nearly equally bifid, hinder ones rapidly decreasing in size : two cen- 

 tral lower elongate, above shai-p-edged, and toothed ; grinders |, 

 moderate. 



Like Crossopus, but the tail and feet not ciliated, and the noSe 

 more produced. 



* Tail moderate. Upper cutting teeth rather large, grinders mo- 

 derate.

This is probably the genus Sorex as restricted by Wagler, to 

 which he refers Sorex pygmams, Pallas, and three of his species, S. 

 rhinolophus, S. concinnus and ^S". megalodon, which are probably 

 only varieties of vulgaris : here also perhaps should be added S. con- 

 strictus, Geoffrey, which agrees with them in the ears being hid, and 

 in the face being lengthened. See Ann. Mus. xvii. t. 3. and 4.; see 

 also S. longirostris, S. Cooperi, S. Richardsonii, Bachman. 

 *** Tail short ; fore feet strong. Blarina.

To this section probably should be referred Sorex brevicaudatus 

 and S. parvus, Say, S. Dekayi, S. personatus, Geoffroy, ^S*. Caroli- 

 nensis, and S. cinereus, Bachman. 



2. Myosorex, Gray. Head elongate, ears hid under the soft 

 fur ; tail elongate, slender, covered with short, rigid, close-pressed 

 hairs, when old quadrangular ; feet and toes not ciliated : teeth white ; 

 cutting teeth f , two upper central unequally bifid, the second lateral 

 moderate, the third very small, rudimentary, the fourth small but 

 larger than the third. Front lower cutting teeth elongate, with an 

 entire sharp upper edge ; second and third lateral teeth small, simple, 

 crowded on the base of the front ones.

Like Sorex pilorides in appearance, but at once known by the 

 shape of the tail and lower cutting teeth. Teeth shining white. 



3. Sorex. Head elongate ; ears exposed ; fur soft, perpendi- 

 cular : tail elongate, tapering, with whorled scales, covered with
