nearly equally bifid, hinder ones rapidly decreasing in size : t\vo cen- 

 trai lower elongate, above sharp-edged, and toothed ; grinders |, 

 moderate. 



Likę 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 pygmoius, Palias, and three of his species, ^S". 

 rhinolophus, S. concinnus and S. megalodon, \vhich are probably 

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

 strictus, GeofFi'oy, \vhich agrees with tliem 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.

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

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

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

 cutting teeth |, two upper centrai unequally bifid, the second lateral

 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.
