Obs. This species is of a larger size than the Pteromys sagitta, from 

 which it differs in having the ears larger in proportion ; the tail 

 more bushy and of an uniform bright rust colour beneath ; the mar- 

 gin of the flank skin is of a reddish yellow colour, as are also the sides 

 of the face below the eye. On the upper parts of the body the fur 

 is of a deep bro-\vn, each hair being grey at the base ; the inter- 

 spersed longer hairs, which are abundant, are of a bright brown or 

 reddish-yellow colour at the apex. The general tint produced by 

 this mixture is rufous brown. On the under parts of the body the 

 hairs are of a yellow or yellowish white colour, and not grey at the 

 base. 



The specimen from which the above description is taken was pre- 

 sented to the Zoological Society by the Earl of Derby, and is either 

 from Java or Sumatra. I have taken the liberty of naming it after 

 the author of the " Zoological Researches in Java," &c. 



Mr. Gould exhibited from his Australian collection of Birds two 

 species of the genus Platycercvs, which he considered new : for one 

 of these he proposed the specific name of hcematonotus, from the red 

 spot upon its rump ; and for the other, which he had very recently 

 received, and which he remarked was one of the most beautiful spe- 

 cies of the genus hitherto discovered, that of h(Bmatog aster.

Obs. This species imites Platycercus to Nanodes, and is in fact so 

 directly intermediate between these genera in size and other charac- 

 ters, that it is difficult to decide to which group it should be referred ; 

 but I am induced to include it among the Platycerci.
