 and having the same broad black band enclosing the ear-coverts and 

 joining a broad nuchal collar of black ; the lores and feathers below 

 the eye are also black, whereas in ff. solomonis they are green. 

 The entire mantle is blackish. " Bill black, white towards the base 

 of the lower mandible ; feet black ; iris black "' {E. L. Lai/ard). 

 Total length 8 inches, culmeu 1'6, wing 3'6, tail 2-45, tarsus 0-6.

 Todirhamphus collaris, Moore, P. Z. S. 1854, p. 269 (Penang). 



Adult nude. General colour above bright blue, the lower back, 

 rump, and upper tail-coverts deep cobalt ; wing-coverts brilliant 

 blue ; outer aspect of quills and tail deep rich ultramarine ; crown 

 of head bright blue like the mantle ; lores white, connected with a 

 narrow line of white above the eye ; below the eye a white spot ; 

 on the occiput a concealed patch of white ; ear-coverts bright blue 

 like the crown ; the nuchal collar, separating the occipital patch from 

 the white hind neck, also blue, like the ear-coverts, with which the 

 collar is continuous ; round the neck a broad white collar ; cheeks 

 and under surface of body white, with an orange-buff tinge on the 

 sides of the body and flanks. Total length 8-5 inches, culmen 1-8, 

 wing 3'9, tail 2-6, tarsus 0'6. 



Adult female. Similar to the male, but not quite so bright and a 

 little greener ; the ear-coverts as bright as the crown. Total length 

 S'o inches, culmeu 1-9, wing 4*15, tail 2*7, tarsus 0-65. 



The fulvescent tinge on the flanks in female birds is often almost 

 obsolete. 



A specimen from Penang has the entire sides of the body orange- 

 buff, aud it is probable that the young birds are even more tawny 

 on the flanks than the adults, as there are in this individual some 

 signs of dusky margins to the feathers of the white cervical collar.
