The skin is well made up, probably remade, but the specimen has a worn and 

 dirty look about it. PkuU nuich broken, but now patched up, so that the 

 missing parts are the two zygomatic arclies, the last left ujiper molar, and the 

 angular, condyloid, and coronoid ])roceases oi the right half of the mandible. 



Type not designated by number, but it is mentioned as one "colletited by the 

 Boundary Connnission under ISIajor (irahain." Referring to Bainl's ]\Iammals 

 of North America, page 47(5, there are l\nuid t<> l)e three specimens collected b\ 

 that commissi(m — nos. 144, 14G, and 147. The measurements of no. 140 agree 

 very closely with the measurements given by Le Conte; no. 144 does not agree 

 with them at all, and of no. 147 no measurements are given and the specimen 

 itself can not be found. No. 14(5 is evitlently the ty])e. It was so conside?-ed 

 and marked by Coues in 1877.
