438 ON THE SPECIES OF BATRACIIOSTOMUS [1877. 



feathers broadly barred with green and purple, and overlapping, form a succession of regular 

 bands ; the bars on the under tail-coverts are broader and of a stronger purple tint. Uuder- 

 surface of wing white at the inner base of the primaries and secondaries, forming a narrow white 

 bar inside the wing ; a pure broad white crescentic collar on the lower nape, commencing low 

 down on the side of the neck. Bill yellow. Legs rich green. Irides red, and a bright crimson 



orbital skin. 



Length about 6 inches, wing 4 0, tail 3-1, tarsus 0-6. 

 Hah. Base of Mule-it range, Tenasserim. 

 P.Z.S.1877, This species (Avhich, while closely allied to, differs from C. xaiithorhynchus, Horsf, by having 



^■^^'' a broad white nuchal collar) was discovered by Mr. Ossian Limborg under the Mule-it range, 

 east of Moulmein, in January of the present year. 



BRACnTPTERTX BUXTONI, n. sp.

The rarity in our collections of examples representing the different members of the genus 



JhtfrarhostomHS in all their various states of plumage, the want of field-collectors' notes to 



elucidate the few that do exist, the variability and intricacy of the markings by which they are 



characterized, and consequent difficulty, more especially in the males (?), of conveying by mere 



description, and even by coloured drawings, an adequate conception of their distinctive external 



characters, have combined to retard our knowledge of the genus. 



P.Z.S.1877, The group was unknown to the older zoologists ; and Dr. Horsfield was the first naturalist 



P""*"^" who described (1820), and afterwards figured, one of its members, an inhabitant of Java— 



JJ. jnvensis. Temminck soon afterwards (1823) described and figured another species from 



Bencoolen, in Sumatra, obtained by Messrs. Diard and Duvaucel, probably under the auspices of 



Sir Stamford Raffles; and a few years later (1830) Vigors made known the giant form of Sumatra, 



B. auritiis, sent to England among the collections of Sir Stamford. In 1837 Mr. Gould added a 



fourth species, B. stellatus, describing it as inhabiting Java. Dr. Jerdon, in his Second 



Supplement to his 'Catalogue of the Birds of Southern India' (1845), announced the discovery
