teeth than the type and agrees with it in coloration. A newly-born 

 young is in the collection also. This specimen is quite different from 

 the adults, being uniform seal-brown everywhere without any of the 

 buffy grizzle of the adult except on the forehead. The type has been 

 compared with specimens in the British Museum and with measure- 

 ments and notes made from the types of crassicauda and puisa in the 

 Berlin Museum. 



The body coloration resembles closely that of the white-tailed 

 mungoose in its grizzling and also in the buff color of the underfur.

ICTONYX CAPENSIS ALBESCENS, new subspecies 



Ibean Zorilla 



Type from the summit of Mount Lololokwi, northern Guaso Xyiro 

 district, British East Africa; adult male, Cat. No. 182724, U. S. 

 Nat. Mus. ; collected by Edmund Heller, Sept. 15, 1911. (Original 

 No. 4318.) 



Characters. — Most closely allied to Ictonyx capensis intermedia of 

 the Upper Nile in coloration but distinguishable by the more exten- 

 sive white areas of the head and body, the white face markings coales- 

 cing and forming a broad band across the face or forehead ; white of 

 back very extensive, the black areas on nape and shoulders reduced 

 to narrow lines. From shoae of the Abyssinian highlands albescens 

 may be distinguished by the absence of a black bar on the forehead 

 separating the frontal and post orbital white areas, and by the more 

 extensive white areas of the back and tail ; not distinguishable how- 

 ever in size. This race exceeds the typical race capensis somewhat 

 in size and is easily separable from it by the great reduction of the 

 black areas in its coloration. 



Measurements in the flesh. — Head and body, 340; tail, 275; hind- 

 foot, 58; ear, 2j. Skull aged, all the sutures having coalesced and 

 the sagittal and lambdoidal crests well developed; the upper molar 

 shows much wear and the canines are short and blunt. 



Measurements. — Condylo-basal length, 67 ; basal length, 62 ; great- 

 est breadth, 42 ; interorbital breadth, 18 ; post orbital constriction, 15 ; 

 mastoid breadth, 35 ; palatal length, 32.5 ; upper tooth row, 25 ; 

 length of PM 4 on outer edge, j.2. 



The type is the only specimen from Mount Lololokwi, but there are 

 three others from Nairobi which agree with it in coloration. The 

 types in the British Museum have been compared as well as the 

 extensive series of specimens in that institution with the type of 

 albescens.
