214 Mr. J. H. Gurney’s Notes on 
length of the crest in this specimen as “ about two and a 
quarter inches.” I made it a trifle less, viz. 2:1. 
As I have already mentioned, I have only had an oppor- 
tunity of examining three specimens of P. ptilorhynchus from 
the Philippine Islands. Of these, one is an immature bird in 
the Derby Museum at Liverpool, respecting which I have the 
following note :—“ Breast cinnamon, with strong dark shaft- 
marks; abdomen and thighs cinnamon, crossed with white ; 
mantle dark brown, with the feathers slightly edged with 
light brown ; length of crest 1:2.” 
Another is the female from Butuan, in the island of Min- 
danao, which was described by the late Lord Tweeddale in 
the P. Z. S. for 1877, p. 821; this specimen, which is in pro- 
cess of change from immature to adult dress, has a crest mea- 
suring 1:1 in length. 
The third, which is preserved in the Norwich Museum, has 
a crest of very similar dimensions, measuring 1:2. In this 
specimen the upper surface, wings, and tail resemble the 
darker-complexioned Indian examples; the grey on the head 
is confined to the sides only, and is tinged with brown on 
the ear-coverts ; the throat shows the gular and two malar 
stripes distinctly marked in black, the interspaces being buffy 
white with narrow dark shaft-marks to each feather ; the fea- 
thers of the upper breast are brownish black, with cmnamon- 
brown bases and edges; the remaining underparts, including 
the under wing-coverts, are cinnamon-brown, varying a little 
in the richness of the tint, and with narrow dark shaft-marks 
on the feathers of the lower breast, which are also transversely 
marked with very narrow bars of two shades of brown; the 
front tertial feathers are narrowly barred and also tipped with 
brownish white, and the under tail-coverts more broadly so. 
It may be desirable to add a few words as to the dimen- 
sions to which P. ptilorhynchus attains in various localities. 
I have notes of nineteen Indian specimens measured by myself. 
Of these the lowest wing-measurement is 15:4 inches, in one 
specimen ; the wing measures between 15°4 and 16 in six, 
between 16 and 17 in eight, between 17 and 18 in three, and 
above 18 (viz. 18°1) inone. The smallest length of the tarsus
