tion of both mandibles dark reddish-brown laterally, with a series 

 of narrow, transverse, whitish ridges, nearly similar to those of B. 

 cassidix ; the casque is scarcely elevated above the outline of the rest 

 of the upper mandible, but is broad and flat above, having a series 

 of narrow transverse whitish plaits, the intervals between which 

 are nearly filled up with a brownish substance, so that the profile 

 is almost even, and towards the front is worn quite so. As compared 

 with Labillardiere's figure of B. rujicollis, the casque of the present 

 species is less elevated, the plaits are much narrower and closer, and 

 do not reach so far as half way along the mandible; the ridges on 

 the sides of the bill itself afford another distinction from both that 

 species and the next, and approximate the present one to B. cassidix. 

 Length above three feet, of the wing nineteen inches, and tail ten 

 inches and a half; bill to gape seven inches and a half, and with 

 casque three inches high, the latter nearly two inches broad. Inhabits 

 Sylhet and the Tenasserim provinces. 



B. plicatus (?), Shaw ; B. subruftcollis, Nobis, ante, p. 177- En- 

 tirely resembles the last species in its plumage, having the sides of the 

 head and neck (in the male) more or less deeply tinged with golden-saf- 

 fron : but the size is much inferior, though the wings and tail being pro- 

 portionally longer, the difference in actual admeasurements is not great, 

 though that of the weight would be considerable; the casque is also 

 much more elevate and highly convex, instead of being flattened 

 above; the plaits on it more resembling those of B. rujicollis, except 

 that they are considerably more raised than in that species, though 

 far less so than in cassidix, and the foremost incline close over the bill 

 as in rujicollis ; there are also, as in rujicollis, no lateral transverse 

 ridges at the basal part of the mandibles, which is a further distinction 

 from cassidix and (presumed) pucoran. Length about thirty-two in- 

 ches, of wing sixteen and a half, and tail nine and a half; bill to gape 

 six and a half, and with its casque nearly three inches high, of which 

 the latter occupies a full inch ; it is also broad behind, becoming gra- 

 dually narrower to the front, whereas that of pucoran (?) is much 

 more uniform in its breadth throughout. Likewise an inhabitant of 

 the Tenasserim provinces, where apparently very common. 



This would seem to be the B. plicatus of Shaw, said to inhabit 

 Ceylon, which I much doubt; and I certainly do not believe that it
