Described and figured from the holotype, a female, 157 mm. long from 
the tip of snout to the hypural joint, which was trawled on the west coast 
of the North Island of New Zealand in June, 1921. Its greatest height 
is 88 mm., the length of the head is 43 mm., diameter of the eye 17 mm., 
and the depth of the caudal peduncle 24 mm 
Variation.—Three specimens were trawled about the same time, two of 
which were females, with the third a male, the latter being much narrower 
in body than the females ; apart from this they appeared identical in every 
other way. 
Affinities —This species is very similar to Chromis hypsilepis, recorded 
from Lord Howe Island, and the coast of Australia near Sydney, and 
described and figured by Mr. A. R. McCulloch in Zool. Res. “ Endeavour,” 
pt. i, p. 73, pl. xiv, 1911. In submitting a specimen of our species to him 
for comparison with C. hypsilepis, he writes as follows: “I have carefully 
compared your specimen with several of C. hypsilepis, and am satisfied it 
represents a distinct species. Apart from the colour-marking, the differ- 
ences between the two are comparative, and cannot be expressed in definite 
terms." 
Locality.—Trawled off Reef Point, a little to the south of Ahipara Bay, 
North Auckland district.*

During the months of June and July a number of specimens of the 
mirror-dory were trawled by the s.s. “James Cosgrove” between White 
Island, in the Bay of Plenty, and the entrance to the Hauraki Gulf, Auck- 
land, this being, I believe, the first time the species has been recognized 
rom our waters. The most noticeable difference between this fish and the 
common john-dory (Zeus faber) lies in the remarkable mirror-like appear 
ance of the scaleless body of the former, while it has three only instea of 
four anal spines. That it has not often been seen in the Auckland markets 
is doubtless due to the fact that it is a deep-sea species, and our trawling 
operations seldom extend to the deep waters it inhabits. From recent 
observations I feel confident it is fairly plentiful with us, and should become 
an important addition to our list of prized table fish. 
Locality.—From Hauraki Gulf to White Island, in the Bay of Plenty. 
McCulloch records it from off Cape Everard, Victoria, in 70 fathoms, and 
from twenty miles north-east of Babel Island, Bass Strait, in 68 fathoms, 
and Disaster Bay, New South Wales, in 45 fathoms.

* Since the above description and figure were prepared I have received five other 
fine specimens, caught at the Mokohinau Vent br Me Shirley, a local fisherman, 
who reports that it is not an uncommon species in that neighbourhood, but difficult to 
catch with hook and line. 3
