May, 1907.] Collection of Bafrachians and Reptiles. 155 



5^oung specimens. C. espentii, according to Cope, is "confined 

 to certain islands of the eastern coast of Central America," but 

 this collection would make it appear that the species occurs 

 ■commonly on the mainland. The specimens were collected as 

 follows :

(b) Cnemidophorus deppii is represented in this collection by 

 13 specimens, 9 adults and 4 young. This species is restricted to 

 Central America, and is closely ahied to C. guttatus. In some 

 of these specimens the anal scales are not entirely continuous 

 with the abdominal scales as described by Cope, in four spec- 

 imens there are some small scales between the larger abdominals 

 and anals. Seven specimens have three pre-anal plates and six 

 specimens have only two per- anals. The length varies from 3f 

 inches to 9^ inches ; the average length of the adults is 7f inches, 

 all above that length are males.
