Salmon and trout were everywhere plentiful. Attached by a 
long, slender, central appendage (like that 
of a Clialimus) to the pectoral region of a 
Motella glauca, that swam amongst the salpac, 
was a remarkable crustacean parasite (fig. 7). 
A malformed young TurhoV^ was also caught 
as it disported itself amongst the salpac, having 
both sides of its body coloured, and with an 
eye on each; opercular bones on both sides 
armed with prickles. The dorsal fin com- 
mences rather behind the posterior border 
of the orbit, leaving a distinct crown of the 
head in front. The ventral line was flattened, 
had a prominent spinous process at the pos- 
terior termination of the lower jaw, in a line 
with the posterior part of the orbit, and a 
deep notch behind the rudimentary ventral 
fins. The directions of the axes of the eyes 
were different. The anal fin commenced 
behind the ventral notch. There w^as little 
abnormality in either pectoral or caudal fin, 
save that the latter was directed somewhat downwards (ventrally).
