THE HERPETOLOGY OF HISPANIOLA 99 



type has six upper and six lower labials on the right side of the head to 

 a point beneath the center of the eye; on the left side of the head there 

 are seven upper and six lower labials. The chinshields in this speci- 

 men fail to meet behind the mental, being separated by a single 

 small scale. The postnasals are much smaller and more irregular. 

 There are about 16 ventral scales and 26 lateral and 28 dorsal granules 

 in the distance between tip of snout and center of eye. M.C.Z, 

 13847, also from Gonave Island, collected in 1919 by G. M. Allen, 

 is very pale in color and practically devoid of pattern except for a 

 faint suggestion of the wide stripe along the side of the head and 

 neck. It has six upper labials on both sides, six and five lower labials 

 on right and left respectively; the cliinshields fail to meet, being sep- 

 arated by one scale; the postnasals are small, numerous and regular 

 and there are about 13 ventral scales and 23 lateral and 26 dorsal 

 granules in the distance between tip of snout and center of eye. A 

 third paratype, M.C.Z. 13322 from Thomazeau, Haiti, collected in 

 1919 by G. M. Allen, is very similar to the type in coloration, except 

 that in this paratype the dark bands on the limbs are somewhat more 

 heavily accentuated. This individual has six upper and five lower 

 labials on both sides of the head ; the chinshields are in contact behind 

 the mental; there are but two postnasals, and these are relatively 

 large, followed by much smaller granules; there are about 13 ventral 

 scales and 24 lateral and 28 dorsal granules in the distance between 

 tip of snout and center of eye. 



"Relationships. — As I have already indicated, the new species is 

 very close to the Navassa and Great Inagua species because of their 

 similarity in the arrangement of the terminal phalanges of the digits. 

 From Aristelliger cochranae of Navassa the new species differs decidedly 

 in color pattern, in having a somewhat longer snout, and in having 

 larger granules on top of the snout and between the eyes as well as 

 on the back. From the Great Inagua form, which Noble and Klingel 

 named Aristelligella barbouri, the Haitian species differs in having 

 more lamellae under the toes, and apparently also in having a weaker 

 color pattern. 



"These three species differ from Aristelliger lav of Hispaniola, A. 

 praesignis of Jamaica and A. irregularis of Cozumel in having more of 

 the digits with 'friction pads' at their terminations."
