The single specimen was found tightly coiled up under a flat rock. Nothing 

 notable is known of its habits. 



In this genus material is insufficient to define the range of this form.

The Jamaica boa is so nearly extinct that it is now rarely captured. It still 

 exists, I am told, on Goat Island off the southern coast of Jamaica in considerable 

 abundance. There are no specimens in the collection here, though the United 

 States National Museum in Washington possesses several examples. 



The species, recently separated from E. inornatus Reinhardt, has been fully 

 discussed in connection with the original description. 



Leimadophis ater (Gosse). 



Natrix atra Gosse, Nat. Sojourn in Jamaica, 1851, p. 228. 

 Dromicus ater Boulenger, Cat. Snakes Brit. Mus., 1894, 2, p. 121. 



The name Leimadophis (Fitzinger, 1843) is used for this and the following Ja- 

 maican snake, according to the distinction which Stejneger (Herpt. of Porto Rico, 

 1904, p. 694-695) has drawn between the two genera of coronelline snakes occur- 

 ring in Porto Rico. The other genus, Alsophis (Fitzinger, 1843), is not found 

 in Jamaica. 



The absence of distinct pairs of pores near the apices of the dorsal scales fixes 

 these two forms in this genus. This species may be easily distinguished by the 

 absence of loreal shield and the following scale count : scales in 17 rows ; ventrals 

 170-185; subcaudals 144-162. Compare these counts with those given for 

 Z. callilaemus (Gosse). 



It is uow extremely rare, and not a single example was taken. In the collection 

 there are three (Mus. Comp. Zool., Nos. 6007, 1 ex. ; 6005, 2 ex.), all from near 

 Kingston. James Gall collector. The National Museum in Washington has 

 four, Nos. 7375, 7332, 12364, labeled Jamaica ; No. 5093 is marked " Cuba," 

 but was taken by Mr. C. Wright, who collected in Jamaica. It is typical of this 

 species, and' without doubt the label is wrongly marked. 



Confined to the island. 



Leimadophis callilaemus (Gosse). 



Natrix callilaema Gosse, Nat. Sojourn in Jamaica, 1851, p. 384-385. 

 Liophis callilaemus Boulenger, Cat, Snakes Brit. Mus., 1894, 2, p. 142-143. 



This species may be distinguished from the one previously mentioned by the 

 following characters. A smaller adult size, the presence of a small square loreal 

 shield, and the following scale formula: scale rows 17 or 19 (regularly the 

 latter) ; ventrals 130-151, subcaudals 170-110. This form, which previously has 

 seemed far rarer in collections than L. ater, is now not uncommon in some 

 localities. The writer took fourteen near Kingston, and Mr. Wight has collected
