96 THE EDIBLE FISHES OF NEW SOUTH WALES. 
Southern Tunny (Thunnus [Germo] maczoy). 
During June of last year (1907) large shoals of this 
mighty mackerel were discovered to be present in our coastal 
waters in the immediate vicinity of Port Jackson and Port 
Hacking; and some of the fishes made their way into the 
mouth of Port Jackson. The individuals in these shoals 
averaged from 5 to 7 feet in length, and were of a great 
weight. The first example taken was harpooned off the mouth 
of Port Hacking by a party out in pursuit of porpoises 
(Dolphins). This was examined by me and identified with 
Castelnau’s Thynnus maccoyt. I found it to measure 4 feet 
ro} inches to the fork of the tail, and it weighed 139 pounds. 
During the next few days succeeding, a few of those which 
entered Port Jackson Heads were captured by a fisherman 
in the vicinity, using a “ Kingfish net” ; and these were said 
to be about 7 feet long. On both occasions, the water off 
shore was stated to be literally alive with these Tunnies. 
Again, during September, the men (Goldsmith Brothers) 
who harpooned the first one, happened on a large shoal of 
the young of this species, and about twenty were captured. 
One of these preserved by me weighed 124 pounds. 
Though these are the only definite records of the occur- 
rence of this mighty and useful food-fish in New South Wales 
waters, it 1s highly probable that they are, and have been 
often present, but unrecognised, and it seems to me very 
likely that the young at least have been confused at times 
with the Bonito. 
A statement of the colors as noted by me at the time 
that I identified the first specimen, mentioned above, will not 
be out of place:—Upper parts, deep bluish-black, becoming 
steel-blue towards the sides, and working into a deep-brownish 
tinge on the top and upper part of the sides of the head; 
sides ashen-grey, dusted over with darker. (No very distinct 
line of demarcation between color of back and sides.) Lower 
surface, coral-white. Iris, yellowish-orange, sparsely dusted 
ever with darker. Projection on each side of tail, orange- 
yellow with a bluish-green margin. A somewhat leaden or
