269 
fulvous patches across the sides of the upper chest. The skull in essential 
characters does not differ from that of the typical race, but is larger. 
“ Head and body 89 mm. ; tail 32 ; ear 19.” Skull : greatest length 
27 *5 ; basilar length 21 *5 ; zygomatic width 15 -5 ; interorbital con- 
striction 3 ; molar series 3 -9 ; diastema 6 *8 ; length of palatal foramen 
5 -9 ; greatest diameter of bullae 5 T ; width of brain case 13 -2. 
The juvenile specimen is much smaller and slightly greyer ; but has 
the dark patches quite as clearly defined. The dark patches and dorsal 
stripes show up remarkably against the pale ground colour, and Mr. Fry 
is to be congratulated upon the excellent preservation of these characters 
when making up the specimens. 
I am indebted to Dr. Peringuey, Director of the South African Museum, 
for the loan of specimens for comparison. 
Epimys * rattus alexandrinus.

Specimens from the upper parts of the city of Pretoria usually have 
the under parts white, the hairs white to the base ; they usually frequent 
hedges of fruit trees, such as quinces and figs, but often find their way into 
the houses. On the other hand, the majority of specimens from the busier 
parts of the city, which are trapped in storehouses and large buildings 
where they seem to have taken up a permanent abode, have the under 
parts only a little paler than the upper. This seems to coincide with 
De Winton’s observations in regard to E. r. tectorum and E. r. alexandrinus 
in Egypt, except that our specimens are of about the same size in both 
forms. Specimens from the busier parts of the city are also frequently 
entirely blackish, and it is to be noted that variations between the light and 
dark coloured forms are rare.

although some of them are very old.
