lateral line, but failing to meet underneath. The 
presence of a swim-bladder sufficiently distin- 
guishes this species from the Common Mackerel, 
which has none. 
BOAR-FISH ( Capros aper ). — On June 3rd, 1913, an example 
was sent me by a Lowestoft fish merchant ; it 
had been taken in a shrimp-net on Corton Patch. 
One that I did not see was captured near 
Yarmouth on the same date. 
Gattorugine ( Blennius gattorugine). — A very beautiful 
specimen of this rare East Coast visitor (the 
second for Norfolk) was brought me on April 
7th by a local shrimper. Length, 5 in. 
CUCKOO Wrass (Labrus mixtus). — The occurrence of this 
species is so rare off the East Coast of England 
that an example sent me by Mr. F- C. Cook 
from Lowestoft is worth recording. Cordeaux’s 
one “record” (“Handbook of Yorkshire 
Vertebrata,” p. 117) is barely authentic; and 
Howse (“ Fishes of Northumberland and 
Durham ”), referring to it as the Cook, or 
Variegated Wrass, mentions it as “ resting on 
the authority of the fishermen, and a fresh- 
caught specimen is much desired for examination 
and verification.” The Wrass sent me was 
captured in the trawl in the vicinity of the 
“Galloper” (light-vessel) in December, 1910. 
Length, 8| in. Had not been recorded before 
for Essex. Vide “Zoologist,” January, 1911. 
I am inclined to believe that what Dr. Lowe 
(“Victoria History of Norfolk ”) records as the 
Green Wrass ( Labrus mixtus ) was only the green 
variety of the Ballan Wrass (L. maculatus). 
H^EMULON. — Mr. Cook found the head and backbone of an 
American fish, washed up on Lowestoft beach 
early in December, 1910. I submitted the 
“remains” to Dr. Boulenger, who described it as
