Cooper astur poliogaster, Temm. — A very rare Brazilian 

 ^J3awk, allied to C. bicolor : cf. Ibis, 1881, p. 258. 



Cooperastur gundlachii, Lawrence : Cuba. — Differs from 

 C. cooperi in its ash-coloured breast and sides when adult, 

 and in having less white on the under surface. (Cf. ' Studies 

 of American Falconidse/ 1876.) Ibis, 1875, p. 469. 



Megatriorchis dorice, Salvadori : Eastern New Guinea. — 

 Figured in Sharpe's ' Birds of New Guinea/ i. pi. iii., where 

 it is stated to have also been obtained in Northern 

 Australia. Dr. Sharpe gives the following measurements : — 

 Length 20 inches, culmen 1-05, wing 12*8, tail 100, tarsus 

 3'1. Eyes chestnut-brown; tarsi bare. General colour 

 above glossy black in the adult, brown barred with lighter 

 brown in the young. Ibis, 1878, p. 87. 



Morphnus iteniatus, Gurney. — Apparently the only speci- 

 men known is the type obtained by the late Mr. C. Buckley 

 in Ecuador, figured in the f Ibis ' for 1879, pi. iii. 



Thalassa'etvs branicIcii,Ta.cz.: the Corea. — A young one now 

 in the Zoological Gardens seems exactly the same size and 

 bulk as a Sea-Eagle (H. obicilld) in the next cage, and is black 

 all over including the tail, but the under surface of the 

 primaries flecked with white. The thighs, rump, and wing- 

 coverts, which are white in T. pelagicus, are said to continue 

 quite black in T. branickii, even when fully adult, and they 

 are so depicted in f Der zoologische Garten/ xxxv. Jahrgang, 

 1894, by Dr. H. Bolau. Canon Tristram alludes to a pure 

 black Eagle, T. branickii, in the menagerie of Pere Heude 

 (Ibis, 1891, p. 471) * at Shanghai. 



Rupornis gracilis, Kidg. — Mr. Ridgway writes that R. gra- 

 cilis, inhabiting Cozumel Island, between Cuba and Yucatan, 

 is a strongly marked race of R. magnirostris, but in Proc. 

 L T .S. Nat. Mus. 1885, p. 94, he says it is similar to the 

 northern race of R. ruficauda (R. griseocauda, of which Ave 

 have 2) but smaller. 



* The latter informs me that in ' The Naturalist,' 1887, he has de- 

 scribed, under the name of Haliaetus niyer, an Eagle from Kamtschatka, 

 larger than H. albicilla, all black except the tail, which is pure white 

 and tapering.
