Many specimens contained fish which Dr. Chas. H. 

 Gilbert has identified with Mugil hrasiliensis. 



Natrix valida was first described by Robert Kennicott, 

 in i860, from a specimen collected in Durango, Mexico, 

 by Lieut. Couch. Professor Cope described others con- 

 temporaneously from Cape San Lucas, under the name 

 Tropidonotus tefhrofleura. Mr. Belding found the species 

 at La Paz. It appears to be the most abundant snake of 

 the country immediately surrounding San Jose del Cabo.
