KEY TO LAND MAMMALS OF NORTHEASTERN NORTH AMERICA I4I 



Condylura cristata (Linnaeus) Star-nosed mole 



1758 Sorex cristatus Linnaeus, Systema naturae, ed. 10. 1:53. (Penn« 



sylvania) 

 1819 Condylura cristata Desmarest, Journal de physique. 89:230. 

 1896 Condylura cristata True, Proe. U. S. national museum. 19: 78. 



Dusky brown, paler and grayer below. Total length, 170 (6f ) ; tail verte- 

 brae, 72 (2|) ; hind foot, 27 (lA). (cristata; Lat., crested) 



The star-nosed mole inhabits wet places in the boreal and transition 

 zones of eastern North America. Its northward range is more extensive 

 than that of any other American species. 



Genus Scalops IlHger 



1811 Scalops Illiger, Prodr. syst. mamm. et avium, p. 126. Type Sorex 

 aquaticus Linnaeus. 



Teeth 36; nostrils on upper side of simple muzzle; tall short, not tUcTcened^ 

 nearlynaked. (Scalops; Gk., a mole) 



The genus Scalops is confined to eastern North America. It con- 

 tains five or six forms whose interrelationships are not fully understood. 

 Only one of these occurs within our limits. 



Scalops aquaticus (Linnaeus) Naked-tailed mole 



1758 Sorex aquaticus Linnaeus, Systema naturae, ed. 10. 1 : 53. (East- 

 ern United States) 

 1825 Scalops aquaticus F. Cuvier, Dents des mammiferes, p. 251. 

 1896 Scalops aquaticus True, Proc. U. S. national museum. 19 : 19.

 162 (6|) ; tail vertebrae, 27 (ItV) ; hind foot, 16.5 (f ). (aquaticus; from Lat., 

 aquatic) 



The naked-tailed mole inhabits dry sandy soil in the eastern United 

 States and southern Canada from the northern limits of the transition 

 zone southward. The form found within our limits is the typical sub- 

 species, S. aquaticus aquaticus. 



Genus Parascalops True 



1894 Par as cal ops True, Diagnoses of new North American mammals. 

 26 Ap. 1894. p. 2. (Reprinted: Proc. U. S. national museum. 15 Nov.

Teefh 44; nostrils on outer side of simple muzzle; lad short, thick; ihitseh/
