fish. He thinks that the fish described by Dr. Shaw in his 
General Zoology, and placed by him in the thoracic order under 
the name of Vandellius lusitanicus, isthe same fish. It was the 
inaccurate position of this fish by Shaw that prevented him from 
recognizing the identity sooner. Risso, in his Ichihyologie de 
Nice, has described three species belonging to this genus, under 
the generic title Lepidopus, but has placed them inaccurately in 
the thoracic order. 
Col. Montagu gives a figure’ and an accurate description of 
the Leplocephalus Morrisui, first described by Pennant, though 
afterwards its existence was called in question. The author 
obtained two specimens of this rare fish, from his friend Mr. 
Anstice, of Bridgewater, near which place they had been taken. 
From these specimens, one of which was quite perfect, he has 
been enabled to draw up a much more accurate description than 
had been previously given by Pennant, whose specimen had been 
incomplete. 
In the first volume of the Wernerian Memoirs, Mr. Neill relates 
his observations on the Callionymus /yra and dracunculus, from 
which he concluded that the ditference between these two fishes 
is merely sexual, the former being the male, and the latter the 
female. Col, Montagu is induced to throw some doubts upon 
the accuracy of this conclusion, from the circumstance of the 
callionymus dracunculus being very common upon the coast of 
Devonshire. The fishermen of Torcross alone catch above 1000 
of them annually ; but the callionymus lyra is very rarely met 
with in that quarter. Col. Montagu only procured one specimen, 
which a fisherman sent him as a rare fish, with which no body 
in his neighbourhood was acquainted. He requests the secre- 
tary of the Wernerian Society to go on with his dissections at 
different seasons of the year till the sex of the callionymus 
dracunculus be ascertained ; for at the time that he published 
his paper in the first volume of the Wernerian Memoirs, on the 
fishes in the Frith of Forth, he had not been able to find traces 
either of roe or melt in that fish. 
The blennius ocellaris is well known as a Mediterranean fish, 
but was not supposed to occur on the coast of Great Britain ; 
but three of them were taken by the dredge in 18]4 on the 
oyster bed at Torcross on the south coast of Devon. The author 
had an opportunity of examining them all, and one of them indeed 
i= a living state, He gives a figure and description of this fish, 
and points out the mistakes respecting it ito which preceding 
ichthyologists had fallen. 
The author next gives a correct description of the blennius 
gattorugine, and gives some valuable characters by which certain 
species of blennius may be distinguished from the rest, 
The remainder of this valuable paper is taken up with remarks 
on the gadus argenteolus, a small species of gadus which has been 
hitherto confounded with the gadus mustela: with an account of
