There is no real cusp on the inner side of p^ The transversal diameter of lUi 

 is about 2,8 mm. its length is about 4 mm. The shape of the skull is shown on 

 PL II figs 4 and 5. 



In the year 1902 Oldfield Thomas^ reviewed the then known species of ^efo- 

 gale. According to this review and later on printed descriptions the hitherto known 

 races differ from the one described above in the following points. 



Helogale undulata Peters is a much more rufous animal especially with rufous 

 face, and jsubtus undique rufus» as Peters says.^ The feet are also rufous. A 

 pointed interior cusp to p^ is present. Helogale atkinsoni Thomas has »face, crown 

 and back uniformly grizzled grey. (» Finely ticked*.) Under surface dull greyish 

 brown. Feet grizzled greyish proximally, fulvous on digits*. It appears to be smal- 

 ler than the present species the basal length of the skull being 41,7 mm. greatest diame- 

 ter of p.* 5,1 mm.; breadth between outer corners of p* 16 mm.^ Length of hind foot 

 41 mm. Helogale victorina Thomas is »pale grizzled grey suffused with ochraceous 

 yellow. Muzzle fulvous. Crown like back. Under surface from chin to anus dull 

 buffy yellow, hands and feet also buffy yellow.* Tail buffy below. Greatest diameter 

 of p* 5,5 mm.* Helogale varia Thomas » General colour above finely speckled yellowish 

 or buffy grey passing gradually below into deep buffy without speckling. * » A small 

 patch on each side of muzzle running back to surround the eye brown or brownish 

 rufous. » » Greatest diameter of p.* 5,2 mm.® Helogale hirtula Thomas. Hairs on the 

 back 18 — 20 mm. General colour as in H. atkinsoni but more coarsely grizzled. 

 Head and back appear, however, to be of the same colour to judge from the de- 

 scription. The rings of the hair said to be » white*. » Under surface as in H. atkin- 

 soni except that the belly has a more strongly marked tendency to rufous.*' Dia- 

 meter of p* 5,9 mm. 



Helogale macmillani Thomas * General colour abowe between broccoli brown 



and Mars brown* — » finely ticked with minute buffy specks* — »less 



than 1 mm. in length*. »Under surface near Prout's brown with scarcely any speckling.* 

 — j> Upper surface of hands russet.* *Front of canine to back of m^ 15,6 mm.'' 



Helogale parvula (Sundevall). The small South African species is so much 

 smaller and darker and geographically so distant from the present species that no 

 nearer comparison between them is needed, neither with the allied H. brunnula Tho- 

 mas & ScHV^^ANN from Transvaal which latter is uniform brown finely ticked with 

 buffy whitish. 



It may be quite clear from this review that the Helogale described above dif- 

 fers from all other species of this genus hitherto described. In spite, however, of 

 the differences such as the general colour, the great length of the fur, the rufous-
