XXIX. — Description of a new Species of the Genus Merula 

 from the Fiji Islands. By E. L. Layard, C.M.G., H.B.M . 

 Consul for Fiji and Tonga, F.Z.S., &c. &c. 



Merula vittensis, n. sp. 



Some months since my kind friend Mr. A. Tempest, among 

 a collection of birds Jmade by him for me at Bua, on the large 

 island of Vanua Levu, gave me a specimen of a '^ Blackbird," 

 which at the time I identified, from the short description in 

 the ' Ornithologie der Viti-, Samoa- und Tonga-Inseln ' of 

 Drs. Finsch and Hartlaub, as Merula vanicoroensis. The ac- 

 quisition by myself, at Samoa, of specimens of that bird, at 

 once, however, showed me that I had committed an error ; and 

 I hasten to rectify it. 



The Fiji bird, which I propose to call Merula vitiensisj is 

 of a silky smoky brown above, not nearly so dark as vanico- 

 roensis ; below, it is grey -brown, with the same silky lustre ; 

 throat and side of neck grey ; the centre of the belly has some 

 feathers tinged with ruddy brown ; bill and legs brigiit pale 

 yellow. Length 7" 6"', wing 4" 3'", tail 3" 2'", tarse 1" 5'", 

 bilH"2". 



Mr. Tempest describes this bird as being extremely shy 

 and difficult to procure, in notes and habits resembling the 

 European bird, scratcliing on the ground under bushes. The 

 nest also is said to resemble that of A/, vulgaris.
