Sorer siickltyi, Baird: Suckley's 

 Shrew, W'ashinfjton to Monterej', Cal. 



Sp. Ch. Ears quite large about as 

 long as the adjacent fur. Longest 

 hairs measure nearly two lines. Feet 

 rather small, the anterior contained 

 nearly twice in the posterior, wlilch 

 barely extend two-thirds of the skull. 

 Tail considerably longer than the body 

 without the head; well coated with 

 hair; caudal vertebrate i6. Third lat- 

 eral tooth above smaller than the 

 fourth; width of skull rather more than 

 half its length. Palate | this length. 

 Color above, light chestnut brown; be- 

 neath, grayish white. Length 2] 

 inches, tail \\, hind foot .46 inch. 



This species is very closely related 

 to S. Cooperi, its distinctive characters 

 being only evident after careful e.xam- 

 ination of teeth and skull as well as of 

 e.xternal characters. The snout is 

 elongated, the ears are conspicuous and 

 are well coated with fur on the sides 

 and edges, except around and in front 

 of the moetus. 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 penul- 

 timate articulations of the adjacent 

 second and fourth. The tail is longer 

 than the body exclusive of the head. 

 The skull is short and thick for this 

 species of the group, considerably ex- 

 ceeding in this respect S. platyehincus. 

 The breadth is more than half the 

 length instead of being less. The 

 third upper lateral tooth is decidedly 

 less than the fourth. 



Sorix f^iu/iyurus, Baird: Thick- 

 tailed Shrew; habitat, Pembina, Minn., 

 to Fort Ripley. 



Sp. Ch. Ears moderate, though 

 distinct; not half as long as the adjac- 

 ent hairs. Fur very full, the longest 

 hairs measuring over 5 lines. Feet 

 and hands very stout and broad ;the lat- 

 ter contained about one and a half times 

 in the former, which are about two- 

 thirds the length of the skull. Tail 

 very thick throughout its whole length. 



with a decided pencil at the tip, about 

 seven-ninths the length of the head 

 and body alone. Third lateral tooth 

 above larger than the fourth. No in- 

 ternal lobe to the anterior upper incis- 

 ors, but these are somewhat widened 

 and in contact near the rounded point. 

 Premolars are not imbricated. Color 

 above, light olive brown becoming 

 much darker on the rump; beneath, 

 ashy white with a tinge of brownish; 

 sides of a tint of brown paler than 

 that on the top of the head. Head 

 and body 2J inches, tail to the end of 

 hairs \'\ inches. 



The body of this species appears 

 unusually stout and full owing to the 

 length of the fur which exceeds that ot 

 any American species, measuring on 

 the back as above indicated 5 lines. 

 Its large feet and claws and very thick 

 tail are also highly characteristic. The 

 ears are of moderate size, the concha 

 short, scarcely more than a line high, 

 not coming far around the moetus, and 

 much shorter than the fur. It is 

 scantily covered with hair on the mar- 

 gin of the internal face and with larger 

 ones on the edges of the supplement- 

 ary lobes. 



The skull is slender anteriorly, 

 though the muzzle is shorter than inS. 

 na\igator. The anterior upper incisor 

 is bidentate, the posterior lobe or hook 

 nearly as large as the anterior, and 

 coming down nearly to the line with 

 it and the next teeth; it is about the 

 size of the third lateral tooth. The 

 five lateral teeth overlap each other, 

 diminish gradually and regularly from 

 the first to the fifth, which is rather 

 larger than usual and visible from the 

 side. There are three very decided 

 lobed serrations on the lower anterior 

 incisor. All the teeth are chestnut at 

 the tips. 



[These descriptions of North Ameri- 

 can Mammals will continue through a 

 number of succeeding numbers, pos- 

 sibly all the year. We would be very 

 thankful to collectors for notes regard- 

 ing any of them, of their own observa- 

 tions. Ed.]
