collection of the Zoological Society of London, undoubtedly from America, but the particular 

 district was not known. 



The Shrew-mole has a wide geographical range, being found from Carolina to the fiftieth 

 degree of north latitude, and from the Atlantic to the shores of the Pacific. 



GENUS SOREX. Linneus. 



Cutting teeth, f ; the upper curved and notched at the base. Head elongated ; snout pro- 

 duced and moveable. Ears short, rounded, broader than long, concealed, occasionally not 

 elevated above, the skull. Feet short, with Jive nails; phalanges small, separate, with 

 feeble hooked nails. A series of glands, exhaling a strong odor, along the flanks. Cheek 

 teeth, ^„^. • 



Obs. This geniis contains some of the smallest of our quadrupeds. The English translator 

 of Cuvier's Regne Animal, asserts that no genuine Shrews are to be found, except on the 

 ancient continent ; an assertion which is contradicted by the fact that thirteen species have 

 been described in North America, and when farther investigations arc made, the number will 

 probably be much increased. It will be found that the characters of the genus will require 

 careful revision, and several small but distinct groups will be established. The habits of the 

 animals of this genus are nocturnal, and they burrow for the most part in the ground like the 

 shrew-mole. All are said to be fond of the water, swimming with great ease, and diving 

 well.
