(2) Forms allied to C. cancrivorus, in which P-_4 is rather small, averaging 100 to 125. (3) Forms allied to C. parvidens (C. vetulus of Burmeister, but not of Lund), in which P- 4 is extremely small, averaging 100 to 160. If these views are not mistaken, the species and varieties will stand thus:- I. C. cancrivorus. Brazil. Variety (a) : brasiliensis. Brazil. II. C. microtis. Brazil. III. C. azarce.
