340 BULLETIN UNITED STATES GEOLOGICAL SURVEY. [Vol. T. 



says "aus Centralamerica." Cordero's introductory remarks seein to 

 imply that his specimens were obtained in the vicinity of Jalapa. It is 

 not mentioned by Tomes as included in the collection of mammals made 

 by Mr. Salvm at Dueuas, Guatemala,* nor by Dr. von Frantzius in his 

 list of the mammals of Costa Eica.t Consequently the only information 

 I can give is limited to the material I have had opportunity of examining. 

 The localities reprsented are Jalapa, Mirador, and Tehuantepec, Mexico, 

 and La Palma, Costa Eica. As Cordero refers to his having examined 

 eight or ten specimens, it is doubtless not uncommon about Jalapa, and 

 probably ranges throughout Southern Mexico, Guatemala, and Costa 

 Eica. To what extent the habitats of the two species of Bassaris over- 

 lap still remains to be determined. The above-mentioned Orizaba speci- 

 men of B. astuta shows that the two species occur together in the State 

 of Yera Cruz, and B. astuta may be inferred to be the prevailing form 

 about the city of Mexico.
