210 On new Bats from British East Africa, &c, 



the British Museum is indebted for so many interesting 

 Chiroptera and Kodentia. 



M. Hildegardem is readily distinguishable from any of its 

 allies by its striking coloration, as it is far brighter in tone 

 than either il/. Bocagei ox M. Goudoti, the species most similar 

 to it. 



JSyctinomus Ilindei, sp. n. 



A whitish-winged member of the N. pumilus group. 



Essential characters of ears, tragus, skull, &c., apparently 

 as in N. limbatus, Peters. A marked tuft of brown hairs 

 behind the joining membrane of the ears. 



Colour of upper surface chocolate-brown, finely flecked 

 with white ; tiie bases of the hairs (which attain about 

 4-4*5 mm. in length) rather lighter. Under surface brown, 

 more or less washed superficially with whitish, especially 

 along the middle line of the belly ; a creamy white line 

 edging the junction of the wings with the flanks. Ears, 

 forearms, hind limbs, and interfemoral membrane dark brown. 

 Wing-membranes near the body whitish brown, paling to 

 white on the middle part of the wing, and darkening again 

 at the tips to brown. 



Skull about as in N. Emini, though with less marked pre- 

 orbital processes. Small upper premolar outside the middle 

 line of tooth-row, less crushed than in limhatus, more so than 

 in Emini. Middle lower incisors deeply bifid. 



Dimensions of the type (measured in skin) : — 



Forearm 40 mm. 



Head and body (c.) 61 ; tail 35; thumb close to membrane 

 6; third finger, metacarpal 39, 1st phalanx 15*5; fifth 

 finger 39. 



Skull : greatest length 17"6 ; basal length 14'6 ; zygomatic 

 breadth 11'4 ; front of canine to back of m^ 6"7. 



Hab. Fort Hall, Mt. Kenya district, British East Africa. 

 Alt. 4000 feet. 



Type. Adult male. B.M. no. 3. 3. 2. 4. Original number 

 134. Collected 1st Jan., 1903, and presented by Mrs. Hinde. 

 Two specimens. 



This Nyctinomus is most closely related to N. Emini, 

 de Wint., of Usambiro, German E. Africa *, but differs by 

 its whitish wings and more closely crushed upper premolars. 



• Not Mosambiro, as accidentally printed in the original description, 

 Ann. & Mag. Nat. Hist. (7) vii. p. 41 (1901).
