This fish appears to have been alive when taken, as the skull and 
brain had been punctured by the fisherman. The greater part 
of this fish was cooked ; it was very firm and fat, and the three 
persons who made a meal of it pronounced it capital. I tasted a 
portion of the flesh from a part where the fungus covered the skin, 
and could not detect anything different in the flavour from an 
ordinary fishmonger’s salmon. 
The fungus appears, in the first instance, to attack those parts of 
the fish that are not covered with scales, as the crown, nose, sides 
of the head, chin, throat, and the membranous parts of the fins. 
From those parts the fungus extends by vegetative growth (which 
seems very vigorous), to those portions of the surface of the body 
which are covered with scales. On the sides of the fish where 
small patches of the fungus were situated on the scales (and no 
rubbing had taken place) no sore could be detected, and the fungus 
was easily wiped off with the finger. 
I may also mention that all the fish which I received from the 
Eden river, both trout and salmon, were infested with tape- worms 
of a large size, the worms being about 2 yards in length and ^-ths 
of an inch in breadth. One of the salmon had from 60 to 80 yards of 
those worms in the pyloric portion of the gut. Another salmon had 
three varieties of worms in various parts of its alimentary canal. 
ls£. In the stomach were many round worms, about 4 inches in 
length, tapering to each end, and as thick as ordinary whip- cord in 
the thickest part of the body ; many of those worms were entangled 
among the gill rays, it being their habit to crawl there when the 
fish dies, and from their presence in this situation they are called 
gill worms by the fishermen. 2 d. A small spiral worm, which 
attaches itself, by burrowing in the outer walls of the intestine, in 
the fat and pyloric appendages. 3d. Tape-worms seated within the 
pylorus and intestine. 
On 30th May, I received from Sir Eobert Christison a large 
salmon from the Mth. This fish was believed to have been to the 
sea, after being attacked with fungus, and was captured on 
its return. The specimen was a female, and had the roe about 
one-fourth grown ; the viscera were very healthy, and no entozoa 
were found in it. The head of this female is peculiar in having a 
kip on the under jaw, and a cavity in the upper jaw to receive it,
