Two specimens, one of each sex, in the Biological Survey collection 

 from Santo Domingo (U. S. N. M. Nos. 37644, 37646) greatly extend the 

 range of this species which has hitherto been known only from the type 

 locality, Ballenas Bay, and San Bartolome Bay (Albatross collection). 

 The occurrence of a species characteristic of the Vizcaino Desert district 

 on the Magdalena Plain adds to the evidence that the latter is faunally 

 more closely allied to the Vizcaino area than to the Cape district proper, 

 as I have elsewhere indicated.

In the male specimen from Santo Domingo the fringes of the toes 

 appear to be less strongly developed than in specimens from San Barto- 

 lome Bay, but the specimen shows signs of having been subjected to 

 friction, and the points of some of the fringe scales are broken off. There 

 are four lateroventral bands on one side, three on the other. The female 

 specimen has the fringe scales well developed.
