Station; it shows considerable vertical range, having been 
trawled between 9 and 183 fathoms. 
This fish formed the principal subject of the paper by Dr. Gill, 
above listed, but having but a single specimen, the author was 
unable to sacrifice it to ascertain its anatomical structure. He 
writes :—‘‘ We may hope that perhaps Professor Parker, to whom 
we are indebted for excellent memoirs on the anatomy of several 
fishes of his adopted home, may give himself, or depute a student 
to give us, some details as to the anatomy of a fish which does 
not appear to be excessively rare in New Zealand.’’ I was 
particularly unfortunate in my selection of a specimen for 
anatomical examination, for choosing one which was unsatisfac- 
tory as regards its exterior I found that the skull was broken 
to pieces and so crushed as to render it impossible to ascertain 
the original condition of the bones. Moreover the specimen was 
preserved in formaline, a medium which so hardens the tissues 
as to make dissection from bones which appear to be semi- 
cartilaginous, a rather difficult matter under the best conditions. 
I possess only one example preserved in spirits, and this I have 
sent to Dr. Gill with the request that he will examine it, so that 
we may have the benefit of his wide experience in all matters 
connected with the anatomy of fishes. 
The following are the few notes revealed by an examination 
of the imperfect specimen above referred to :— 
Beevile; 1) A selene A AZ Vo deco 20+ ©. 10-8: 
The vertebrze number 33, there are four gills, no slit behind 
the fourth, gill-rakers ten, eight being on the lower limb of the 
first arch, they are very small and widely spaced, the upper 
pharangeal teeth are two rounded masses, the lower ones are 
smaller and flat. 
Though known to attain a length of 407 mm. (= 16 inches). 
all the examples taken in the trawl are much smaller, and 
specimens 188 mm. in length have the ova fully developed. 
Family TRIGLIDA. 
The three genera of Gurnards known in New Zealand waters 
may be thus identified :— 
a. Seales very small. 
b. Spiny scutes at the bases of both 
dorsal fins. . a a Chelidonichth YS. 
bb. Flat scutes at base of first dorsal 
only ee Pterygotrigla. 
aa. Scales large, lateral line with 75 or 
fewer scales... oe oy Lepidotrigla.
