color, washed on the sides with bluish; outer ventrals, edges of the 

 lateral spots often reticulated or marked with black. 



Variatioyi: — A female (same data as above) differs from the male 

 in being more brightly colored. The dark lateral bands are almost 

 black. On the back between these two bands there is a regular longi- 

 tudinal series of two rows of dark spots. The dark bands on the 

 sides are bordered by a series of pale spots. The flanks below the 

 bands have each one or tw^o more rows of similar spots. The outer 

 ventrals are heavily marked with brown instead of black. A young 

 male (same data as above) is similar to the adult female except that 

 the region below the dark bands is considerably darker. 



Remarks: — The description was taken from an adult male that 

 measured one hundred and twenty -two millimeters from snout to vent. 



Habitat: — Apparently' confined to St. Vincent and Grenada, though 

 it is probable that it also occurs in some of the Grenadines. In spite 

 of the mongoose this species which was once almost exterminated 

 seems now to be on the increase, — a peculiar fact due probably to the 

 lizards' change of habits. Dr. Allen noticed this in Grenada and the 

 same thing has been reported in Jamaica as happening with Ameiva 

 dorsalis. 



List of specimens examined. 



x\meiva tobagana (Cope). 



Dr. Stejneger has been kind enough to supplement photographs of 

 the type of this species, with the following excellent description. 



" Rostral forming an acute angle behind; nostril between two nasals; 

 anterior pair of nasals broadly in contact behind rostral; frontonasal 

 longer than wide, in contact with nasals, loreal, and prefrontals; 

 prefrontals broadly in contact; frontal pentagonal, in contact with 

 first and second supraoculars, well separated from third; a pair of 

 frontoparietals in contact with second and third supraoculars ante- 

 riorly; five occipitals in a transverse row, much longer than wide,
