A species allied to G. natalensis , having the same general characters, 
but much smaller in size ; the mammae are two pairs pectoral, none 
inguinal. A specimen previously recorded from the same district as 
G. jamesoni (cf. Annals of the Transvaal Museum, Vol. Y, p. 122), belongs 
to this species. The type is an adult 9 from Arnhemburg, measuring as 
follows : — “ Head and body 125 mm. ; tail 20 ; hind foot (s.u.) 21.” 
Skull : greatest length, from the tips of the incisors to the back of the 
occipital condyles, 35 -3 ; from the tip of the exposed portion of the 
premaxilla to the condyles, 32 -3 ; and from the tip of the nasals to the 
condyles, 31 4 ; basilar length 27 *5 ; zygomatic width 23 -2 ; width of 
brain case 14-2; mastoid width 17 ; interorbital constriction 7*2 ; width 
of premaxilla at base 5; molar series 5*5; diastema 10 ‘5; length of 
bullae 9 ; nasals 12-3 X 3 4. 
Georychus rufulus spec. nov. 
The species referred to under No. 207 in my first list is apparently 
not referable to any of the southern Cape Provinces species, and therefore 
requires a name. It is characterized by having two pairs of pectoral 
mammae, a sandy-huffish coloration (nearest to “ pinkish cinnamon 5 5 
in Ridgway’s Nomenclature of Colors, 1912), and its small size ; measure- 
ments will be found in the Armais of the Transvaal Museum, Yol. IY, p. 99. 
The type is an adult 9, collected by Jameson at Tzaneen. The following 
specimens recently acquired appear to be referable to this species : — 
7 (JcJ, 1 9> Hectorspruit (Streeter).

Georychus stellatus spec. nov. 
1 A, Komatipoort (Gr. van Dam). 
This species is even more brightly coloured than G. rufulus and has 
a conspicuous white mark on the forehead. Its skull may be readily 
distinguished by the narrowness of the inter orbital constriction, a character 
which is usually very constant in all species of Georychus . It was 
unfortunately not measured properly, the length being given as 158 mm., 
probably including the tail, and the hind foot as 23 -5, which may be 
correct. The skull, which indicates that the animal was a very old one, 
measures : greatest length to tip of incisors 37 -6 ; to the tip of the exposed
