small flocks like B. albirostris, and I believe the members generally of the 

 section with which we commenced. Whether others of the present series 

 live also in pairs is worthy of observation. We have specimens of male, 

 female, and young, from Chyebassa ; presented by Capt. Tickell. 



The next has no casque, but merely a sharp edge to the upper mandible, 

 which is broad at base with an obtuse angle on each side. In XIII, 394, 

 I remarked its affinity for the African B. limbatus and B. flavirostris of 

 Ruppell; but have not now the opportunity of consulting that author's 

 publications. 



10. B. gingalensis, Shaw : B. bengalensis, Gray. Size small : colour dusky- 

 grey, paler and tinged with rufous below, especially on the under tail-coverts : 

 a slight whitish supercilium : wing-feathers narrowly edged with pale fulvous : 

 the primaries and all but the middle tail-feathers white-tipped. Bill amber- 

 yellow. Throat feathered along the median line only. Inhabits Malabar 

 and Ceylon. Specimen from Ceylon, presented by Lord Arthur Hay. 



The next has a low keel-shaped ridge, sloping off to the front ; but is 

 nevertheless somewhat allied to the last. Its throat is naked, or in the 

 young merely shows two single rows of ill developed feathers along the 

 middle. 



11. B. carinatus, nobis, XV, 187- Size moderate, or that of B. pica. 

 Colour green-glossed black, with the basal two-thirds of the tail drab- 

 coloured, the wing-feathers slightly margined paler : head fully crested. Bill 

 black, in the one sex, which seems always to have the abdominal region pale ; 

 in the other, yellowish-white, with black along the summit of the casque 

 nearly to the end, and also occupying the basal <wo-thirds of the lower 

 mandible, and the tomise of the upper one. A young specimen is quite 

 similar to the adults in plumage, but has no trace of casque, and the bill is 

 nigrescent with a whitish ridge and tip. Inhabits the Malayan peninsula ; 

 and the pair set up were procured at Malacca, and presented by the Rev. F. 

 J. Lindstedt : another pair, presented by Mr. E. Lindstedt, is preserved for 

 the Hon'ble Company's museum ; and I have seen several others. 



That which next follows has but a low slight casque, continued (as usual) 

 along the basal two-thirds of the upper mandible, and then sloping off to 

 the front ; but is very remarkable for the great development of the feathers 

 that impend the nostrils, which have stiff hair-like disunited webs, and reach 

 forward beyond the truncated extremity of the casque; the frontal feathers 

 being also moderately long and erect, and the whole, with the lengthened 

 occipital plumes, forming a showy ornament.
