SOREX RICHARDSONII. 
Sorex richardsonii, Bacuman, Jour. A, N Sc. Ph. VII, 1837, 383; pl. xxiv, f. 5. 
Avp. & Bacu., N. A. Quod, IIT, 1854, 334, (from Bachman.) 
Waener, Suppl. Schreb. V, 1855, 546. 
? Sorex parvus, Ricuarpson, F. B. A.I 1829, 8. 
Sp. Cu.—Ears rather small, distinctly visible in the scanty fur. Longest hairs measuring about 0.15 of aninch. Tail 
shorter than the body; scant haired. Color above, rusty iron gray ; insensibly paler beneath. Feet and under side of tail 
brownish white. Length, 2? inches. Tail, less than 14. Hind foot, 0.5 of an inch. 
A single skin of what I believe to correspond to the Sorex richardsonii of Bachman, has a con- 
siderable resemblance to S. forsteri, as described above, but is larger, and the tail shorter in pro- 
portion. Likeit the ears are small for this group, less than in the much smaller S. cooperi. The 
tail is shorter than the body, exclusive of the head ; but scantily provided with hair. The hairs of 
the back are very short, only about 0.15 of an inch. There isa distinct gland on the side, 
about one-third of an inch long, and one-twentieth wide, covered with short close silky hairs, 
indicating the position of the musk gland. The dentition appears similar to that of S. forstert. 
The color above is a rusty iron gray, the under parts a little lighter. Feet, and under surface 
of tail, light brownish yellow. ; 
I regret that the condition of the specimen does not admit of a more accurate description, nor 
do I feel at all confident that it is really distinct from S. forsteri. Of its representing the S. 
richardsonit of Bachman, I have little doubt, from the description and locality.
