340 BARBOUR: ZOOGEOGRAPHY. 



Leimadophis juliae (Cope). 

 Cope, Proc. Amer. philos. soc, 1879, 18, p. 274. Boulenger, Cat. snakes Brit, mus., 1894, 2, p. 139. 



A fine species, which has been found abundantly upon Dominica. 



The difference in color which Garman has mentioned (Proc. Amer. phil. 

 soc, 1887, 24, p. 281) is very conspicuous in specimens from this island and 

 Marie Galante, and there seems to be no reason why, if this is found to be the 

 case in large series, the Marie Galante species should not be considered a valid 

 race. It may be called 



Leimadophis mariae, sp. nov. 



The types are No. 6,138, M. C. Z. The characters have already been 

 given by Garman. 



Leimadophis perfuscus (Cope). 

 Cope, Proe. Acad. nat. sci. Phila., 1862, p. 77. Boulenger, Cat. snakes Brit, mus., 1894, 2, p. 133. 



A well-defined species confined to Barbados. 



Leimadophis melanotus (Shaw). 

 Shaw, Zoology, 1802, 3, p. 534. Boulenger, Cat. snakes Brit, mus., 1894, 2, p. 134. 



This mainland species has been recorded from Grenada by Garman (Proc. 

 Amer. philos. soc, 1887, 24, p. 282). 



Allen did not obtain a single specimen, and it has probably gone the way of 

 most of the ground-inhabiting ophidians of the island. 



Boulenger includes within this species specimens from Colombia, Venezuela, 

 Trinidad, and Tobago. 



Urotheca dumerilii Bibron. 



Bibron, Sagra's Hist. Cuba. Rept., 1843, p. 218, pi. 24. Boulenger, Cat. snakes Brit, mus., 1894, 2, 

 p. 181. 



This snake is of peculiar interest if it is really the only Antillean species 

 existing on the Central American mainland. Neither Gundlach, Charles 

 Wright, nor any recent collector has succeeded in finding this species upon 

 Cuba. As with so many of the Cuban species sent to Paris by Sagra, it may 

 really be confined to the Central American mainland. The only specimen of 

 the species in this Museum was one sent by A. Aug. Dumeril from the Paris 

 museum. It was said to be a "type" in the loose sense in which the word was 

 then employed and may really represent one of the original series which probably 

 did not come from Cuba.
