The skull of A. Jierciiles Rehn has been kindly sent to mebv Mr. 

 Stone from the Phil. Acad. Collection. The differences in the size 

 of the teeth, so much larger in the two specimens of the new form, 

 the shape of the condyle, and the cranial characters mentioned, are 

 very conspicuous, and seem to mark the Guiana specimens as quite 

 distinct.
