scales are darker. 



LioPHis cobella L. ; Wagl. 



Trinidad. Rows 17 ; ventrals 157 ; anal bifid ; subcaudal 63 pairs. 

 Dromicus dumerilii. 

 Calamaria dumerilii Bibr. 

 Urotlieea dumerilii Bibr. 

 Rows 17 ; ventrals 153 ; anal bifid. The specimen agrees well with the 

 description except in the number of ventrals, which was 138, twenty-five 

 less than in the present. 



Dromicus cursor LaC. 



Martinique. Scales in seventeen rows, with one pore. Ventrals 194, 

 191, 191, 186, 185. Anal bifid. Subcaudals 106, 103, 101 pairs. 



The name cursor was given to this species by LaCepede in 1789, Quad. 

 Ovip. et Serp., ii, pp. 96, 380, PL xiv, f. 3. Doundorft' from this figure and 

 description renamed iifugitiviis in 1798, Zool. Beytr., iii, 206.
