satmatioribus. Long, alee 2'65, caudce 2'5, tarsi 0 95, rostri afronte 0'6, a 
rictu O' 75 me. 
Crown of head and nape ferruginous, lores, over and under the eye, pale 
pinkish isabelline, most of the feathers of the forehead, lores and supercilia 
with slight dusky tips, ear coverts pale rufous brown, also with dark tips, 
back of the neck isabelline, or pale brown, each feather with a large dusky 
spot, frequently confined to one web, mantle and tail brownish olive, all the 
rectrices except the centre ones with narrow pale tips, quills hair brown mar- 
gined with brownish olive externally, internally, like the lining of the wing, 
pale brown. Chin and upper throat pure white, remainder of lower parts 
isabelline, breast and sides of neck with large elongate dusky spots, flanks 
also spotted, but the spots are paler, abdomen unspotted. Bill dusky above, 
pale below, legs very pale coloured. 
This species differs from P. rufeeps, Swains., and P. Tickelli, Blyth, (J . 
A. S. B., 1859, Yol. xxviii, p. 414 ; = P. subocliraceum, Swinhoe, A. and 
M. N. II. , April, 1871, p. 257), by having the neck spotted all round and by 
the spots in front being much deeper and darker. In size it resembles P . 
Tickelli , being smaller than P. rufeeps. It may perhaps be the new species 
from the Khasi hills mentioned by Dr. Jerdon in Birds of India, II, p. 28. 
A single specimen has been sent to me for identification by Mr. Mandelli, 
after whom I have named it. 
620. Mixla cdteeea, (Blyth). 
The type of this species is a very dull coloured grey specimen. I am 
almost inclined to doubt, if the much more brightly coloured birds described 
by Jerdon, and of which a specimen is sent by Mr. Mandelli, are really iden- 
tical, but a series is necessary for deciding this. In the bird sent to me the 
wing measures 2T, tail T5, tarsus 0'82 inch. ; the dimensions are rather less 
than those of the type specimen, so that, if the differences are sexual, the 
female would appear to be the larger bird. 
625. Ixttlus steiattjs, Blyth. 
Neither Mr. Blyth in his original description of the Tenaserim speci- 
men, nor Dr. Jerdon in the characters taken doubtless from his Darjiling or 
TChaiaf birds, mentions one of the most characteristic peculiarities of this 
form, — its ferruginous brown ear coverts and supercilia. In the type from 
Tenaserim, which is in the Indian Museum, I can detect these, although 
they are paler (perhaps from fading) than in a fresh specimen obtained by 
Mr. Mandelli, which otherwise agrees perfectly with Dr. Jerdon’s descrip- 
tion. Wing 2'35, tail 2T, tarsus 0'6, bill from forehead 0'35 inch.
