sions, relative length of wings and tail, wing-formula, and 
shape of bill with Tribura luteoventris, Hodgs. The type of 
the former, in the Museum of the Jardin des Plantes in Paris, 
agrees also in colour; but the types of the latter, in Man- 
delli’s collection, present slight variations. One skin has 
spots on the throat, and the other traces of slate-grey on the 
breast. I imagine these only to be seasonal changes; but 
they may prove hereafter to be specific characters, as Blyth 
suspected to be the case in his nearly allied Dumeticola 
thoracica. 
Phyllopneuste trochilus, Hodgson, Gray’s Zool. Mise. p. 82 
(1844). The type, formerly in the India Museum, and now in 
the British Museum, is a skin of Phylloscopus lugubris, Blyth. 
Abrornis zanthogaster, Hodgson, Gray’s Zool. Mise. p. 82 
(1844). This species was incorrectly identified by Horsfield 
and Moore (Cat. E.I. Co. Mus. i. p. 337) with Phylloscopus 
lugubris, Blyth. The types, formerly in the India Museum, 
and now in the British Museum, are skins of Phylloscopus 
affinis, Tickell. 
Abrornis tenuiceps, Hodgs. Gray’s Zool. Misc. p. 82 (1844). 
The type, in the British Museum, is a skin of Phylloscopus 
humei (Brooks) ; but as Hodgson appears nowhere to have 
given any description of his species, Brooks’s name will stand, 
according to the British-Association Rules. There are also 
skins of this species in the British Museum labelled P. mo- 
destus in Blyth’s handwriting. 
Abrornis chloronotus, Hodgs. MS. Drawings (in the Brit. 
Mus.) of Birds of Nepal, Passeres, pl. 57, no. 839, undoubt- 
edly represents Phylloscopus proregulus (Pall.), without the 
grey on the head and throat and without the white on the 
inside webs of the two outside tail-feathers characteristic of 
P. maculipennis, Blyth. On the other hand, in the same 
MS. work, App. pl. 45, also no. 839, are two figures un- 
doubtedly representing Blyth’s species. In the British Mu- 
seum both species are represented amongst Hodgson’s types, 
both being numbered ‘‘839.” Hodgson does not appear ever 
to have described his species, but catalogues it in Gray’s
