shorter, rounded tail; Orthotonus, on the contrary, has a cuneate tail, 

 whereas in this genus the tail is only graduated. The wings are a 

 little longer and less rounded than in Or t ho totnus, the fifth and sixth 

 quills being the longest, the fourth and seventh scarcely shorter, the 

 first considerably shortened, half of the fifth ; the bill is straight, at- 

 tenuated and subulate, a little more robust than in Orthotomus, as 

 are likewise the legs and feet.

Mr. Kleinschmidt discovered this remarkable little bird during an 

 expedition into the interior of Viti-Levu, but could obtain only a 

 single specimen. 



Myiolestes nigrogularis, Layard. 



Lalage! nigrogularis, Layard, P. Z. S. 1875, p. 149. 



Mr. Layard has described this interesting bird wrongly as a Lalage : 

 it is a typical Myiolestes, agreeing in its generic characters with 

 our M. heinei (H. & F., P. Z. S. 1869, p. 546) from Tongatabu. 

 Mr. Layard, strangely enough, does not mention this characteristic 

 bird in his last paper on Fijian birds (P. Z. S. 1875, p. 423). 



Mr. Kleinschmidt obtained but one specimen of this species at 

 Ovalau. 



Rhipidura albogularis, Layard {nee Less.). 



One specimen, agreeing very well with Mr. Layard's description 

 (P. Z. S. 1875, pp. 29, 434). This is a very excellent and peculiar 

 species, not to be confounded wiih any of its allies. 



Myiagra castaneiventris, Verr. 



One old male as figured (F. & b H. Orn. Centr.-Pol. t. ix. f. 2), and 

 corresponding in every respect with specimens from the Navigators' 

 Islands.

[Keceived December 9, 1875.] 

 In no work on anatomy with which I am acquainted can I find 

 any reference to the peculiarities of the caecum coli of the Capybara,
