Accipiter etorqnes, part., Sclat., Proc. Zool. Soc, 1877, p. 109, No. 45 (young specimen). 



[No. 253. Male, from Wanumbai.] 



This bird is young. 



I have found in the museums of Leyden and Berlin two specimens which are very 

 much like my Urospizias spilothorax ; but they have only a few longitudinal dark spots 

 on the lower part of the breast, showing that these spots are not a permanent character, 

 and that my Urospizias spilothorax represents only a stage of Urospizias poliocephalus. 



4. Microglossia aterrimus, Gm. 



Microglossus aterrimus (Gm.) : Salvad., Proc. Zool. Soc, 1878, p. 92. 



[No. 206. "Wokan. Male. Eyes black ; cheek-membrane red. Stomach contained 

 many of the insides of kernels of nuts. This was shot on the top of one of the highest 

 trees. Only one seen at the time.] 



I have seen many specimens from the Arrou Islands, and these are in general much 

 smaller than those from New Guinea ; and I think that the type of Psittacus alecto, 

 Temni., which I have seen in the Museum of Leyden, must have come from the Arrou 

 Islands. 1 I do not think that there is more than one species of the genus Microglossus. 



5. Cyclopsittacus melanogenys, Rosenb.

Cyclopsittacus melanogenys, Salvad., Ann. Mus. Civ. Gen., vol. x. p. 29, sp. 33 (1877); Proc. 

 Zool. Soc, 1878, p. 92. 



[No. 207. Wokan. Female. Eyes black ; legs with a greenish tinge. 



1 The specimen in the Berlin Museum, which has been regarded as a second one of Microglossus alcdo looks 

 smaller than the New Guinea specimens from having had the primaries cut off.
