CAMPBELL ISLAND SHAG. 
In campbelli, in breeding-plumage, there are some white filo-plumes on 
the head and neck and over the eye, as in chalconotus in breeding-plumage. This 
probably applies to all the blue-eyed Shags. 
Adult differs from campbelli and colensoi in having the white of the under¬ 
neck, joining the chin and the under-surface, quite wide and entirely white, 
with no dark feathers showing. The upper-surface is more like that of campbelli , 
that is, purplish blue-black; wing-bar more or less pronounced; the white 
dorsal patch is only indicated by some white feathers. Eyes brown, ring round 
eye purple; lores scarlet or crimson with minute black plumes ; gular pouch 
scarlet, merging into orange near the bill; legs and feet light flesh colour. Wing 
284 mm. to 300, bill 57 to 60. Bounty Island only. 
In the immature this form resembles the immature of colensoi in that they 
have a white chin patch entirely surrounded by a dark neck-band. In the 
next stage the dark neck-band is divided by a line of white with brown feathers 
intermixed ; this band in the next stage is white and wide, with only a few dark 
feathers showing on the lower neck ; so far the birds have their upper surface 
brown. 
When the dark feathers of maturity appear, the white band connecting the 
chin with the under-surface is quite pronounced, wide and almost free from dark 
feathers. In the next or adult state the dark band has fallen back and is not 
noticeable, the white of the under-surface runs up the underside of the neck 
and joints the white chin. 
The young in the first plumage has the eye pale brown, the skin around and 
in front is brown ; gular pouch grey ; bill brownish, feet browny flesh colour. 
In the immature there is no wing-bar ; in the adult this wing-bar is more 
or less well defined, and the dorsal patch is absent or only indicated. 
In the adult state campbelli has the dark neck-band entire ; in ranfurlyi 
the dark neck-band is quite divided by the white of the under-neck ; in colensoi 
the dark neck-band is sometimes divided by a thin stripe in which there are 
some dark feathers or it may only be divided half-way across. So that colensoi 
seems to connect campbelli and ranfurlyi . 
In the adult state campbelli seems never to have a white dorsal patch ; 
ranfurlyi seldom and colensoi frequently. So that ranfurlyi seems to connect 
campbelli with colensoi. 
In the adult all forms have crests, which are probably shed in the non¬ 
breeding season. 
Thus it seems that we have the species campbelli from Campbell Island, 
which is represented by colensoi on Auckland and Enderby Islands, and by 
ranfurlyi on Bounty Island.
