 matic breadtii 39; mastoid breadth 34*3; front of canine to

Hah. Chaco of Paraguay ; type from 30 miles N. of 

 Concepcion. 



Type. Male. B.M. no. 94. 3. 6. 1. Collected October 

 1893 by Dr. J. Bohls. Two specimens. 



In the absence of fresh specimens of C. donacophilus these 

 skins from Paraguay were provisionally referred to that 

 species. Now, however, a series of skins from Bolivia, 

 collected by Mr. Steinbach, and nearly topotypical of 

 d'Orbigny's species, prove conclusively that the present form 

 needs description. Its differential characters are given above.
