SYLVISOREX GEMMEUS, new species 



Long-tailed Forest Shrew 



Type from Rhino Camp, Lado Enclave, Egyptian Sudan ; adult 

 male ; number 164644, U. S. Nat. Mus. ; collected by J. Alden Lor- 

 ing, January 14, 1910; original number, 8730. 



Characters. — Tail very long — much longer than head and body; 

 lower parts of body pearl gray. 



Coloration. — Color of upper parts, including limbs, seal brown, 

 lower sides becoming slaty, the color encroaching much posteriorly 

 on the gray of the lower parts, where only the median line of belly 

 is light. Chin, throat, chest, and median line of belly pearly gray. 

 Tail seal brown above, basal one-half lighter below. Under fur 

 everywhere plumbeous. 



Body rather thinly haired. Ears, limbs, and tail clothed with 

 minute hairs, the latter without any longer hairs near its base, as in 

 Crocidiira. Length of hair on rump, 7 mm. Tail long and cylin- 

 drical, tapering very gradually. 



Measurements. — Head and body, 69 mm.; tail, y2; hind foot, 15. 

 Skull: condylo-incisive length, 18; breadth of brain-case, 8; length 

 of upper tooth-row, 7.5 ; condylo-incisive length of mandible, 10.5. 



The skull is the same general size as that of mimdus, but differs 

 in its greater length and narrowness, and is also somewhat flatter. 

 The upper unicuspids show the same relative sizes. 



There is one other specimen in the collection from Rhino Camp 

 beside the type.
