352 Lord Walden on the lute Colonel Tickell's 



ferentiate individuals possessing them specifically from the 

 type. For such examples the title of P. e/c;$rGn* (McClell.), 

 founded on an Assam bird, has been adopted by Mr. Hume 

 and others. Burman and Assam birds, however, occur with 

 the middle pair typically coloured (that is, entirely black), 

 while in Darjeeling birds both varieties are to be met with. 

 Colonel Tickell figures and describes an example from Sing- 

 bhoom, Bengal, with the outer webs of the middle pair of rec- 

 trices red, as in so-called P. elegans. P. speciosus being a 

 widely spread and dominant species, exhibits that tendency 

 to vary usual among species occupying wide areas. 



The female of Pericrocotus roseus is correctly, and for the 

 first time, figured, but inaccurately described as only differ- 

 ing from P. Solaris ? by having the head no darker than 

 the back. In P. Solaris $ the ashy upper surface is dark 

 leaden, as in the male, the under plumage being bright pure 

 yellow, and not pallid yellow as in P. rosens $ ; nor is tlie 

 throat greyish white. The back in P. Solaris $ is strongly 

 coloured with olive-green ; in P. roseus $ the green shade 

 is much less marked. The bird depicted by Mr. Gould as 

 P. Solaris $ (B. As. pt. i.), is clearly P. brevirostris $ . 



P. roseus q is figured and described by Colonel Tickell 

 from a Teuasserim example. The uropygium and upper tail- 

 coverts aire described as being '' pure brilliant searlet.^^ This 

 is certainly the case with all Burman and Assam birds I have 

 seen. But is it so in typical Bengal and other Indian indi- 

 viduals ? These last I have never met with varying from the 

 description given by Jerdon (B. Ind. i. p. 422) — "rump 

 tinged with rosy." 



Lanius hypoleucus, Blyth [collurioides, Less,), from Tenas- 

 serim, is figured ; and so also, among the Dicruridse, is Di- 

 crurus balicassius, apud Tickell {annectens, Hodgs.), and Chibia 

 hottentata ( Criniger splendens, Tickell) . Examples of Hemipus 

 picatus S ? , from Ye, Tenasserim, are figured ; and this 

 species seems to be the only one found in Burma, unless the 

 Mergui bird, included by Blyth (Cat. B. Burma, No. 407), 

 was correctly identified as being H. obscurus.
