118 BULLETIN 17 7, UNITED STATES NATIONAL MUSEUM 



Of the five Sdnchez specimens (F.M.N.H No. 5963), three are 

 adults and two are young. All have a conspicuous, white, dark- 

 bordered patch on the posterior femur and adjoining part of body. 

 One of the young has two light, dark-bordered dorsal ocelli above the 

 base of the tail. Otherwise their coloration is spotted as in the de- 

 scribed specimen. They do not appear to be males, as there is no 

 ventral "escutcheon ' of scales. The two young measure 22 and 21 mm. 

 in head and body length, respectively; their tails are partly missing. 



The snout scales are weU keeled in one adult, less so in one and 

 not at all in the third. 



The dorsal scales are very unequal so that those in the standard 

 distance may be from 11 to 14 on the first adult listed, depending on 

 where they are counted. The second adult is more equal in scales, 

 but they seem slightly smaller, yet 12 to 14 may be counted anywhere 

 on back or side. The third adult has smaller scales and 15 may often 

 be counted. 



The 22-mm. young has 14 to 15 scales in the standard distance, 

 rather more than in the adults seemingly, while the 21-mm. young 

 has finer scales than any, with 15 to 16 in the standard distance. 



The chest scales are entirely smooth in all five specimens.
