64 Messrs. Robinson and Kloss on Birds from the 
wing-coverts and are therefore referable to this species; the 
character, however, is so variable that we rather doubt if the 
form can be maintained even as a subspecies. It is significant 
that in the southern part of its range the species is one of 
the most extreme rarity, and that no recent collector has 
met with it, though it has been specially searched for during 
the last seven years. The British Museum possesses no 
exactly localized or authenticated specimens from any penin¬ 
sular locality other than “ Malacca,” which is vague and 
unsatisfactory. 
210. Turdus obscurus. 
Merula obscura (Gm.); Seebohm, Cat. Birds Brit. Mus. 
v. p. 273. 
Quite common in Trang, more so than further south. 
211. Petrophila solitaria. 
Monticola solitaria (Mull.); Seebohm, tom. cit. p. 319. 
Petrophila solitaria Robinson, p. 207. 
A single specimen was shot at Kantan, Trang, near the 
coast of Trang, in December. 
We have examples of this species also from PulauPandan, 
between Langkawi and Terutau. It has not been recorded 
from anywhere south of the Larut Range in Perak. 
212. Hydrocichla frontalis. 
Hydrocichla frontalis (Blyth); Sharpe, Cat. Birds Brit. 
Mus. vii. p. 321 (1885). 
Ko-khau, Trang, North Malay Peninsula, January 10th, 
1910. 
Rarer than Henicurus schistaceus and Hydrocichla rufi- 
capilla , the only other Pork-tails whose occurrence in the 
Peninsula rests on well-authenticated specimens, the records 
of Henicurus leschenaulti and H sinensis being open to very 
considerable suspicion. 
213. Larvivora cyanea. 
Erithacus cyaneus Seebohm, Cat. Birds B. M. v. p. 303 ; 
Robinson, p. 207. 
Very numerous in all the inland localities in Trang.
