Report of Curator, Zoological Department. 



The only donations I have to acknowledge on the occasion of the present 

 meeting, are as follow : —

 Ursus isabellinus, Horsfield, v. syriacus, Hemprich and Ehrenberg. Of 

 several skins received, at various times, of this chiefly trans-Himalayan Bear, 

 the present specimen is the first that could be properly mounted as a stuffed 

 specimen.

 Lizard of the Tenasserim provinces, Platydactylus gecko, (Lin.) 



3. From E. Lindstedt, Esq. A large specimen of Dipsas trigonatus, Schnei-

Supplementary Report. 



The group selected for exhibition this evening is that of the BucerotidfS, 

 or Hornbills, with certain genera allied to them : and I have the pleasure to 

 call attention to a particularly fine series of these remarkable birds. The 

 following are the species now mounted in the Society's Museum ; which I 

 shall endeavour, as far as appears practicable, to arrange into minor groups. 



Firstly, a conspicuous series presents itself of species, amongst which the 

 casque attains its maximum of development ; being in particular well 

 elevated posteriorly, where it rises abruptly from the forehead, and generally 

 protrudes backward over it (instead of rising and gradually sloping forward 

 from the middle of the forehead, as in various other species). The sexes 



i 



resemble each other, black and white — save in one remarkable exception — 

 being the only colours of the plumage : and the medial portion of the throat 

 (more or loss broad) is well clad with feathers. 



At the head of this series range two remarkable species, both for size and 

 for the peculiar form of the casque, which is altogether different in the two :
