List of specimens. 



SOREX SUCKLEYI, Baird. 



SP. Cn. Ears quite largo ; about as long as the adjacent fur. Longest hairs measure barely two lines. Feet rather small ; 

 the anterior contained nearly twice in the posterior, which barely exceed two thirds of the skull. Tail considerably longer 

 than the body without the head ; well coated with hair ; caudal vertebra), 16. Third lateral tooth above smaller than the 

 fourth. Width of skull rather more than half its length ; palate, three-eighths this length. 



Color above, light chestnut brown ; beneath, grayish white. Length, 2^ inches. Tail, 1J ? Hind foot, 0. 46 of an inch. 



(Nos. 362, 1677.) This species has very close relationships to S. cooperi and platyrhinus, 

 its distinctive characters being only evident after careful comparison of teeth and skull, as well 

 as of external characters. The snout is much elongated in the prepared specimen, though 

 probably less so really than in S. platyrhinus, judging from the skull. The ears are conspicu 

 ous, though not quite as long as the fur ; they are well coated with fur on the sides and edges, 

 except around and in front of the meatus. The feet are rather small ; the anterior contained 

 nearly twice in the posterior. The palms and soles are naked, the latter with overhanging 

 hairs. The claws of the first and fifth toes reach to the penultimate articulations of the adja 

 cent second and fourth. The tail is longer than the body, exclusive of the head. The fur is 

 soft, and on the back about two lines in length or less. 



The upper parts and sides are of a rather light chestnut brown, with a slightly hoary appear 

 ance, caused by this color being still lighter penultimate to the tip of the hairs. The under 

 parts of the body and tail, with the feet, are of a brownish white or gray. 



The skull is short and thick for the species of this group, considerably exceeding, in this 

 respect, the S. platyrhinw. The breadth is more than half the length, instead of being less. 

 The dental formula is |+ g + g. The third upper lateral tooth is decidedly less than the 

 fourth, as in all the western shrews that I have examined.
