352 Lord Walden on the late Colonel TickelVs 
ferentiate individuals possessing them specifically from the 
type. For such examples the title of P. elegans (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. roseus £; nor is the 
throat greyish white. The back in P. Solaris $ is strongly 
coloured with olive-green ; in P. roseus 2 the green shade 
is much less marked. The bird depicted by Mr. Gould as 
P. Solaris $ (B. As. pt. i.), is clearly P. brevirostris 2 • 
P. roseus $ is figured and described by Colonel Tickell 
from a Tenasserim example. The uropygium and upper tail- 
coverts are described as being “ pure brilliant scarletP 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 <$ $ , 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.
