Subgenera Cooperastur and Urospizias. 259 



as " Section A " in the summary of this subgenus given in 

 the "^ Exotic Ornithology/ p. 170. 



Messrs. Salvin and Godman's specimen of C. poliogaster 

 agrees with Mr. Sharpens description of the type in the 

 Leyden Museum, with the following exceptions : — The wing- 

 coverts are not "darker'^ than the back, though they are 

 somewhat browner, as are also the primaries and secondaries ; 

 but the tertials are rather more slaty, like the scapulars ; 

 there is no tint of rufous on, or adjacent to, the shafts of the 

 wing- and tail-feathers ; the first primary has one white bar 

 on the inner web, and the other primaries have two such 

 bars ; the flanks, abdomen, and under tail-coverts are white, 

 like the throat; but the upper breast and the thighs are 

 slightly tinged with grey. 



Next to C. poliogaster, the scarcest species of the subgenus 

 is C. pectoralis, a specimen of which has also been recently 

 added to the collection of Messrs. Salvin and Godman ; this 

 example is a fine adult female from Sarayacu, in Ecuador ; the 

 following are its principal measurements : —

The Norwich Museum has lately been indebted to the good 

 ofiBces of the Rev. Canon Tristram for the opportunity of 

 acquiring an immature specimen of Urospizias alhigiilaris 

 (G. R. Gray), which was obtained at Makira harbour, 

 San Christoval island, in the Solomon group, by Lieut. 

 Richards, R.N. 



This specimen, which was killed on 27th August 1878, is 

 in immature plumage, with the exception of a few feathers of 

 the adult dress, which are apparent both on the upper and 

 under surface, and which suffice to identify it satisfactorily 

 with U. albigularis, the type specimen of which was also 

 obtained in the island of San Christoval. 



The immature plumage of this species has not, I believe, 

 been hitherto described; and the following particulars and 

 accompanying figure (Plate VIII.) of the specimen in the
