Fig 25 — SiiuH of Soiestr /Hacrui-iiS(f 

 Type (X 2). 



Colors (of type, noted in the flesh). — 

 Upper parts between ' slate-color ' ^ and 

 ' blackish slate' ; ^ under parts dark 'smoke 

 gray'^ or brownish 'mouse-gray';^ tail, 

 above, browner than back ; edge of Wps 

 and under side of tail, brownish flesh 

 color ; upper side of both hind and fore 

 feet between ' fawn-color ' * and ' ecru 

 drab."^ 



Tlie specimen from Mt. Marcy {(^, ad. 

 Aug. 1, 1896, No. 1386, coll. C. F. B.) 

 diflers in color from the type only in 

 having a slightly more plumbeous tint, a 

 diflerence due, apparently, merely to its 

 pelage having been exposed to several 

 weeks less wear. 



Cranial and dental characters. — Skull long and slender; brain-case low, 

 narrow, and little inflated ; rostrum long, narrow, and low ; palate rather 

 narrow. Posterior border 

 of infraorbital foramen ly- 

 ing over a point consider- 

 ably behind the interspace 

 between the first and sec- 

 ond molars. Unicuspidate 

 teeth slender; the first and 

 second about equal in size ; 

 the third and fourth small- 

 er, and subequal — if any- 

 thing, the third slightly 

 shorter than the fourth. 

 Molariform teeth dee])ly 

 excavated posteriorly. 



Measurements (of ty})e, 

 taken in the flesh). — Total Fig. 28.— Same tooth row, seen from below, 



length, 130 mm.; tail vertebra?, 60 mm. ; hind foot, 15 mm. ; fore foot, 8 

 mm. ; height of ear, 10 mm. The Mount ]Marcy sjiecimen measured : total 

 length, 139 mm. ; tail vertebrae, 61 mm. ; hind foot, 15 mm. ; ear, 10 mm. 

 The extreme tip of its tail appears to have been lost by some accident. 



This Shrew differs so widely from all others with which I am ac- 

 quainted that comparisons with any other species are quite unnecessary. 

 In color and size it bears a slight superficial resemblance to Sorex fumeus 

 and to S. trombridgii, but it is at once distinguishable from them by its 

 long tail, even without reference to its cranial and dental characters, in 

 which it is totally unlike these species. In the general shape of the 

 skull there is a suggestion of Sorex personutus, but in this respect macrurus 

 is even more remote from such species as trou-bridgii or fumeus than is 

 jjersonatus itself.
