212 Mr. J. H. Gurney’s Notes on 
the possession of Canon Tristram, to whose kindness I am 
indebted for an opportunity of examining it. This specimen 
much resembles the adult bird from Java described by Mr. 
Sharpe and figured by Prof. Schlegel*, to which I have 
already alluded ; it has, however, a shorter crest, measuring 
only 1:9; and the rufous on the sides of the neck and on the 
breast is less bright than is represented in that figure, from 
which it also differs in having the buffy white marks on the 
abdomen more in the form of bars, alternating with indistinct 
transverse bands of two shades of brown, and in the pale space 
across the centre of the tail being darker towards the tip of 
the tail than towards its base. I may add that a portion of 
the shaft of the rectrices passing through this pale space is 
white. 
A specimen very similar to this Bornean example has been 
kindly lent to me by Lieut. Wardlaw Ramsay, by whom it 
was recently received from the hill country of Western Su- 
matra; but this example has a crest measuring 2°3 inches in 
length, and is also remarkable for the unusual breadth of the 
dark subterminal bar on the tail, which measures 2°3 inches 
from its upper to its lower edge. 
Des Murs, at pl. 13 of his ‘ Iconographie Ornithologique,’ 
has figured the type specimen of Lesson’s “‘ Pernis torquatus,” 
and states that “le voyageur Duvaucel l’a rapporté au Mu- 
séum d’ Histoire Naturelle en Septembre 1821 de Sumatra.” 
Judging from Des Murs’s figure and description, this Sumatran 
specimen is an example of Pernis ptilorhynchus in the stage 
described by Mr. Sharpe as “ intermediate,” and, except for 
its somewhat longer crest, does not differ from many examples 
in a similar phase of plumage obtained in India. 
Another, more fulvous, but crestless Sumatran specimen 
has been figured by Miller and Schlegel in Temminck’s ‘ Ver- 
handelingen &c.,’ Aves, pl. 7: it is a young female, and is 
no. 6 in Professor Schlegel’s list of the birds of this species 
in his ‘Museum d’ Histoire Naturelle des Pays-Bays,’ Pernes, 
p- 3. Mr. Sharpe briefly describes this specimen, but does 
not mention that it was obtained in Sumatra.
