56 Messrs. Robinson and Kloss on Birds from the 
169. Chloropsis cyanopogon. 
Chloropsis cyanopogon (Temm.) ; Sharpe, Cat. Birds B. M. 
vi. p. 32; Robinson, p. 193. 
Rare in Trang. 
170. Irena cyanea. 
Irena cyanea Begbie; Sharpe, tom. cit. p. 179 ; Robinson, 
p. 193. 
Common in Pulau Langkawi and Pulau Terutau and in 
the Peninsula generally south of Trang. 
171. Irena puella, 
Irena puella (Lath.); Sharpe, tom, cit. p. 177. 
Exceedingly abundant in the open park at Chong, flying in 
small flocks of five and six. 
This “ species ” replaces I. cyanea in the northern parts of 
the Peninsula. The differences are very trivial, the present 
bird having much shorter under tail-coverts. 
172. Hemixus cinereus. 
Hemixus cinereus (Blyth); Sharpe, tom. cit. p. 52; Robin¬ 
son, p. 193. 
Only two specimens were obtained of this species, which 
is found only in the Malay Peninsula and Sumatra, not 
extending to Tenasserim. 
173. Hemixus malaccensis. 
Hemixus malaccensis (Blyth) ; Sharpe, tom. cit. p. 52; 
Robinson, p. 194. 
Also rare in Trang. 
The Bulbuls of this genus are forest and jungle birds, and 
are not found in orchards and cultivated land like the species 
of Pycnonotus and some others, notably Otocompsa emeria 
and Trachycomus ochrocephalus. 
174. IOLE OLIVACEA. 
Iole olivacea Blyth; Sharpe, tom. cit. p. 55 ; Robinson, 
p. 194. 
Three specimens of this species collected in Trang are 
perfectly typical and do not approach the greener Tenasserim 
bird I. viridescens Blyth, as might perhaps be expected.
