MAMMALS-SORICINAE-SOREX F1MBRIPES.

The Rio Grande of Texas is probably the northern limit of this species, while its southern is 
yet unknown. No North American shrew has heretofore been recorded from so southern a 
locality.

The following species of North American shrews I have not yet been able to examine : 
1. SOREX PALUSTRIS. 
Sorex palustris, Rich. Zool. Jour. Ill, Jan.-Ap. 1828, 516. 
Rich. F. B. A. I. 1829, 5. 
Aud. A Bach, N. A. Quad. Ill, 1853,108, pi. cxxv. (Description and figures from Richardson’s specimen.) 
Ampliisorex palustris , Gray, Pr. Zool. Soc. Lond. V, 1837, 125. 
Crossopus palustris, Wagner, Suppl. Schreber, V, 1855, 542. 
This strongly marked species is an inhabitant of the Hudson’s Bay region, and has not yet 
been detected within the limits of the United States. It is the largest of our true shrews of the 
restricted genus Sorex , measuring 3| inches to root of tail; tail, 2-^. The back is hoary black; 
the belly ash gray. 
2. SOREX FIMBRIPES. 
Sorex Jimbripes, Bachman, J. A. N. Sc. Ph. VII, 1837, 391 ; pi. xxiv, f. 8. 
Aud. & Bach., N. A. Quad. Ill, 1854, 312. (From preceding ) 
A single specimen of this species was taken by Professor Walter R. Johnson, on Drury’s Run, 
Lycoming county, Pennsylvania, and by him presented to the Philadelphia Academy of Natural 
Sciences, where it was described by Dr. Bachman. It measured 2^ inches to the root of the tail; 
the tail, If. Above, it is of a brown color ; beneath, buff. The fur is unusually long. The 
most striking peculiarity, however, is in the very broad fore feet and the fringe of stiff hairs bor¬ 
dering them. The hands are said to resemble those of a turtle, and in truth, according to the 
description, they are broader (0.19 of an inch) than in large specimens of Blarina talpoides. In 
some respects this species would seem to approach Sorex pachyurus, described above, although 
this has by no means such extreme peculiarities of feet. 
In the long muzzle, broad fore feet, and full fur, there is an approximation to the genus 
Urotriclius, of much interest.
