44 A FIRST LIST OF THE 



the same are generally, but not always, noticeable on the whole 

 of the feathers of the head and the nape. The inner webs of 

 the quills are hair brown, and the inner halves of these are notice- 

 ably paler than the halves next the shafts. The exterior tail 

 feathers are the longest, and exceed the central ones by a full 

 inch. The sides of the head and neck are of much the same color 

 as the nape, which is generally slightly paler than the crown, 

 and more or less conspicuously, though still very narrowly, fringed 

 paler at the tips. The chin and the centre of the throat is pure 

 white or brownish white ; the feathers faintly brown-shafted. 

 The extent of the white on the throat varies considerably in 

 different specimens ; the chin in some birds is quite brown. The 

 whole of the breast, abdomen, lower tail coverts and lower 

 wing coverts, except the greater ones, are in some blackish 

 brown, in others a hair, umber, or even sepia brown, each 

 feather fringed at the tip with white. The greater lower coverts, 

 which also show traces of similar tippings and the under surface 

 of the quills and rectrices, are a more or less glossy grey 

 brown. 



In good specimens of adults the back, tail, and shoulder of 

 the wing are almost quite black, and exhibit a decided greenish 

 gloss. 



I here note that leuconyx of Blyth is a very different bird 

 indeed. It is not, I think, as Dr. Sclater remarks, that the white 

 bar on the rump is narrower, and that there is much less white 

 on the throat, because these are points that vary in individuals of 

 both species ; but leuconyx is altogether a much smaller bird : 

 Length, 5" 8 to 6 as a maximum; wing, 5 - 9 to 6*2 also as a 

 maximum ; the under surface with much narrower and less- 

 marked white fringes than in pacijicm ; and lastly, the whole of 

 the feet (not the claws, as has been erroneously stated) very 

 pale-colored, almost albescent in some specimens. This is a 

 thoroughly good species, and no one, I venture to say, who has 

 examined good specimens, would ever doubt it.

 group, viz., opus and acuticatula, vide Vol. II, p. 156. 



102 Ms.— Cypselus infumatus, Sclater. 



Mr. Oates says : " This species is very common near all villages, 

 and in fact wherever the Borassus (palm) is found. I fancy it 

 breeds about the middle of May. A male measured — 



"Length, 5-15; expanse, 11*1; tail, from vent, 2 '45 ; wing, 

 4'6; bill, from gape, 0*54; tarsus, 0*33. 



"The bill and feet are black; the claws, dark brown. The 

 eyelids, plumbeous ; irides, brown." 



This is the species which Dr. Jerdon described as Cypselus 

 teetorum from specimens obtained by Major Godwin- Austen on
