HYPOLEUCUS CAMPBELL!. 
CAMPBELL ISLAND SHAG. 
(Plates 98, 99 & 100.) 
The typical form has the head and neck all round purplish-blue ; forehead, 
crest and sides of the face greenish. Wing 260 to 268 mm. Campbell Island. 
In the Tring Museum are five adults, two nearly so, and eight immature, 
all from Campbell Island. 
In four of the adults the blackish-purple neck-band is quite wide, 
true campbelli; in one the neck-band is almost divided by white feathers, and 
recalls colensoi; in two nearly adult the neck-band is narrower than it is in the 
quite adults or in some of the immature. In three immature the dark neck-band 
is ver\' narrow. 
The immature differs from the adult in having the upper-parts brownish. 
The band on the lower neck, surrounding the white chin patch, is brownish. 
E}^e brown, bare skin black, bill and pouch flesh colour ; legs brownish flesh. 
Apparently this form never has a dorsal patch, even indicated by one white 
feather at any stage of its existence. The wing-bar is not obtained till the adult 
plumage is assumed. 
Now a form of campbelli has been collected on Enderby Island (one adult 
and one immature on January 3rd, 1901), wing 270, and one adult on Auckland 
Island on January 7th of the same year, wing 267. These two adults have the 
white chin patch entirely surrounded by a dark band which is entire and not 
divided by a white line of feathers, or even by a few' wiiite feathers. 
These tv r o skins differ from campbelli in having the dark throat-band much 
narrow r er both in the adult and immature stage. 
They cannot be colensoi as the throat-band is not divided in adult skins, and 
although the skin from Enderby Island is like the one Auckland Island skin, 
and colensoi occurs in Auckland and Enderby Islands, I cannot at present 
consider them colensoi. 
If they turn out to be colensoi then this form, in some skins, differs from 
campbelli only in having the dark throat-band narrow r er, and in having the 
neck bronzy green (not purple) ; that is uniform with the fore-head and sides of 
the face. It seems that in some campbelli from Campbell Island (the type 
locality), the dark neck-band of the adult is sometimes almost divided by a line
