NEW GENUS AND SPECIES OF TPIE SORECID^i. 
compressed in front of the molariform teeth, narrowest opposite 
the third unicuspid. Unicuspicl series nearly parallel. Molariform 
series abruptly divergent. Alveolar border of maxillary deeply 
and somewhat angularly concave, the fifth unicuspid lying at the 
bottom of the concavity. Interpterygoid canal actually and rela- 
tively much broader than in either Sorex or Neosorex (in this re- 
spect resembling Crossopus), its lateral parietes nearly parallel. 
Horizontal ramus of the mandible stout and slightly convex. 
Coronoids large and high, divergent outward and inclining forward. 
Styliform angular processes much shorter than in the other genera. 
Depth of the rostrum (including closed jaw) equal to that of cere- 
bral portion of cranium. 
Hind foot more than one-fourth as long as head and body; mod- 
erately fimbriate. Tail nearly as long as head and body.

DIAGNOSIS. 
Size large ; tail nearly equal to head and body; muzzle attenu- 
ate, depressed sub-cylindrical. Unicolor : above sooty blackish- 
brown, fading imperceptibly into dark ashen-brown on throat and 
breast. Tail well haired, pencilled, absolutely unicolor. Ratio of 
hind foot to length of head and body about 26. 
First and second unicuspids subequal ; third and fourth smaller 
and subequal to each other ; fifth smallest, but nearly half as large 
as fourth, not crowded, provided with a conical, colored cusp. 
Lower incisor with two prominent denticulations ; its visible base 
extending posteriorly to a little beyond the first succeeding tooth. 
DESCRIPTION. * 
(Adult male, alcoholic.) 
External characters .- — Size large ; total length 1 50 mm. ; head 
and body 76 mm.; tail, vertebrae 68 mm., to end of hairs 74 mm.; 
manus 11 mm. 7 pes 20 mm. 
Unicolor : above sooty blackish-brown, darkest over flanks and 
hips, fading imperceptibly into dark ashen-brown on the throat and 
breast. f No trace of line of demarkation on either body or tail. 
Tail colored like back; upper and lower surfaces indistinguish- 
able. Chin soiled white. Feet same color as body. Whiskers 
* With a few exceptions the generic characters already enumerated are not here repeated, 
f Viewed in certain lights the animal has a somewhat “ peppery” appearance, which is due to 
the admixture of two kinds of hair : the longer with a nearly black awn-shapecl enlargement at the 
tip ; the shorter, a coarse fur, of uniform size throughout, and brown tipped.
