The head of Scalops Breweri is narrower and more elongated than that 
of Sc. Aquations. The cerebral portion of the skull is less voluminous, the 
inter-orbital portion is narrower, each of the intermaxillary bones in Sc. 
Aquaticus throws out a process, which projects upwards and forms the 
upper boundary of the nasal cavity, and very slightly separated by the 
nasal bones, whilst in Sc. Breweri these processes are shorter and scarcely 
project upwards above the plane of the nasal bone. Thus when we view 
the snout of Sc. Aquaticus, laterally, it is distinctly recurved at the tip, 
whereas in Sc. Breweri the upper surface is almost plain. But the most 
striking difference between these skulls is exhibited in the dentition, inas- 
much as, in our present species, there are altogether forty-four teeth, in 
Sc. Aquaticus there are but thirty-six. Thus in the number of teeth Sc. 
Breweri resembles Sc. Townsendi. 
The body of Brewer’s Shrew Mole is perhaps a little larger than that of 
Sc. Aquaticus. Its snout is less flattened and narrower ; its nostrils, instead 
of being inserted in a kind of boutir, as in the European Talpa, and the 
swine, or on the upper surface of the muzzle, as in the common shrew 
mole, are placed on each side, near the extremities of the nose. This 
species is pentadactylous, like all the rest of the genus, claws longer, thin- 
ner and sharper than the common shrew mole. Palm much narrower Its 
most striking peculiarity, however, is its tail, which, instead of being round
