against 11 x 5 in asialica), 4th 1-5. Length of the head and body; measured 
in the flesh, 94 mm.; hind foot (s.u.) 11. The skull similar to that of asiatica 
in outline, though smaller, but with the palate not extending behind the 
hindmost molar. The upper canine and foremost premolar are in contact, 
otherwise the position of the teeth is the same as in asiatica. Dimensions of 
the skull are: greatest length 22-1 mm.; basilar length 21-2; greatest width 
17; greatest height 11-3; interorbital width, posteriorly 7, anteriorly 7*8; 
length of upper tooth row, from front of incisors to back of M 3 , 9-5 ; breadth 
of palate outside last premolar 8; length of palate to base of incisors 9; 
greatest length of mandible 14-7; length of mandibular tooth row 7-8. 
Type, adult $, with fully developed mammae, taken in the sandveld at 
Klaver, on the Olifants River, Cape Province, 22nd September, 1917. The 
mammae are as in asiatica, one pair situated midway between the fore and 
hind legs, and one pair inguinal. 
Mungos pulverulentus maritimus subsp. nov. 
Intermediate between M . pulverulentus (Wagner) and M. ruddi Thomas, 
the colouration tending to that of ruddi, but with only a slight trace of black, 
in some individuals, at the tip of the tail. The colouration varies somewhat 
in individuals, a character also noted of specimens from Knysna, but is on 
the whole of a much more tawny reddish on the back and particularly on the 
tail; the base of the hair is pale grey on the back, as compared with dark 
brown to grey brown in pulverulentus , while the tail shows very little brown 
banding, this giving way to a more uniform tawny brown ; the hands and feet 
and face are also much lighter brown. In the skull also, this subspecies appar- 
ently forms a link between the two forms so far regarded as distinct species, 
but which must now be regarded as merely subspecies. For purposes of 
comparison, a specimen taken at Lormarins, Paarl District, has been taken 
as typical, and the measurements of the series, together with those given for 
ruddi, are as follows:
