approximates very closely to this remarkable Himalayan bird, 

 which seeks its food along the border of the snow-line. 



Osmotrero7i fiavogularis, nobis (J. A. S. xxvi. p. 225, xxxi. 

 p. 334). This is identical with 0. pompadora apud Bonaparte 

 (Iconographie des Pigeons), and with Fm<?^o aromaticasipudi Selby, 

 in the volume of " Pigeons" in the ' Naturalist^s Library.^ Spke- 

 nocercus cantillans, nobis {passim), figured also by the late Prince 

 of Canino, is merely S. sphcenura, the common Kokhela of the 

 Himalaya, after moulting in captivity, when the gi'een of its 

 plumage is more or less completely replaced by delicate pearl- 

 grey, as was long ago remarked by my friend Captain Thomas 

 Hutton, of Masuri. 



The Derby Museum of Liverpool is rich in Philippine birds 

 (collected by Mr. Cuming), and also in the avifauna of the 

 Indonesian archipelago. I went carefully through its collec- 

 tions in every class, and took many notes of the birds of S.E. 

 Asia and its islands, which I transmitted to my friend I)r. Jerdon. 

 A few, apparently undescribed, species may be here noticed ; and 

 a further selection of my memoranda taken chiefly there, and 

 some in the museum of the Royal Institution of that borough. 



Cypselus acuticauda, nobis, n.s. Specimen marked from "Nipal. 

 Length 7| in,; extent of wings 20 in.;" closed wing 6| in. 

 Size and proportions of C. apus; the tail forked to the depth of 

 an inch, and much more sharply acuminate than in C. apus. 

 Entire upper parts, with the lower tail-coverts, deep black, having 

 a slight metallic gloss ; each feather of the lower parts (excepting 

 the lower tail-coverts) margined with dull white; throat white, 

 with a black medial streak to each feather; claws more or less 

 whitish. From C. leuconyx, nobis, of the N.W. Himalaya 

 chiefly, this species difi'ers in the absence of the white band 

 crossing the rump. The true C. apus has been received from 

 Afghanistan. 



Dendrocitta himalayensis, nobis. This is the common Hima- 

 layan bird which has hitherto been referred to D. sinensis 

 (Gmel.). The latter is well distinguished from it, having a 

 comparatively short tail, the middle feathers of which are black 

 throughout ; brightly glossed margins to the wing-feathers ; 

 and the white wing-spot is much less developed. The two
