38 DUNN — SOME HAITIAN SNAKES [^V^i^VlP 



from the two small islands arc characterized by increased ven- 

 tral and caudal count, as well as by the different positions of the 

 lateral stripe. The peninsula race is marked by a very low- 

 ventral count, and the interior race by its melanism. All these 

 snakes have dorsal scales, 19-17; oculars, 1-2; temporals, 1-2; 

 and labials, 8-10. 



Leimadophis parvifrons parvifrons (Cope) 



Diagnosis. — Ventrals, females, 142-143 (average, 142.4); caudals, in 

 females, 110-118 (average, 113.4). Light lateral stripe on upper half of 

 scale row five and on all of scale row six. 



Description. — Five females of this form have been examined. They are 

 the types of Dromicus 'parvifrons Cope, and were collected by Weinland. 

 The specimens came from Jeremie. Their color is as follows: Olive, first 

 three scale rows lighter; upper half or all of scale row four, and lower half 

 of scale row five, black, forming a dark stripe which passes through eye to 

 nostril. Upper half of scale row five, and scale row six, very hght, forming 

 a light stripe which starts on head. Median row (sometimes half a scale 

 on each side), black. Occasionally black dots on the end of the first few 

 ventrals. Belly hght, dotted with gray. 



Leimadophis parvifrons protenus (Jan) 



Diagnosis. — Ventrals: 150-163 (average, 157); females, 152-160 (av- 

 erage, 156); males, 150-163 (average, 159.2). Caudals: females, 110- 

 118 (average, 113.8); males, 117-128 (average, 119.3). Light lateral stripe 

 on upper half of scale row five and on all of scale row six. 



Description. — Like L. parvifrons parvifrons, but with a higher ventral 

 count. Coloration the same as L. parvifrons parvifrons.
