While engaged in a monographic revision of North American 
Talpida3, based mainly upon the Biological Survey Collection, 
the writer has found several undescrihed species and subspecies 
of Sralopus. Since the final paper on the group will not be 
pulilished for some time, the following diagnoses are issued now :

General characters. —Intermediate in size between Scalopus a. aquaticus 
and S. a. australis, usually paler than either; skull flat, less angular than 
that of acjuaticus; rostrum long and narrow.
