374 BURMA, ITS PEOPLE A.\D PRODUCTIOXS. 



The author of this species is doubtful if it miiy not be identical with Rrgidoiilea 

 fuliiventer, God.-Aust., founded on a carbolized example in which the green and 

 yellow have been discharged or turned grey. Hume gives a caution on this point in 

 S.F. vi. p. 319 : "It is a curious fact, that you can manufacture cinereiventrw 

 (^Brachi/podius) or the Sumatran chalcoccphilus or any intermediate form to any extent 

 by the use of a little carbolic acid. When the colour is pure yellow, as at the tips 

 of the tail, the feathers come out icliite, as in these parts in chalcocephalus; but wherever 

 the peculiar olivaceous green prevails, there the feathers remain of the exact ash grey, 

 that we find in cinereiventris and chalcocephalus. The curious yellow green of 

 melanocephalus is in fact a combination of ash grey and pure yellow, and whether 

 species or local races, all that has happened in cinereiventris and chalcocephalus seems 

 to be that, for some reason, the skin has in places {cinereiventris) or wholly 

 [chalcocephalus) ceased to secrete the yellow pigmeut." 



A. XAXTHOscHisius, Hodg. Nipal. Sikkim. Arakan. 



sylviix-t;. 



Few of this group of warblers occur in India, and none have as yet been recorded 

 from Burma. 



MOTACILLINiE. 

 Jerdon divides them into Hill Wagtails, with rounded wings and the tcrtials not 

 lengthened, the true Wagtails with lengthened tertials and unstreaked plumage, 

 and the Titlarks, with streaked plumage. 



ITill WaijtaHs. 



Henicurus Leschknaulti, Vieill. 



Lord Walden remarks : — This Javan and Foocliow bird is stated by Mr. Hume 

 to have been obtained in the neighbourhood of I'ahpoon and at Meeta Myo. If the 

 identification is correct, an interesting fact. It may perhaps be II. frontalis. 



H. FRONTALIS, Blyth. Tenasserim south of Mergui. 



H. iMMACULATDS, Hodg. Khasi. Arakan. Pegu. Tenasserim. 



Hume doubts if this species ranges so far south as Tenasserim, but it is impro- 

 bable that Blyth assigned a habitat without cause. 



H. scHisTACEUs, Hodg. Arakan. Tenasserim. China. 



It is less common in Arakan than the last species. 



H. GUTTATUs, Gould. Khasi Hills. Arakan. 



H. iirFicAPiLLUs, Tern. Southern Tenasserim. 



A straggler from the south, and the rarest species there. 



Henicurus is an aberrant group, with affinities to Htjdrolata. Their plumage is 

 black and white, and they have pale fleshy-white legs. 



True Wagtails. 



MoTACiLLA LuzoNENsrs, Scop. Arakan. Pegu. Tenasserim. Andamans (?). 



[Toung-ngoo ( 7F. 7?.). The black-backed, white-faced species, is referred to 

 under the a))ove title. But strictly Sonnerat described the grey backed bird. While 

 Scopoli in his diagnosis, taken from Sonnerat, misquoted the description, and converted 

 the word "grey" into "black." The members of this section of the genus which 

 inhabit Luzon have not hitherto been examined, and it therefore remains quite 

 uncertain from what species Sonnerat described. It is not improbable that he did so 

 from an Indian example of M. dukhunensis.'\ 



M. DuKuiTNENSis, Sykcs. Martaban. Karen-ni. 



Both the last two species are cold weather visitants only. 



M. MEi.AxorE, Pallas. Arakan. Pegu. Tenasserim. Andamans. 



M. hoarula, Tem.
