58 NEW SPECIES OF AMERICAN QUADRUPEDS. 
species here described ; if so, I shall be content that 
my names shall stand as synonyms. 
1. Scalops Townsendii. Townsend’s Shrew Mole. 
Scalops canadensis, Richardson. Fauna Boreali Ameri- 
cana, p. 9. 
This species, first described by Dr. Richardson, 
was incorrectly referred to the common shrew mole 
of the United States. Its size and dentition are 
sufficient evidences of its being a new and distinct 
species ; which, on account of the number and ar- 
rangement of its teeth, will either require the cha- 
racters of the genus to be enlarged, or that it be 
placed under a new sub-genus. A specimen of this 
quadruped was kindly presented to me by Mr. 
Nuttall, who requested that, in case it should prove 
a distinct species, it might be given under the above 
name. I subsequently received from Mr. Town- 
send another specimen, a little larger in size, wdiich 
I presume to be a mere variety, although very sin- 
gularly marked.
