SCISSORS-BILL. \ 



At Tavoy the sheer-water, or scissors-bill, is frequently 

 seen cleaving the water with its curious bill, the upper 

 mandible of which is much shorter than the lower. It 

 has never been noticed among the collections of birds 

 sent to Calcutta, either from these Provinces or Arracan. 

 A specimen that I examined differed in no important res- 

 pect from the European species. 

 Rhynchops nigra.

TROPIC-BIRD. 



A single species of tropic-bird, or boatswain-bird, with its 

 two long tail feathers, is known to inhabit the Bay of Ben- 

 gal ; and it is rather remarkable that while it differs from 

 the species found near the Mauritius on the west, Ph 

 candicus ; and from the species found towards Australia 

 on the east, Ph. phamicuru* ; it is identical with the 

 common tropic-bird in the Atlantic Ocean. 

 Phceton athereus.
