THE HERPETOLOGY OF HISPANIOLA 



343 



Color (in alcoliol): Upper surface of head, body, and tail deep cobalt 

 blue; a very definite white line beginning at the snout, passing along 

 the upper labials and continuing on the body on the upper half of the 

 first and the lower half of the second scale rows ; chin and throat pak 

 turquoise blue; the remainder of the ventral surface pale drab-gray. 



Variations. — In this series it may be seen that the variation of 

 ventral plates is between 192 and 212, and caudals between 184 and 

 214. The variation of the head shields of this species is remarkably 

 small. Few specimens have any variation in the number of supra- 

 labials— U.S.N.M. Nos. 55300 and 66972 have nine upper labials on 

 both sides of the head, and No. 69198 has nine on one side only. One 

 other specimen has two anterior temporals on one side of the head. 

 Two snakes have a single postocular, and these same individuals are 

 further distinguished by lacking loreal plates; in No. 10167 there is a 

 very minute loreal on the left side only. 



The diameter of the eye in relation to the length of the snout is 

 a constant ration of 1 to 3 in all these specimens.
