18 NEW-YORK FAUNA. 



adpresscd hairs, and slightly pencilled at the tip. Teeth white at the base, pireous at the 

 tips. Dental formula : Incisors,!; cheek teeth, -j-f ^ 30. (Bachman, in his valuable mono- 

 graph cited above, attributes 18 cheek teeth to this species.) Above, the incisors are in- 

 curved, pointed, channelled behind, with a broad base dilated posteriorly, and furnished with 

 a distinct point ; the four succeeding cheek teeth on each side small, with their external points 

 most elevated ; the first of the remaining jaw teeth largest of all, with four and occasionally 

 five distinct points ; the remainder smaller, and irregularly pointed. In the lower jaw, the 

 incisors are long, not contiguous, and projecting horizontally from the jaw ; they are curved, 

 with pointed tips, and channelled within ; the external edges are sharp, with two and occa 

 sionally three distinct emarginations, the base laterally compressed. The first jaw tooth is a 

 small pointed prism, lying immediately on the base of the incisor, and directed forwards ; the 

 next is still over the root of the incisor, somewhat larger, with an oblique cutting edge ; the 

 third is five-pointed, and largest of all ; the last is somewhat larger than the second. 



Color. Uniform glossy slate, or if we take a mord definite standard, resembhng the fur of 

 the star-nose. Beneath, merely a shade lighter ; and in particular lights there is no per- 

 ceptible difference in the color, the whole appearing hoary and lustrous. Chin and nose light 

 brown. Feet flesh-colored. 



Length of head and body, . 4'8. To the end of the hairs, 0"9. 



Length of tail, 0*8. Girth, 2-7. 



I am indebted to Mr. Bell for an opportunity of examining other specimens of this Shrew, 

 from Rockland county. In one, the length of the head and body was 3'5 ; of tail, 0'7. In 

 others, the dimensions were somewhat smaller. Tlie specimens from which our description 

 is taken, were obtained from Queens county, and were described and exhibited before the 

 Lyceum of Natural History nearly fifteen years ago. I then gave it the name of concolor, 

 but the description was never published. Dr. Bachman, who examined the same specimen, 

 gave the present name, which, by the just and rigid rule of priority, must be preserved. It 

 is nearly allied to hrevicaudus, but is larger and more robust in its form. 



This Shrew is found in Albany county, and in the southern parts of the State. Its geo- 

 graphical range along the Atlantic extends from Massachusetts to Virginia.
