Batchelder An Undescribed Shrew. 



FIG. 26. Skull of Sorex macrurus$ 



Colors (of type, noted in the flesh). 

 Upper parts between ' slate-color ' * and 

 ' blackish slate' ; 1 under parts dark ' smoke 

 gray' 2 or brownish 'mouse-gray'; 3 tail, 

 above, browner than back ; edge of lips 

 and under side of tail, brownish flesh 

 color; upper side of both hind and fore 

 feet between ' fawn-color ' * and ' ecru 

 drab.' 4 



The specimen from Mt. Marcy ($, ad. 

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

 differs in color from the type only in 

 having a slightly more plumbeous tint, a 

 difference due, apparently, merely to its 

 pelage having been exposed to several 

 Type (x 2). " 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 deeply 

 excavated posteriorly. 



Measurements (of type, 

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



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

 mm. ; height of ear, 10 mm. The Mount Marcy specimen 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. trowbridgii, 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 personality, but in this respect macrurus 

 is even more remote from such species as trowbridgii or fumeus than is 

 personatus itself.
