338 BARBOUR: ZOOGEOGRAPHY. 



variation in the scale counts is shown by the following numbers taken from the 

 cotypes: — ventrals 201, subcaudal pairs (tail imperfect); ventrals 199, sub- 

 caudal pairs 127; ventrals 194, subcaudal pairs 125; ventrals 205, subcaudal 

 pairs 120; ventrals 205, subcaudal pairs (tail imperfect); ventrals 193, subcaudal 

 pairs 121. In every case the anal is divided. The range then may be expressed 

 as v. 193-205; subc. 120-127 pairs. 



Leimadophis ater (Gosse). 

 Gosse, Naturalist's sojourn in Jamaica, 1851, p. 228. Bahbotjr, Bull. M.C.Z, 1910, 52, p. 300. 



A snake which has been practically exterminated by the mongoose. It was 

 formerly abundant upon Jamaica, but has not been found at all by recent col- 

 lectors. 



Leimadophis callilaemus (Gosse). 



Gosse, Naturalist's sojourn in Jamaica, 1851, p. 384. Barbour, Bull. M. C. Z., 1910, 52, p. 300. 



Another species which, though it has become rare, has not yet been quite 

 extirpated by the mongoose. It is confined to Jamaica.

 Leimadophis andreae Reinhardt & Lutein. 



Reinhabdt & Lutken, Vid. meddel. nat. foren Kjobenh. for 1862, 1863, p. 214. Boulenger, Cat. 

 snakes Brit, mus., 1894, 2, p. 140. 



The rather complicated synonymy of this species seems to have been settled 

 satisfactorily by Boulenger. The species is confined to Cuba, and is represented 

 in the collection here by the specimens which were collected by F. Poey and which 

 served Garman for the types of his synonymous Dro?nicus cubensis (Proc. 

 Amer. philos. soc, 1887, 24, p. 280). Besides these we secured a series by fol- 

 lowing ploughs on the Soledad sugar estate, near Cienfuegos. This species 

 seems to spend much of its time burrowing under ground or hiding under stones. 



Leimadophis temporalis (Cope). 

 Cope, Proc. Acad. nat. sci. Phila., 1860, p. 370. Boulenger, Cat. snakes Brit, mus., 1894, 2, p. 143. 



A well defined and apparently very uncommon Cuban species. Garman 

 (Proc. Amer. philos. soc, 1887, 24, p. 281) believes that this is the species figured 

 by Jan as Dromicus nuntius. Boulenger, however, (loc. cit., p. 181) identifies the 

 latter species with Urotheca lateristriga, from Central America. Cope states that 

 the type is in this Museum. The only specimen is No. 297. This is beyond 

 doubt the typical specimen, although it bears no contemporary type label. 



I have never found this species in the parts of Cuba where I have collected.
