242 On new Mammals from Northern Rhodesia. 



3 (32) ; width across outer .borders of m s -m 3 5'1 (5-5); zygomatic breadth 

 7-7 (7-9) ; interorbital breadth 3 (3) ; width of brain-case 6-6 (7'1). 



This pretty little bat is named in honour o£ Miss Wilson, 

 to whom I am indebted for much intelligent assistance. 



Zelotomys shortridgei, sp. n. 



Type. — An adult female collected at N'dola on June 30, 

 1919; original number 336. Five other specimens (<$, 47, 

 301, 392 ; ? , 48, 248) examined. 



This is a pallid species, differing widely in colour from 

 hildegardece and instans, the two species hitherto known, with 

 a skull of somewhat intermediate form. 



Size about as in the other species. Fur as long as in 

 hildegardece. General colour above near buffy brown, the 

 middle line of back not specially darkened ; flanks lighter 

 greyish or yellowish brown. Under surface dirty white, the 

 ventral hairs usually with slaty bases ; but -in one specimen 

 (248, old ? ) these hairs are white to the roots. General 

 ventral colour extending to lower cheeks and upper lip, but, 

 owing to the relatively pallid dorsal colour, these parts are 

 not so conspicuously contrasted with the vest of the face as in 

 hildegardece. Hands and feet dirty white. Tail almost naked, 

 dirty white in colour; the short stiff hairs, which form its 

 sparse clothing, pure white. Mammse 3 — 2 = 10, as in the 

 other species. 



Skull agreeing in size and general form with those of the 

 previously described species ; as in hildegardece, the greatest 

 zygomatic breadth is behind the level of w 3 , not in the centre 

 of the arches as in instans. Bullae decidedly smaller than in 

 either of the other species. Cheek-teeth and incisors as heavy 

 and robust as in instans, but upper incisors are not thrown 

 quite so much forwards. 



Collector's measurements of type (and those of § 248 in parentheses). 

 —Head and body 134 (137) inm. ; tail 96 (105) ; hind foot 22 (22) ; ear 

 16 (16). The hind-foot measurement in females uniformly 22, but in 

 the males (with head and body ranging between 120 and 127) it varies 

 between 22-5 and 24-5. 



Skull of tvpe and no. 248 (in parentheses). — Condylo-basal length 

 30-7 (326) ; condylo-incisive length 31 (327) ; dental length 17"2 (17T) ; 

 diastema 8-7 (9 2) ; cheek-teeth on crowns 5 - 6 (4 - 8, but worn to stumps) ; 

 zygomatic breadth 18 (18"2) ; interorbital breadth 4*5 (4-8) ; breadth of 

 brain-case at glenoid region 13 - 2 (13'3). 



This is a very well-marked species, which may be fittingly 

 associated with the name of its discoverer, Capt. Guy C. 

 Shortridge.
