No. 9. — List of Mammals collected hj Dr. Edward Palmer in North- 

 eastern Mexico, with Field-Notes hy the Collector. By J. A. Allen. 



The region traversed by Dr. Palmer includes the eastern portion of 

 the State of Coahuila, the southern parts of Nuevo Leon and Tamaulipas, 

 and a large part of the State of San Luis Potosi. The specimens were 

 collected chiefly in the vicinity of the city of San Luis Potosi, but in- 

 clude a number from Monclova, Parras, Saltillo, Rio Verde, and the neigh- 

 borhood of Tampico. The remarks respecting the distribution and 

 abundance of the species, when of a general character, may be taken as 

 relating to the general region traversed. The collection throws much 

 light on the range of Mexican mammals, and in a few cases extends their 

 range much beyond their previously known limits. The detection of a 

 species of Heteromys so far northward is perhaps the most important 

 single fact of the list. The notes on the relative abundance and dis- 

 tribution of the species, written from Dr. Palmer's dictation, are dis- 

 tinguished by being enclosed in marks of quotation. 



1. Canis latrans, Say. Prairie Wolf ; Coyote. 



" Generally dispersed but not common, having been to a large extent de- 

 stroyed by poisoning and shooting." Dr. Palmer reports their occurrence in 

 small numbers in all the parts of Eastern Mexico visited by him. One speci- 

 men was sent from San Luis Potosi.
