346. Pitta nigricollis. 
Mr. Hodgson figures the egg as reddish-white with rufous 
specks. 
347,348, and 349. Hydrobata asiatica, H. cashmiriensis, 
and H. sordida; Gould, B. As. pt. xii. pis. 
I have lately seen a fine specimen of H. cashmiriensis in a 
Sikhim collection. May not this be the Cinclus aquations of 
Herr Badde from North-eastern Asia? Yw- »-<>• 
351. Petrocossyphus cyanus. 
The curious fact of a bird of this species attacking and 
devouring a luckless Phylloscopus trochilus has been noticed 
(Ibis, 1860, p. 139). I suspect that this is not more anomalous 
than Mr. Layard’s instance of a captive Megalcema zeylanica 
which evinced a similar predatory propensity (Ann. Mag. N. H. 
1854, xiii. p. 446). The Turdus ( Monticola ) erythroptera , 
G. It. Gray (P. Z. S. 1860, p. 350), from Gilolo, is no other 
than P. affinis, a variety of P. cyanus ! 
352. Oreocletes erythrogastra (Vigors); Gould, B. As. 
pt. xv. pi. 
I suspect that the name “ Rock-Thrush,” applied by Mr. 
Gould to this species, is not better suited to its habits than Mr. 
G. R. Gray’s generic appellation, the Oreoccetce being forest- 
birds, unlike the Petrocossyphi. The egg as figured by Mr. 
Hodgson is like that of an English Robin. 
355. Geocichla citrina (Lath.) ; “ Turdus albonotatus , 
Cuv.,” Pucheran. 
Temminck gives Java and Sumatra as habitats, but refers to 
G. rubecula, Gould, which has a deeper colouring. I kept a 
Thrush of this species for a long while in a cage; and it had a 
plaintive mellow song, somewhat Robin-like and little varied. 
356. Geocichla unicolor (Tickell); Merula unicolor , 
Gould, B. As. pt. x. pi. 
Mr. Gould states that I do not include this species in my 
f Catalogue of the Birds in the Asiatic Society’s Museum, 
Calcutta.’ It is no. 954 of that Catalogue! And he calls it 
the “ Afghan Thrush,” which is a misnomer, though it may
