of the same author. The Rosy Flounder (Pleuronectes 
loseus) of Dr. Shaw, is certainly only an accidental va- 
riety in colour of the common Flounder, examples of 
which the river Thames affords in amazing number 
during spring, and summer f. The Pyramidal Limp~ 
sucker (Cyclopterus pyrainidalis) of the same writer, is 
only a distorted subject of the common LAimp-sucker'j' j 
and his Sparus Formosus, a fish, not of the Sparus, but 
Labrus genus, being no other than the striped Wrasse of 
1 ennant, and Lcdjrus xariegatus of Gmchn and other 
writers -j-. 
The oblong Sun-fish of the Ixveriau Museum was not 
an authentic specimen, but an ill-preserved skin of the 
round or common Sun -fish, and which has misled some 
authors so far as to consider the oblong Sun-fish a mere 
variety of the other. 
We could have wished also, that Dr. Turton, who has 
favoured the English reader with a valuable and useful 
translation of the Gmelinian System, had occasionally 
consulted the various publications, from whence his addi- 
tions to that work were selected, with greater caution ; 
for by inserting those, the species have, in some instances, 
been improperly multiplied, Gmeliu having before de- 
scribed the same fishes under other names. A strikine: 
example of this occurs in the genus Gadus, to which Dr. 
Turton adds as a new species the Scotch Torsk of Pennant, 
under the trivial appellation of Scoticus, not being aware 
that the same species is immediately before described by 
i-ff The specimens described by Dr. Shaw, formerly preserved in the 
Leverian Museum, are at present in the collection of the author.
