40 DUNN — SOME HAITIAN SNAKES rVoi^VII 



Leimadophis alleni sp. nov. 



Diagnosis. — Like Leimadophis paruifrons, but with light lateral stripe 

 on upper part of scale row five, scale row six, and lower part of scale row 

 seven. Ventrals, 158-164 (average, 161.3). Caudals, female, 130. 



Type, M. C. Z., no. 12,861, adult female, Gonaives Island, August, 1919, 

 collected by G. M. Allen. 



Description. — Scutellation like that of L. parvifrons parvifrons but 

 ventrals and caudals higher in number. Color, black. Centers of scales 

 in rows one, two and three, lighter, but successively less so in ascending 

 order. A bright yellow stripe on upper corner of scale row five, on all of 

 scale row si.\ except lower corner, and on lower edge of scale row seven. 

 Outer edge of ventrals gray, belly white, upper labials white. 



This snake, which is much more strikingly colored than the 

 form on the Haitian coast, I take pleasure in naming for Dr. 

 Allen, who collected the type and who spoke to me about this 

 color difference. Besides the shading, the stripe is in a different 

 place and the ventrals and caudals are much more in number, 

 I have seen only three specimens of this form, the type and one 

 other collected by Dr. Allen, and one in the U. S. N. M. (no. 

 10,170). On only one of these is the tail perfect. 



Leimadophis tortuganus sp. nov. 



Diagnosis. — Generally similar to L. alleni, but first two scale rows with 

 dark centers, light lateral stripe on upper half of scale row six and lower 

 half of scale row seven. Ventrals (two females), 169. Caudals (one 

 female), 133. 



Type, U. S. N. M., no. 59,440, adult female, Tortuga Island; W. L. 

 Abbott, collector. 



Description. — Bluish gray on sides and dark brown above. First two 

 scale rows with lighter edges. Lower half of scale row six, black; upper 

 half of scale row sL\ and lower half of scale row seven, light. Ends of 

 ventrals bluish gray; belly light; black spots near ends of first twenty- 

 five ventrals. Another specimen (U. S. N. M., no. 59,439) is similar. 



It is interesting that in this, as well as in the Gonaives Island 

 race, the stripe is higher up the side and there are more ventrals 

 and caudals than in the races from Haiti itself. It is of course
