580 MESSRS. O. THOMAS AND H, SCHWANN ON [May 29, 



Size considerably larger than in Gape specimens of G. tigrina, 

 tail longer than head and body. Fur of medium length, stiff and 

 rather coarse, about 50 mm. long on the median crest, about 

 30 mm. on flanks. 



Ground-colour on back and flanks pale sandy, whiter than 

 cream; dorsal crest strongly marked, jet-black, extending from 

 neck to base of tail; spots tawny, becoming darker on flanks, 

 small, numerous, arranged in five or six rows. Underfur grey 

 basally, pale sandy yellow terminally. Light ground-colour hairs 

 white for theii- proximal tAvo-thirds, distal third black, occasionally 

 with a faint intermediate tawny ring. Under surface of body 

 rather lighter than cream-buff. Underfur fine, thick, grey (no, 7) 

 basally, sandy terminally. Head sandy grey lighter than bodyy 

 the long hairs with wliite tips; infraorbital spot, not defined 

 posteriorly, merging into the grey of the cheeks ; ears rounded, 

 covered with short whitish-grey hairs ; lips and interramia dark 

 brownish black ; throat and chest white with faintyellow suffusion. 

 Upper surface of forearm rather yellower than back, speckled 

 with small black spots; feet yellowish white orbuffy; under surface 

 of upper arm smoky grey suffused with creamy white, forearm 

 brownish black, sharply contrasting with it. Hind limbs below 

 the knee jet-black, with the exception of a line of the ordinary 

 ground-colour passing down the front of the limb to the ankle- 

 joint ; feet dirty white with a few black hairs interspersed. Tail 

 longer than head and body, thickly covered with long coarse hair, 

 having about ten black rings, broadest towards the tip and 

 narrowest at the base ; upper s-urface of the white rings con- 

 spicuously yellow owing to the presence of tawny hairs. 



Skull decidedly larger than in G. tigrina, more heavily built, the 

 anterior wing of the squamosal more widely curved, postorbital 

 breadth greater, bullae more noticeably constricted in the middle ; 

 third upper premolar with a very well-marked internal cusp. 



Dimensions of the type (measured in the flesh) : — 



Head and body 486 mm. ; tail 496 ; hind foot 99 ; ear 59. 



The corresponding measurements of a G. tigrina (B.M, no. 

 5,5.7,41,) from Knysna are as follows : — 



Head and body 443 ; tail 397 ; hind foot 81 ; ear 49. 



Skull — greatest length 93 mm. ; basal length 85-5 ; zygomatic 

 breadth 46-4; nasals 18-8 x 7; interorbital breadth 16; brain- 

 case breadth 31-6; palatal length 44 ; length of bullas 19-5; 

 greatest diameter of p'^ 9-1 ; outer diameter of p*' 8 ; transverse 

 diameter of m^ 7-5 ; length of p^ 6-5 ; of nij 7-2,

^ This species may be distinguished from G. tigrina by its very 

 difi'erent external proportions and by the whole of the under 

 surface of the body and fore limbs being dark brown or black in 

 tigrina ard only the forearm black in G. ludia. 



The close resemblance this species bears to G. dongolana,
