 the birds by their numbers as follows :

The measurements (taken from dried skins) show that the two 

 adult males are somewhat larger than the females, the greatest 

 difference being in the wing, tarsus, and culmen. No. 5 is con- 

 siderably larger than the others, in most of the measurements. 



Nos. 3 and 5 (adult males) have the back black, glossed 

 with green, as in e.xilis, without any traces of brown ; the black 

 feathers covering the back of the neck are much more conspic- 

 uous than in the females, and are glossed with green, the same 

 as the back. No. 5 is much richer in color on the under parts, 

 and has a considerable amount of white (which is wanting in 

 No. 3) on the abdomen, thighs and anal region. 



Nos. 2 and 4 (adult females) are similar in coloration to the 

 males, but the occipital crest is not so evident ; and the color of 

 the back shows traces of brown, No. 2 being a decided brownish 

 tinge, while No. 4 is glossy green, with traces of brown. The 

 tails of both are dark glossy green. The rufous of the sides of 

 the head, in No. 4, extends anteriorly over the eye, to the fore- 

 head, forming a narrow frontal margin of rufous ; in No. 2 it 

 just passes the eye, not reaching the forehead ; the white 

 'feathers on the thigh are absent in No. 4, otherwise they are 

 alike.
