This Tamiops is more or less intermediate between T. ro- 

 dolphei of Cochin China and Annani and T. barbel 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 out.'r and inner pale dorsal 

 lines. 



XLIII. — The Subspecies </ Paraxerus flavivittis, Peters.

(Published by permission of the Trustees of the British Museum.) 



When describing his Paraxerus flavivittis mossambkus last 

 July * Mr. Thomas was not aware of the fact that Mr. Love- 

 ridge had collected ten other exam])le3 besides the type at 

 Lumbo, Portuguese East Africa. This additional material, 

 which we owe to the generosity of Lord Sway tilling, has 

 now arrived in the British Museum. It was all collected 

 on a single day nearly two months earlier than the date on 

 which the type-specimen was cai)tured, and it forms a very 

 Itcautiful and instructive series, well worthy of somewhat 

 detailed notice. 



The new specimens show most clearly that, as in many 

 other Scinridrv, tiie coloration in P. jluvivittis is subject in 

 each individual to periodical changes of a complex character. 

 At one stage these squirrels have dark grey backs associated
