Adult female. Similar to the male. Total length 4 inches, 

 culmen 0*5, wing 2*05, tail 1'35, tarsus 0*6. 



[Met with only in one locality on Kina Balu, at about 

 5000 feet. I found a nest of this species, which was built of 

 fine roots on the underside of a moss-covered bough, in the 

 dark damp forests on the slopes of the mountain. The old 

 birds were feeding their young on grubs.]

The affinity of this species with Dicaum sulaense instead 

 of with D. celebicum is most interesting. The steel-blue 

 colour of the back separates the Kina Balu bird from both, 

 but it has olive-yellow flanks like D sulaense. Of the latter 

 species the female is at present undescribed, but between the 

 hens of D. celebicum and D. monticola there is a great 

 difference, the female of the Celebean bird being dull purplish, 

 while the female of D. monticola is olive-yellowish on the 

 back, clearer olive-yellow on the rump and upper tail-coverts ; 

 the head dusky steel-green washed with olive ; wing-coverts 

 blackish, with a steel-green gloss, and edged with olive-yellow ; 

 quills blackish, with narrow olive edges ; tail-feathers blue- 

 black ; sides of face dull ashy shaded with olive, as also the 

 cheeks, with a grey shade over the sides of the fore neck and 

 chest; throat white, gradually turning to pale ochreous 

 yellow on the breast and abdomen and under tail-coverts ; 

 sides of body olive; axillaries, under wing-coverts, and quill- 

 lining white, with a yellow tinge. Total length 3'2 inches, 

 culmen 0*4, wing TSS, tail 0*95, tarsus 0'5. 



The young bird resembles the adult female, but has the 

 base of the bill yellowish white and the colours duller ; the 

 head olive like the back ; the throat pale ashy grey, this 

 colour extending over the breast.
