“Tris hazel, bill black, yellowish at base and on parts of 
lower mandible, feet yellowish brown.” 
Living in undergrowth and low bushes in dense jungle, 
generally moving about in pairs, searching the branches for 
Insects, etc. Very active and extraordinarily fearless, 
uninjured specimens being consequently somewhat difficult, to 
procure. 
Salvadori separated this form from the Javan P. cucullatus 
on the assumption that the adult bird possessed a dark green 
pileum, which the present series shows not to be the fact. 
The form, however, agrees with P. c. cinericollis, Sharpe, from 
Kinabalu, in the possession of a dark grey collar on the hind 
neck, but differs slightly in the deeper, more chestnut tint of 
the pileum, in the darker green of the upper parts and in the 
richer vellow of the flanks and abdomen. There is no trace 
of white edgings to the outer tail feathers, which are ten and 
not twelve in number as surmised by Salvadori (loc. cit.) 
Both Sharpe (Hand-list Birds, iv, p. 237 (1903), and 
Hartert (Nov. Zool. iv, p. 518 (1897), include the Malay 
Peninsula within the range of the Indian species, Ph. coronatus 
(Jerd. and Blyth), but we are urtaware of any authentic speci- 
mens of this species from south of Muleyit in Tenasserim. Of 
the considerable series of P. cineveicollisin the F.M.S. Museums, 
three from the Semangko Pass, Selangor-Pahang boundary ; 
Telom, Perak-Pahang boundary and Gunong Tahan, have 
traces of a white edging to the inner webs of the outer tail 
feathers, in all cases not nearly reaching to the shaft. Others 
from the same localities have the tail entirely without white. 
According to Hartert’s Key to the species (loc. cit.), the 
three above mentioned specimens would belong to his Ph. c. 
philippinus, but a more reasonable explanation is that the 
white on the tail is an atavistic character occasionally 
appearing amongst the forms normally without it.
