No. 9.— List of Mammals collected by Dr. Edward Palmer in North- 
eastern Mexico, with Field-Notes by the Collector. By J. A. ALLEN. 
Tux 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.
