U. S. P. R. R. EXP. AND SURVEYS ZOOLOGY GENERAL REPORT. 



cies was written before the animal was skinned ; that it was overstuffed in the preparation, and 

 that in this state the figure was made, as well as the comparison with S. cooperi. 



St. Hilaire speaks of the ears as small and concealed by the fur, and Bachman calls them 

 large ; but these terms are purely relative, and although the ears are really larger than usual 

 in most American shrews, yet they are greatly surpassed by many European ones. The figure, 

 in fact, exhibits the eais distinctly; as much so as is required when the fur is in its natural 

 position and not pushed forward, as in Baohman's figure. 



List of specimens. 



SECTION B, WITH FOUR UPPER PREMOLARS, TEETH 30. 



Similar to section A in ears and tail ; feet small and weak ; dental formula, \ -j- ^| + ^ 30. 

 No diastema between the lateral upper tooth and first molar ; upper anterior incisor bidentate ; 

 lower anterior incisor extending back nearly to the posterior end of the second lateral tooth. 



SOREX HOYI, Baird. 



Sp. CH. Very small and slender. Ears prominent, but not quite as long as the adjacent ur, which measures scarcely one 

 and a half lines. Feet very small; the posterior, five-eighths the length of the skull. Tail about as long as the body, exclusive 

 of the head. Only four lateral upper teeth ; all the teeth large and dark colored. Anterior upper incisor with very prominent 

 serrated lobe on the inner face, in contact with its opposite. 



Color above, olive chestnut brown, with a little hoarmess ; beneath, dull rusty white. Tail bicolor. Length, about 1 \ 

 inch. Tail, 1 ' . 



Description of a specimen in alcohol, 1088. In general form this shrew is very slender ; the 

 snout attenuated, but rather broad above. The muffle is rather broad, naked, and bilobed ; it 

 projects far beyond the lower lip. The eye is small, but distinctly visible, about midway 

 between the occiput and the muzzle ; considerably nearer the anterior base of the external ear 

 than to the tip of the nose. The ear is large ; the antitragus and helix valvular, and margined 

 with hairs ; the concha rather short, hairy on the margin and edge, and directed backwards. 

 The tail is as long as the body, exclusive of the head ; it is rather thick, slightly contracted 

 at the base, tapering gently from the middle to a rather blunt tip, and with very few and 

 short hairs ; in fact, the terminal portion is quite naked. 



The feet are very small, the hinder ones disproportionately so ; the heel is hairy, except 

 along the middle line; the rest of the soles is naked, with six large tubercles among the smaller 

 ones ; those on opposite edges of the metatarsus are opposite each other. 



The colors are the same as those of the dry skin. 



Description of a dried skin, 632. General form that of S. cooperi. Muzzle perhaps less 

 elongated. Fur short, scarcely one and a half lines long. Ears of moderate size, though not 

 quite as long as the adjacent fur. The feet are small, though rather broad ; the former con 

 tained not quite one and two-third times in the latter, which is about: five-eighths as long as the
