64 Messrs. Robinsou 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. 



"4-210. 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 (Miill.); Seebohin, 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 Pulau Pandan, 

 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 Henicurvs schistaceus and Hydrocichla rvfi- 

 capilla, the only other Fork-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. 



Ei'ithacus cyaneus Seebohm, Cat. Birds B. M. v. p. 303 ; 

 Robinson, p. 207. 



Very numerous in all the inland localities in Trang.
