‘614 MR. P. L. SCLATER ON THE {June 27, 
y- Species Asiaticee. 
14. CHEUTURA SYLVATICA. 
Acanthylis sylvatica, Tickell, J. A. S. B. xv. 284; Jerdon, B. 
Ind. i. p. 170. 
Supra nigra @eneo nitens; uropygio albo; gula, genis et pect. 
pallide griseis, lateraliter in nigrum transeuntibus : ventre et 
erisso pure albis : long. tota 4°25, ale 5:0, caud@ 1°5 (Jerdon). 
Hab. Central India (Tickell) ; Darjeeling (Tickell) ; Nagpore 
(Jerdon). 
I have never met with examples of this species. Strange to say, I 
do not believe any museum in Europe contains it. Dr. Jerdon says, 
* An allied species is 4. lewcopygialis, Blyth, from Penang, differing 
from our bird in having the shafts of the tail-feathers much stronger, 
more resembling those of 4. gigantea, whilst in our species the tail- 
feathers more resemble those of 4. caudacuta. The Penang bird is 
black beneath, and is thus more normally coloured for a Swift.””— 
Jerdon, l. c. 
15. CH#TURA CORACINA. 
Cypselus coracinus, Mill. Mus. Lugd. 
Acanthylis coracina, Bp. Consp. p. 64 (1858). 
A. leucopygialis, Blyth, J. A. S. B. xviii. p. 809 (1858). 
Nigra ; corpore eneo-nitente ; tectricibus caud@é protractis, griseo- 
lacteis, rachide nigricante : long. tota 4°6, ale 5:2, caude 1:9. 
Hab. Borneo and Sumatra (Mus. Lugd.); Labuan (Motley) ; 
Penang, common (Blyth). 
I have seen examples of this species in the Leyden Museum, and 
in Mr. Dillwyn’s collection from Labuan. Mr. Blyth’s species is, 
no doubt, the same. 
Genus 2. CypsELOIDEs. 
Cypseloides, Streubel, Isis, 1848, p. 366. Type C. fumigatus. 
Nephecetes, Baird, B. N. Am. p. 142 (1860). Type C. niger. 
I think, although it is not a very easy question to decide, that the 
name Oypseloides, given by Streubel as an alternative to Hemiproene, 
in his article in the ‘Isis,’ before referred to, has claims to be used 
as a generic appellation for Cypselus fumigatus, from which Nephe- 
cetes (Baird) is hardly sufficiently different for separation. The 
form in fact is simply Chetura without the tail-spines. 
a. Cypseloides. 
1. CYPSELOIDES SENEX. 
Cypselus senex, Temm. Pl. Col. 397. 
Hemiprocne temminckii, Streubel, Isis, 1848, p. 368. 
Fusco-niger, capitis plumis anguste cinereo lineolatis, et rachidi- 
bus obsolete nigris ; cauda vix rotundata: long. tota 7-0, ale 
7'0, caude 2°5, tarsi 0°7.
