This Zamiops is more or less intermediate between T’. r0- 
dolphet of Cochin China and Annam and T. barbei of Tenas- 
serim. From the former it differs by its external light line 
being continuous with the subocular line, by the dorsal 
lineation running further forward, and by its less warm 
ground-colour. From the latter by the central division of ~ 
the ‘‘ median ” dark line, by the more buffy fore-back, by the 
much paler grey of the flanks, hips, and legs, and by the 
more equal prominence of the outer and inner pale dorsal 
lines.

XLITL.—The Subspecies of Paraxerus flavivittis, Peters. 
By Martin A. C. Hinton. 
(Published by permission of the Trustees of the British Museum.) 
WHEN describing his Paraxerus flavivittis mossambicus last 
July * Mr. Thomas was not aware of the fact that Mr. Love- 
ridge had collected ten other examples besides the type at 
Lumbo, Portuguese East Africa. ‘This additional material, 
which we owe to the generosity of Lord Swaythling, has 
now arrived in the British Museum. It was all collected 
on asingle day nearly two months earlier than the date on 
which the type-specimen was captured, and it forms a very 
beautiful and instructive series, well worthy of somewhat 
detailed notice. 
The new specimens show most clearly that, as in many 
other Sciuride, the coloration in P. flavivittis is subject in 
each individual to periodical changes of a complex character. 
At one stage these squirrels have dark grey backs associated
