30. Spermophilus annulatus Aud. & Back. In addition 

 to the single specimen recorded in my former paper (this Bulletin, 

 II, p. 172), Dr. Buller has sent eight others, two males and six 

 females, and three additional skulls, collected at the Hacienda 

 Nogueras, Colima, Nov. 13-15, 1889. 



Dr. Buller adds to his former notes as follows : " Local name, 

 Tesmo. Said not to occur above Ranch 'El Trapiche,' on road 

 between Colima and Tonila. Below Colima ranges to the base 

 of coast range, to where sand commences. Lives in holes in 

 sides of dykes. Also in stone walls and walls of barns, in the 

 vicinity of habitations. Food, maize, and seeds of Pasta Christi." 



The extremes of the series vary somewhat in depth of color, 

 the light tipping of the hairs of the dorsal surface varying from 

 buff to yellowish rufous, with corresponding differences in the 

 intensity of color of the sides of the neck, limbs, and ventral 

 surface.
