REPORT OF NATIONAL MUSEUM, 189S. 



iition alone would not distinguisli tlic two as species, although 

 strikingly different. The differences are, however, important. First, 

 the generic characters of two internasals, and an interoccipital plate. 

 Second, the hind limb is materially shorter, since when extended it 

 only reaches the elbow of the forelimb. Third, the third infralabial 

 is not so large, and does not reach the labial border. There are five 

 inferior labials reaching that margin instead of four. The third (last) 

 pair of preanal plates is not so disi)roportionately large. As points of 

 minor importance may be added the ])resence of two wide scales 

 between the second pair of infralabials instead of one; and the fact 

 that the dark color of the superior surfaces appears on the sides of the 

 throat and abdomen, and on the inferior side of the tail, which it does 

 not in the A', picta.

 ZABLEPSIS HEN8HAVII STEJNEQER. 



California. 



Cat. No. 20339, U.S.N. M. 



Concerning this species Mr. J. Van Benburgh remarks that at Witch 

 Creek, San Diego County, California, it lives among the numerous 

 granite bowlders, and comes out into the narrower crevices between 

 them a few minutes before dark. It is, therefore, practicable to hunt 

 for it only about fifteen or twenty minutes each day. If a bit of string 

 or a straw be introduced into the domain of one of these lizards it will 

 often be seized, the reptile apparently mistaking it for an insect.^
