whicli lias relatively larger scales; in the absence of a preoccipital, 

 the occipital being completely separated from the supraorbital semi- 

 circles by one row of small scales; in the somewhat shorter snout; and 

 in the larger scales of the gular fan. While some deviations wiU 

 naturally be found in a series, it is probable that the scaling of the 

 tail, the color pattern on the neck, and the larger scales on the gular 

 fan will prove to be fairly stable. 



A second specimen was secured by the Utowana Expedition when 

 it touched at Beata Island on April 11, 1934. This example is now 

 M.C.Z. No. 37520.

Diagnosis. — Obviously close to dominicensis but distinguished from 

 it by having a black shoulder patch bordered above by parallel light 

 stripes, the lower contmuing from below the ear to beyond the axilla ; 

 in having larger scales on the tail and a less-pronounced scalloping 

 of the crest; in not usually having a large preoccipital; and finally in 

 having, on the average, more scales in the median patch just anterior 

 to the juncture of the supraorbital semicircles. 



Description oj the type. — U.S.N.M. No. 76801, male from En Cafe, 

 Gonave Island, collected in March 1929 by A. J. Poole and W. M. 

 Perrygo. Head short, with two short and very weakly developed 

 frontal ridges diverging forward and becoming indistinct at a tliird 

 of the distance from the eyes to the end of the snout; forehead slightly 

 concave between these ridges; head scales smooth; rostral very low, 

 narrower than the mentals; four to six scales between the nostrils, 

 the inner two of these scales the foremost in a paired median series 

 of rather rectangular, somewhat enlarged scales, which are in contact 

 as far as the concave region in front of the eyes where the series 

 separate to enclose a patch of about eight irregular scales; three 

 scales of the supraorbital semicircles in contact behind this patch; 

 occipital a little larger than the ear opening, elliptical, shield-shaped,
