 skull, March 10, ls:).5. 



Skull lacks posterior portion of brainca.se; otherwise perfect. 8kin lost. 



Type not desi<:nated by number. In the original description it is said; "Col- 

 lected near Chihuahua by John Potts, eeq." Reference to Baird's Mammals of 

 North A merica, page 942, shows that no. -f/-\ is the only one to which that remark 

 applies and it is thus reganled as the tyi)e. Unfortunately it was witiiout a tail, 

 and that is undoubtedly the reason why the measurements of another specimen, 

 No. 5(55, are given in the original description.
