77. Chilomeniscus cinctus Cope 



The only specimen of this species taken by Mr. Slevin was 

 found under a pile of debris close to a house in a street of 

 Todos Santos. The species is known to the natives, who say 

 it is rare and that they do not see many. 



80. Trimorphodon lyrophanes Cope 



One specimen of this snake was collected at San Jose del 

 Cabo. It was found in the thatched roof of a house late in the 

 afternoon as it was crawling over the rafters. The food of 

 this snake consists, at least in part, of small mammals, as this 

 specimen had in its stomach the remains of a mouse or some 

 small mammal with long hair. 



81. Crotalus lucasensis Van Denburgh 



Although supposed to be the most common rattlesnake of 

 the Cape Region, only a single specimen was collected. This 

 was found in the vicinity of Agua Caliente, just at dusk, cross- 

 ing a road. The stomach of this specimen contained the re- 

 mains of a small mammal.
