BIRDS OF NEW ZEALAND NOT FIGURED BY BULLER. 
of white feathers recalling colensoi. In the Enderby Island form, which should 
be colensoi, we have sometimes a specimen with the dark neck-band of the adult 
quite entire, recalling campbelli. If picked birds are placed in a row, we have 
connecting links from the true campbelli through colensoi to ranfurlyi. 
From Enderby Island also we have a skin approaching the adult stage 
(No. 16), with the dark band entire and very wide, and must be campbelli. 
Hypoleucus campbelli colensoi (pi. 98). AUCKLAND ISLAND SHAG. 
This is about the same as campbelli and represents it in the Auckland Islands. 
Adult. Crown of the head, nape and neck, glossy purplish, like the back, 
rump and thighs ; fore-head, crest and sides of the face greenish ; tail, upper and 
under tail-coverts, and a line extending from either side to the thighs, black; 
primaries black edged with green, secondaries green ; some of the wing-coverts 
white forming a distinct wing-bar; inter-ramal space, chin and upper throat 
white ; this white surrounded by a purplish band, more or less divided ; 
remainder of the under-surface, including the sides of the body, white ; eyes 
dark brown ; bill brownish-black, orange at the gape ; ring round the eye 
purple, bare skin on the face dark brown, gular pouch arterial red, feet flesh 
colour, w r ebs brownish. Total length 650 mm. : culmen 54, wing 268, tail 118, 
tarsus 62. 
This form resembles onslowi in the colour of the upper-surface; it has a 
wing-bar but no dorsal patch ; it has no caruncles and is about the same size as 
onslowi. The absence of caruncles and the dark glossy purplish band on the neck 
will ahvays distinguish it. 
In the immature stage the band below' the white chin is not divided. 
The typical colensoi lias the top of the head metallic-greenish, blending into 
purple on the nape and back of the neck and extending on to the lower neck. 
Now r here again another closely allied sub-species has been collected on Enderby 
Island which has the top of the head metallic-green as in colensoi, blending into 
a purple tinged with green on the nape, back of the neck and under neck. 
Collected on Enderby Island on January 3rd, 1901. 
This is very puzzling ; w r e either have two species, or colensoi is very change¬ 
able in different skins, and must be considered a sub-species of campbelli. 
Adult. Differs from campbelli in being bronzy greenish-brown on the 
upper-surface, instead of purplish steel-blue ; the band on the neck, surrounding 
the white chin patch, is narrower and sometimes divided by a white line more or 
less interspersed with dark feathers. It has a wing-bar and sometimes (not 
always) a dorsal patch of white. Eyes dark brown, ring round it purple ; face
