blue green than yellow green ; and the tliroat-feathers appear to differ in their metallic glance 

 from those of the Sumatran race. The bill likewise is slenderer, and all the dimensions are 

 somewhat less. 



Brisson described this bird in the clearest language from a skin in Reaumur's collection, 

 to whom it was presented by M. de Vergene, who, according to Brisson, received it from 

 the Brazils. Upon Brisson's authority Gmelin founded its title braziUaua, and, although 

 geographically inappropriate, I prefer adhering to the law of priority. At some future time some 

 authoritative body of naturalists will have to agree upon those titles, of the older authors, which 

 ought to be expunged. Temminck's type was from Java. Mr. Blyth's JY. phaijrei was described 

 from an Arakan specimen. 



1 concur with Dr. Cabanis in placing this species in his genus Leptocoma. The female and 

 young plumage is unrecorded. It has not hitherto been found further north than Arakan, and 

 is unknown to the west in India proper.

" Frequents the tops of flowering trees, and has much the habits of a Bicceum. Female a 

 little duller-coloured than male ; generally seen in pairs. Irides dark red ; bill brown ; legs and 

 claws dirty greenish yellow." The slightness of the distinction described by Captain Beavan 

 between the sexes is interesting ; but the three specimens sent are those of males. When 

 compared with a Sumatran skin they appear less brightly and richly coloured. In the latter 

 bird the rufous of the breast and throat is deeper in tone and descends lower down ; it is separated 

 from the yellow of the abdominal region by a more trenchant line. In the Tenasserim spe- P.Z.S. 186G, 

 cimen the rufous dies away into the yeUow ; in them also the bill is decidedly longer, while in ^' 

 all the other dimensions they are inferior to the Sumatran bird. 



Brown figured and described this species, in his ' Illustrations,' from a specimen said to have 

 been from the " East Indies." Gmelin, in error, gave Ceylon as its habitat, although he founded 

 his M. singalensis on Brown's description and plate. Latliam fell into the same mistake ; and 

 hence in all the authors we find Ceylon recorded as the native country of Gmelin's species. 

 Temminck, fully aware that Gmelin had previously described it, gave it another name ; and 

 Mr. Blyth, in 1843, unconscious that it had been previously named, gave it as a new name the 

 one already used by Temminck. Mr. Blyth was the first author wlio referred the species to 

 Swainson's genus Anthreptes, instituted for the reception of Certhia malaccensis, Sco-p. , = Necta7inia 

 javanica, Horsf., and chiefly characterized by the stouter and straighter bill — with which species 

 it appears to me to be closely allied. Dr. Cabanis has, in the ' Museum Heineanum,' separated 

 it from Anthreptes, and made it the type of a new genus, Clialcoparia. 



Tippera is the most northern region from which this species has hitherto been recorded. It is
