is much that of the dead leaves amongst which they are 

 scratching in search for insects and their larvae. As soon 

 as such a bird finds itself observed, it will rest motion- 

 less on the same spot until it believes the danger to be over. 

 This species is known from Malacca, Sumatra and Borneo. 

 From this latter island it was unknown until a few years 

 ago, when it was found by Mr. Everett on M* Penrisen, 

 and by Mr. Hose on M* Dulit, Mt Kalulong and MtMulu.

Pomatorhinus horneensis Cat. Mus. Hein. I, p. 84 (1850); Salvad. Ucc. 

 Born. p. 210; Everett, L. B. Born. p. 104; Sharpe, Ibis 1889, p. 411. 



A great number of specimens from Mounts Kenepai and 

 Liang Koeboeng. Also from the Upper Mahakkam. — Iris 

 pale yellow, bill horny white, culmen black on the basal 

 three thirds, feet grayish blue, toes underneath ochre. 



This exclusively Borneau species seems to be spread over 

 the whole island, as it was already recorded from the 

 South-east, the North-west and the North.

Numerous specimens from the Mounts Kenepai and Liang 

 Koeboeng, and from the Sibau- and Siniai valleys, and

 specimen from the Siniai valley (at the eastern foot of the 

 Liang Koeboeng) has hardly any black stripes on breast 

 and belly, while a male from the same locality has the black 

 shaft-stripes very strongly developed. — Iris from terra- 

 cotta-yellow to yellowish white ; eyelid and skin on face 

 and throat sky-blue to purplish blue, and a stripe on 

 both sides of the throat cobalt-blue; bill black, lower man-
