the side thus noticeably different from that of first upper 

 unicuspid. Second unicuspid, together with other mandibular 

 teeth, essentially as in S. araneus. Maxillary cheek-teeth as in 

 S. araneus, except that hypocones are less developed, that on 

 large premolar obsolete. 



Remarks. — Sorex minutus is at once distinguishable from 

 S. araneus by its smaller size and relatively longer tail, as well 

 as by the more technical characters of the skull and teeth. 

 Immature individuals of araneus might sometimes be mistaken 

 for minutus, but their larger feet will serve to indicate their 

 identity ; while if the skull and teeth can be examined, a positive 

 identification is easily obtained.
