This pretty flying-squirrel I have named in honour of 

 Mrs. Steplienson Clarke. It is distinguished i'rom the 

 Trogopterus of Central China, T. mordaxj by its less buflfy 

 colour and its smaller^*. In the absence of the buffy colour 

 below, especially on the parachute, it is distinguishable from 

 all the members of the genus. 



In working out Mr. Forrest^s Li-kiang Trogopterus^ I have 

 re-examined the two specimens from the Upper Min River 

 referred to T. mordax in the original description of the latter, 

 and now think that they are referable to yet another highland 

 species, which may be termed
