On a new Species o/*Arb()n)])IiiI;u 297 



During (he last two iiionlhs (April and Maj) the bottom- 

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

 these seem to be immature Authomedusaj and Leptomcdusai, 

 chiefly the latter. Tiie e[)yra3 of Discomedusai liavc as yet 

 appeared in surprisingly small numbers.

XXXVI IT. — Description of a new Species o/ Arborophila. 

 I3y W. R. Ogilvie Guant (Nat. Hist. Mns.). 



The Natural-History Museum has for many years possessed 

 a specimen of Arhoropliila which was supposed by Gray to 

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

 llorstield 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 Horstield's Javan type, it is at once evident 

 that the two birds represent quite distinct species ; and I 

 therefore now propose the name A. samatrana for the Suraa- 

 tran species. On looking up the literature I tind 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 different 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 : —
