30 MK. C. LIODEN KLOSS ON 



patch on the crown (which gives its name to the species) is not 

 always isolated. The pale area on the hands and feet varies in 

 extent ; sometimes it covers the extremities from the wrists and 

 ankles and sometimes is confined to the fingers and toes. 



The two adult females are drab above, the rump and outer 

 .side of limbs somewhat warmer in tone, being slightly tinged 

 with ochraceous. The crown, cheeks, throat, and a diamond- or 

 shield-shaped area over the breast and abdomen extending to 

 the axilla? and almost to the genital region are bla,ckish. The 

 hands and feet, inner side of limbs, and the pelage bordering 

 the black areas ai-e somewhat lighter than the rest of the body. 



The young female is drab to buffy throughout except for a 

 slightly indicated dark cap on the top of the head. 



Gray was only able to state that the pale examples examined 

 by him were " probably female." I was told by Siamese villagers 

 who saw my specimens that females were always pale on the 

 back and limbs, while the abdominal surface is variable {cf. de 

 Pousargues, op. cit. p. 516). 



I am of opinion that this animal should be given only sub- 

 specific rank and treated as a geographical race of II. lar, which 

 occurs as far east as Luang Prabang (de Pousargues, op. cit. 

 p. 511) and in Central Siam, east of the Menam (Gyldenstolpe, 

 Arkiv for Zoologi, Band 8, no. 23, p. 6, 1914). 



Though I only obtained these animals at two collecting-stations, 

 we heard them calling every morning from the hills all along the 

 -coast from Ok Yam on the Franco-Siamese boundary to the 

 mouth of the Ban Yao River near Chantabun. Their cry did 

 not appear to differ in any way from that of H. lar or H. agilis.

A single adult female of this species was obtained at Klong 

 Menao. This sex does not appear to have been fully desciibed, 

 so that an account of the present specimen may not be out of 

 place. 



Colour. — Crown, nape, and entire upper surface, outer side of 

 forearms, hands, and feet mummy-brown to olive-brown, slightly 

 lighter and yellower across the shoulders and lighter on the 

 upper part of forearms and on the sides, the hairs annulated with 

 dull pale buff. Thighs and buttocks paler and greyer (near 

 drab-grey), devoid of annulations, the hips somewhat more bufi'y. 

 Face, temples, sides of head and neck, and buttocks buffy-silvery 

 or dirty brownish white, underside of body and inner side of 

 arms more silvery. Tail mummy-brown below, blackish brown
