tail, retain in the adult the same colouring as that of the young of 

 H. cheela; a phase of plumage which we have never seen among 

 the multitude of Bengal specimens of H. cheela examined, but 

 which is exhibited in the two now received from different parts of 

 Ceylon. A figure of a third specimen is given in a collection of 

 zoological drawings from Ceylon forwarded on inspection by Mr. J. A. 

 Moorgaart. In this the irides are represented pure white (as in 

 Poliornis teesa), whereas those of H. cheela are brilliant golden- 

 yellow. 



Spizaetus limnaetus, (Horsf.), var. cirrhatus et cristatel- 

 lus, auct., of peninsular India generally. Specimen rather small. 



Buceros pica, Scopoli. The common Pied Hornbill of Ceylon; 

 sent also by Mr. Layard. Identical with Indian specimens : and we 

 therefore consider B. violaceus, Shaw, apud Wagler (with four black 

 medial tail-feathers) to be merely a casual or occasional variety, more 

 especially as we have seen continental examples with the sub-medial 

 rectrices partly black. 



B. gingalensis, Shaw. Head of male. 



Cuculus Sonneratii, Latham. 



Malacocereus griseus, (Lath.), var. Resembling the species 

 of S. India, excepting that the head is concolorous with the rest of 

 the upper-parts. 



Grauculus javensis (? Horsfield). Sent also by Mr. Layard. 

 Differs from Gr. Macei of continental India in its considerably 

 smaller size, the wing measuring but 5^ in., with the rest in pro- 

 portion. 



Gallus Stanleyi, Gray. A fine hen. We had previously only a 

 pullet of this sex. 



Dromas ardeola, Payk., in immature plumage. An extremely 

 interesting specimen, as distinctly indicating the affinities of this (as 

 hitherto considered) anomalous and isolated genus. The plumage is 

 precisely that of a young Tern : and from all the details of outward 

 structure, it will be seen that this curious form is but an extraordinary 

 modification of the Tern type, just as Phcenicopterus is a most 

 singular modification of the type of Anserine. But the Gulls and 

 Terns, or Larid^e, are more nearly affined in their whole organization*
