In spirits : 1, Knysna, and 2, Lydenburg. 
This species is the smallest of the group found in South Africa, and, 
as with the preceding, the unstriped specimens are invariably the smallest 
in the series. In colour it is like D. mesomelas , but has a broader dorsal 
stripe. 
As there is no material difference in the size between specimens from 
Tzaneen and Port St. Johns, I have included them all under one head in 
the following table : — 
Striped <J<$ (fi). Striped (2). Unstriped (1(^, 1$).

136. Dendromus Wliytei, Wr. 
1 old 5, 1 young from same nest, Boror (Kirby and Roberts). 
The young specimen has not yet cut its last back tooth, but the skull 
measures 17*5 as against 20 in the mother. From this it would seem that, 
as with the majority of insectivorous mammalia, the skull is not very 
much smaller in the very young than in the fully adult. This supports the 
supposition that the unstriped individuals from Port St. Johns are the young 
of the species next in size above them in the scale, although it still does 
not prove that a species which never assumes the dorsal stripe does not 
occur in South Africa. I may here mention that in the series of striped 
specimens of the three species found at Port St. Johns nearly every month 
of the year is represented in the dates of capture ; whereas, in the 
unstriped specimens, only the winter months are recorded. The details 
are as follows — 
D. Ayresi, one in March, one in May, and five in June. 
D. pumilio { ?), one in each month, April, June, August, and Sep- 
tember. 
D. Jcimesoni , two in June.
