FEB. 1903. MEXICAN MAMMALS ELLIOT. 147 



Measurements. Total length, 185; tail vertebrae, 106; hind 

 foot, 24. The skull is badly broken and no measurements are 

 possible. 



Dr. Merriam has raised the members of this group of the 

 Heteromyidae to generic rank under the title of Liomys (1. c. ). It 

 does not appear to me that the characters he gives are sufficiently 

 distinctive and important for this, as adults of Liomys and 

 Heteromys in a number of instances cannot be distinguished 

 apart by their teeth and therefore Liomys is here employed as a 

 subgenus. I sent the specimen of H. exiguus to Dr. Merriam to 

 be compared with his large series, and he writes me that "it is 

 different from any species known to me, although it is closely 

 related to L. torridus minor. Our collection does not contain 

 anything like it."
