8r. CH. Ears rather small, distinctly visible in the scanty fur. Longest hairs measuring about 0. 15 of an inch. Tall 

 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 1 } . Hind foot, 0. 5 of an inch. 



A single skin of what I believe to correspond to the Sorex riehardsonii of Bachman, has a con 

 siderable resemblance to S. forsteri^ as described above, but is larger, and the tail shorter in pro 

 portion. Like it 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 is a 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. forsteri. 

 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. 

 riehardsonii of Bachman, I have little doubt, from the description and locality.
