176 MR. J. GOULD’S DESCRIPTION OF A NEW SPECIES 
minck has altered its specific name, and has designated it as the Eur. Corydon. 
M. Lesson has remarked on the extraordinary breadth and strength of its bill, on the 
dilatation and swelling posteriorly of the margins of this organ in such a manner as to 
render the lower mandible entirely thin at its base, on the keel and the uniform con- 
vexity of the bill, on the rounded and indistinct nostrils in some degree hidden by the 
hairs and the small feathers of the front, on the naked circle surrounding the eyes, &c., 
as on characters sufficient to distinguish it as the type of a subgenus, for which he pro- 
poses the name of Corydon; the species being designated by him Corydon Temminckii?. 
It would, however, be preferable to retain the original specific name, and to call the 
bird Corydon Sumatranus. 
The third addition to the genus to which I have alluded is that by MM. Lesson and 
Garnot, who have figured and described in their beautiful work, the Zoological Portion 
of the ‘ Voyage de la Coquille’?, a bird obtained by M. Lesson in New Guinea, to 
which they have given the name of Hurylaimus Blainvillii. As I have had no oppor- 
tunity of examining this bird, and am acquainted with it only through the medium of 
the figure published in the work just quoted, I must speak with diffidence respecting it: 
but I cannot venture to regard it as really a Eurylaimus, possessing as it evidently does 
characters at variance with all others of that group. Its lengthened and forked tail, its 
feeble tarsi, and its narrow bill furnished with stiff bristles, appear to indicate its natural 
position to be among the true Flycatchers. 
There remain then, in the defined genus Eurylaimus, only the Eur. Horsfieldii, Temm.°, 
the type of the genus, and described as such by Dr. Horsfield in the ‘Transactions of the 
Linnean Society’ under the name of Eur. Javanicus®:—the Eur. ochromalus, Rafil.®, 
of which Eur. cucullatus, Temm.’, is a synonym :—and the species for which I propose 
the name of Eur. lunatus. The latter presents, it is true, some minute differences from 
the two previously mentioned birds ; but as these differences consist principally in the 
filamentous termination of the primary and tail-feathers, and in the singular crescent- 
shaped row of silvery feathers which adorns the neck of the male, they are by no means 
likely to exercise any influence over the habits of the bird, which may consequently be 
placed with the true Eurylaimi. It may be thus characterized : 
EvuryLAIMUS LUNATUS. 
Eur. capite cristato ; cristd genisque brunneis ; fascid supraciliari nigrd ; guld cinerascente ; 
collo, interscapulio, pectore, abdomineque cerulescenti-cinereis ; tergo uropygioque cas-

° Dr. Horsfield having withdrawn the cJaim of priority in naming this species, and having allowed another 
name to be substituted for that originally given, the one substituted by M. Temminck and allowed by Dr. Hors- 
field will probably be generally adopted.
