312 Notices and Descriptions of various New [No. 172. 



Arraean, which, until I had obtained a good series of both, I declined 

 to venture on distinguishing, but which I shall now designate 



C. affinis, nobis. In this, while the general characters and colouring 

 are the same as in C. nasutus, the bill is invariably much smaller and 

 flatter, as in the restricted Eurylaimi, but the nostrils are placed for- 

 ward as in the other. The general dimensions are also less, the usual 

 length of wing in C. affinis being three inches and a half, rarely three 

 and five-eighths, and the middle tail-feathers three inches ; in C. nasutus 

 the wing measures three and seven-eighths to four inches, and the tail, 

 three and five-eighths to three and three-quarters. C. affinis has also, 

 constantly, an oblong red spot margining the tip of the outer web of 

 two of its tertiaries, and a third margining the inner web of the up- 

 permost tertiary : in what appear to be the females, the latter spot is 

 red as in the supposed males, while the former are white : these spots 

 do not occur in C. nasutus. Lastly, the white upon the tail is more 

 developed in C. affinis, and placed nearer the tips of the feathers: a 

 white spot at the base of the inner primaries is also larger and more 

 conspicuously shewn. 



If the affinity of the Eurylaimi with the South American Pipridce 

 admit of doubt, the question would seem to turn on the relationship of 

 the former for Calyptomena ; for this Malayan genus appears truly to 

 approximate to Pipra and more especially to Rupicola.* Mr. Swainson 

 distinguishes two species of Calyptomena (Lardner's Cyclopaedia, ' Me- 

 nageries', p. 296), as C. Rafflesii and C. caudacuta ; and he assigns 

 India as the habitat of the latter, erroneously unless by that word he 

 means vaguely " the East Indies", a term now rapidly and properly fall- 

 ing into disuse. Notwithstanding, however, the difference in the form of 

 the tail, and which is not so great as Mr. Swainson represents it, I feel 

 satisfied that his C. caudacuta is the young of C. viridis, Raffles, who 

 states that " the female does not differ in appearance from the male." 

 The tail is a little graduated in these presumed young birds, but I have 

 never been able to recognise the pointed form of the feathers represent- 

 ed by Swainson, nor the difference of size which he indicates ; indeed 



* Another Malayan genus with syndactyle feet, and which I have not yet seen, 

 is the Crataionyx of Eyton, P. Z. S. 1839, p. 104: and to judge from the brief Latin 

 definitions of his two species, Cr. flavus and Cr. ater, 1 think there is every reason 

 to suppose them to be the sexes merely of the same species.
