cheeks olive-brown, washed with tawny buflF, especially on the fore 

 part of the latter ; throat entirely white, the sides of" it brown like

 thighs ; lower breast and abdomen white ; under tail-coverts white ; 

 under wing-coverts white; axillaries olive-brown, edged with white ; 

 quills below dusky brown, ashy or huffy whitish along the inner 

 edge. Total length 47 inches, culmen 0-5, wing 2-45, tail l-fi,

I may at the same time take the opportunity of describing a 

 second new species from Perak : — 



DiGENEA MALAYANA, Sp. n. 



Adult male. Similar to D. moniliger in the rufous appearance of 

 the wing, and deep olive-brown on the back like that species. It 

 differs from it in having rufous cheeks and ear-coverts, and in the 

 forehead, lores, and eyebrow being deep orange-rufous, almost chest- 

 nut in tint. Total length 4-.o inches, culmen 0*5, wing 2-65, tail 1-85, 

 tarsus 0*75. 



Hab. Mountains of Larut, Perak. 



From Diqenea suhmoniliger this species differs not only in the 

 reddish colour of the wings, but in the rufous on the head and the 

 orange of the lores and eyebrow. 



The following is a revised " Key to the species " of Diqenea (cf. 

 Cat. B. iv. p. 458) :— ^ v-/ 



a. Olive-brown above ; breast and sides of body olive-brown. 

 a'. Base of forehead tawny buff or rufeseeut. 



a". Outer aspect of quills rufescent. 



a'". Ear-coverts ashy olive-brown ; eyebrow tawny buff ... moniliger. 

 b"'. Ear-coverts rufous brown ; eyebrow and lores orange- 

 rufous nialayana, 



b". Outer aspect of quills olive-brown, scarcely different from 

 (lie back ; lores and eyebrow tawny buff; ear-coverts 



brown, with a ruddy tinge submoniligcr, 



b'. Base of forehead and lores white albi/rons. 



b. Eufous-brown above and also on the breast and sides of body ; 



eyebrow and lores deep chestnut ; sides of face also chestnut, solitaria. 



The very peculiar coloration of these birds and their constant 

 black necklace on the throat makes me doubt whether they i^hould 

 be united to Digenea, in which the mode of colour is so different. 

 They might, ]ierhaps, be fairly separated as Jnthipes, in which case 

 they would have to be called A. moniliger, A. malayana, A. sub- 

 moniligei; A. albifrons, and A. solitaria.
