2. Capt. S. R. Tickell, Maulmein. A collection of bird-skins, from 

 the mountainous interior of the Tenasserim provinces. This collection 

 contains several new species ; and among them is the female of apparently 

 an undescribed Hornbill. 



Buceros Tickelli, nobis, n. s. Length 25 or 26 in. ; of wing 12 in. ; 

 and tail 1 1 in. Bill A\ in. from forehead, and 2 in. in greatest vertical 

 depth, at \ of its length from base ; the basal half of the upper mandible 

 gibbous, or pinched up (as it were) into a sharp keel, which descends more 

 abruptly upon the forehead (where concealed by the erect frontal feathers), 

 and slopes evenly forwards till it disappears, at about § of the length of 

 the bill from base. Occipital crest ample ; the feathers open-webbed, and 

 with those of the crown fuscous-brown with narrow pale mesial line to 

 each: upper-parts uniform dark fuscous-brown, with, a slight gloss of 

 green ; the middle pair of tail-feathers coloured like the back, but the 

 rest much darker, or glossy green-black, — as are likewise the primaries 

 and secondaries, which are more or less margined with brown (nearly as 

 in B. galeritus) : some pale feathers at base of the winglet ; and the 

 3rd to the 7th primaries (inclusive) have their outer web emarginated 

 successively further from the base, the commencement of the emarginated 

 portion of each being somewhat broadly edged with fulvous-white : pri- 

 maries and rectrices tipped with dull white, more or less speckled with 

 dusky : the entire under-parts dull rusty -isabelline, except the feathers 

 at the base of the lower mandible, which are coloured like those of the 

 crown : in texture the feathers of the lower-parts are loose and open- 

 webbed, especially on the throat and front of neck. Bill intermixed 

 dusky and yellowish-white, passing to yellow on the imperfectly deve- 

 loped casque. 



This conspicuously distinct species from any other Hornbill which we 

 have seen, was found by Capt. Tickell " confined to the great hills (the 

 continuation of the Himalaya and Yo-ma-tsung) which run JN". and S. 

 through the Tenasserim provinces, and form the back-bone of the Malayan 

 peninsula. They are wild and wary, and keep to the summits of such 

 colossal trees that it is no wonder Mr. Barbe and other collectors in this 

 country never procured a specimen. I believe, however, that no European 

 has ever been into those jungles besides myself. This Hornbill and B. 

 pusaran have a steady even flight. All the others I have seen, viz. cava- 

 tus, albirostris, nipalensis, pica, and birostris, proceed with those 

 singular flappings and sailings, so peculiar to this genus : and it is strange 

 that tfyese two species should offer so marked a distinction."* 



* Capt. Tickell has subsequently forwarded a more elaborate description of this 

 Hornbill, for publication in the Society's Journal.
