apparently be referred to G. nanus ; but in the type of tzaneenensis the 
tip of the tail is the same colour as the rest ; the end of the tail is missing 
in the cotype ; the Woodbush specimen is identical with that of the type. 
The smaller teeth distinguish this form from the typical one.

In all the old specimens of tzaneenensis the tail measures over 160, 
usually about 170 mm., whereas in equally old specimens of either sex of 
pretori* it seldom reaches 160, usually measuring 150 to 155 mm. These 
series of skins with skulls, together with those previously recorded (Ann. 
Tvl. Mus., Vol. IV, No. 2, p. 85), seem to indicate that pretori* is a distinct 
species characterized by having a shorter tail than chrysophilus. Speci- 
mens from Zoutpan and Moorddrift are brighter yellowish than the 
typical ones from the hills above Pretoria and should perhaps be referred 
to another race, especially if pretori* proves to be a distinct species. 
The number of mamin* is six, that is, one pair pectoral and two pairs 
inguinal ; but the pectoral pair does not appear ever to be fully developed 
or brought into use. 
Mus namaquensis Grahami subsp. nov. 
Mr. Hewitt, curator of the Albany Museum, has sent me three speci- 
mens of this species for identification ; they were collected by Master 
R. Graham at Godwin’s Kloof, Grahamstown, and as they are referrable to 
a remarkably long-tailed race, I am naming it after him in recognition of 
the assistance he has rendered the Albany Museurg in collecting a number 
of interesting small mammals. 
This subspecies is larger in all respects than any other form of the 
species previously described ; in fact, it approaches Mus chrysophilus in 
this respect, though it is obvious from the narrowness of the skull and 
the teeth that it is a larger race of M. namaquensis. In colour it 
resembles a specimen we have of the typical form from Klipfontein. 
The measurements of the length of head and body and tail seem to have 
been wrongly taken, the former having been taken to the base of the 
scaled portion of the tail, and the latter thence to the tip without the hair;
