On a new S2^ecief< o/Avborophila. 297 



During the last two months (April and May) the bottom- 

 net has yielded a large number of minute forms. Most of 

 these seem to be Immature Anthomedusai and Leptomedusse, 

 chiefly the latter. The epyrae of DiscomedusEe have as yet 

 appeared In surprisingly small numbers.

XXXVIII. — -Description of a new Species o/Arborophlla. 

 By W. 11. Ogilvie Gra-NT (Nat. Hist. Mus.). 



The Natural-History Museum has for many years possessed 

 a specimen of Arborophila which was supposed by Gray to 

 belong to the species A. orientalis (personata) described by 

 Horsfield from a single adult specimen obtained by him In 

 the province of Blambangan, East Java. The former bird, 

 however, which formed part of the Zoological Society's collec- 

 tion. Is marked "Sumatra," and was, in all probability, one of 

 those collected by Raffles In that Island. On comparing this 

 specimen with Horsfield's Javan type, it Is at once evident 

 that the two birds represent quite distinct species ; and I 

 therefore now propose the na;ne A. sumatrnna for the Suma- 

 tran species. On looking up the literature I find that 

 Nicholson (' Ibis,' 1883, p. 256) makes the following 

 remarks : — " The specimens sent by Mr. Forbes [from 

 Sumatra] differ considerably from the type of Arborophila 

 personata In the British Museum, being much more of a bluish 

 ash-colour on the fore neck and breast, while the back is 

 much more closely barred with black, and the flanks are much 

 more broadly and distinctly barred with black and white. 

 The diflerent plumages of this species have not been 

 thoroughly worked out ; but the Sumatran bird may ulti- 

 mately prove to be distinct." The synonymy should stand as 

 follows : —

Resembles A. orientalis, but differs In having the lores pale 

 brownish ; no white superciliary stripe ; the top of the head 

 golden brown tipped with dark brown ; the back and upper
