this genus, which I could refer to no other species but this, 
was taken some time since near Falmouth ; but I have never 
met with a specimen. 
Besides these, I have met with a species which I have 
never seen described, unless it be the Esox Brasiliensis 
Linn. Syst. Nat. It was taken by me in the harbour at 
Polperro, in July 1818, as it was swimming with agility near 
the surface of the water. It was about an inch in length, 
the head somewhat flattened at the top, the upper jaw short 
and pointed, the inferior much protruded, being at least as 
long as from the extremity of the upper jaw to the back 
part of the gill-covers. The mouth opened obliquely down- 
ward; but that part of the under Jaw which protruded be- 
yond the extremity of the upper, passed straight forward in 
a right line with the top of the head. The body was com- 
pressed, lengthened, and resembled that of the Garpike, 
E. Belone : it had one dorsal and one anal fin placed far 
behind and opposite to each other; the tail was straight. 
The colour of the back was a blueish-green, with a few 
spots; the belly silvery. —

Grey Mullet. M. Cephalus.—This fish is known to exercise a 
considerable degree of cunning when it finds itself in situa- 
tions of danger; and it is particularly difficult to take it 
with a net. 
CLUPEA. 
Herring. C. Harengus.—Although the North seems to be the 
region of Herrings, those which are found on the Cornish 
coasts do not come from that direction ; nor do they at any 
time go to a great distance, as they are met with throughout 
the year, except perhaps for a short time in spring. The
