Typhlops platycephalus Dumeril et Bibron. 

 Dumeril et Bibron, Erpet. gen., 1844, 6, p. 293. 



A species sent from Martinique by Plee to the Paris museum. It is con- 

 fined to the island, and is very rare in collections; of its abundance on the island 

 nothing is known. 



Typhlops dominicana Stejneger. 

 Stejneger, Rept. U. S. nat. mus. for 1902, 1904, p. 687. 



Stejneger has shown that Boulenger's description (Cat. snakes Brit, mus., 

 1893, 1, p. 30) of T. platycephalus Dumeril & Bibron, based on specimens from 

 Dominica, differs in important characters from the original description based on 

 specimens from Martinique. He then proposes for the species apparently con- 

 fined to Dominica, of which in 1893 there were four specimens in the British 

 museum, the name Typhlops dominicana. 



Leptotyphlops albifrons (Wagler). 



Wagler, Spix's Serp. Braz., 1824, p. 68, pi. 25, fig. 3. Boulenger, Cat. snakes Brit, mus., 1893, 1, 

 p. 63. 



This very widely distributed species, besides being recorded as distributed 



on the Tropical American mainland, has been recorded in the Antilles from 



Watlings Island, Grenada, and Antigua. It doubtless ranges widely through 



the Lesser Antillean chain. Recently Mr. Nelson has brought back a series of 



eight specimens from Swan Islands. He reports it common there and found in 



the leaf mould of the forest, it is often seen in broad day light crawling about in 



paths and clearings. 



Leptotyphlops bilineata (Schlegel). 



Schlegel, Abbild. Amphib., 1844, p. 36, pi. 32, fig. 5-6. Boulenger, Cat. snakes Brit. mus. ,1893, 1, 

 p. 70. 



Recorded originally by Dumeril and Bibron (Erpet. gen., 1844, 6, pp. 331) 

 from Martinique and Guadeloupe. There was also a specimen from Barbados 

 in the British museum. The snake is apparently rare, and is seldom found by 

 collectors. 



Epicrates subflavus Stejneger. 



Stejneger, Proc. TJ. S. nat. mus., 1901, 23, p. 469^70. 



The Jamaican yellow boa was only separated in 1901, after very many 

 years of confusion with the Porto Rican species, E. inornatus. It has been al- 

 most exterminated by the ravages of the mongoose (Herpestes birmanicus
