131. Dendromus longicaudatus , spec. nov. 
Very similar to D. melanotis, but with a longer tail and larger skull ; 
in colour, also, rather brighter rufous in general effect. Type : Old ex 
collection H. L. Jameson, Tzaneen Estate, Transvaal, 21.7.07. “ H. and B. 
76, tail 107, hind foot 19, ear 16*5” ; skull: gr. leng. 23, bas. leng. 17, 
gr. br. 11*8, molar ser. 3*3. 
132. Dendromus mesomelas , (Brants). 
2, Knysna (?), skulls in skins. 
These'two specimens are without labels, but one at least of the skins 
is prepared like those of Rex of Knysna. 
133. Dendromus Ayresi , spec. nov. 
Rather darker coloured, as a rule, than D. mesomelas and smaller in 
size, but like that species in having a dorsal stripe in adults, and with 
claws to four toes. 
This species is represented by four fully adult and five younger 
specimens taken by II. H. Swinny, and one, like the five, taken by 
Shortridge, at Port St. Johns. The following table of measurements of 
striped and unstriped specimens will show that there is good reason for 
supposing the former to be fully adult and the latter to be younger : —

I have named this species after my old friend the well-known 
naturalist, Mr. Thomas Ayres; he remitted some specimens to Mr. Sclater, 
who referred them to D. mesomelas in his “ Fauna of South Africa.” 
134. Dendromus pumil/io, (Wagner) (?). 
At Port St. Johns another striped species is found which is coloured 
like D. mesomelas, but it is smaller even than Ayresi : and as the unstriped 
specimens are smaller than the striped and measure about the size as 
Wagner’s Mus pumilio , it is not unlikely that the species was described 
from a young individual.

An old striped $ collected by Dr. H. L. Jameson at Sweet waters in 
Natal is very slightly larger than these from Pondoland, but still not as 
large as the
