142 Lieut. Wardlaw Kamsay’s Synopsis 
that adult birds from Tipperah and Arakan will be found to 
be identical with those from Assam^ especially as Blytlds cor¬ 
rected description of his Orthorhinus hypoleucus (J. A. S. B. 
xiv. p. 597) agrees with adult specimens from Assam. Un¬ 
fortunately the specimen from which he took this description 
was not brought home by Colonel Godwin-AusteU; and is_, I 
presume^ still in the Calcutta Museum. 
Another variety (P. tickelli, Blyth, apud Tickell, Ibis, 
1863, p. 113), occurs in Tenasserim, having been obtained on 
the mountains of that province by Colonel Tickell in 1855. 
Mr. Blyth, however (J. A. S. B. 1855, p. 273), treated this spe¬ 
cimen as merely a variety of P. hypoleucus, and thought it 
probable that it might be only a particularly fine adult of that 
species. As this specimen (which I have now before me) is, like 
so many of the specimens from the Calcutta Museum, so much 
faded as to be almost useless for describing, I give Blyth'^s 
own words (/. c.) :—Specimen remarkable for having narrow 
white mesial streaks to the feathers of the nape, chiefly 
towards the sides of the nape, which we can perceive no trace 
of in Arakan specimens ; and similar well-defined but wider 
streaks on the dark ash-coloured sides of the breast, which 
are little more than indicated in the Arakan specimens under 
examination.'’"’ Air. A. O. Hume has lately (S. E. v. p. 32) 
proposed the name tickelli ” for this supposed species. It 
was known to Col. Tickell (Ibis, 1863, p. 113) as P. tickellii, 
Blyth, but no reference is given.
