This family is by Dr. M. Edwards placed among the Ocy- 
podes, but is here coupled with Gonoplax, from the great 
similarity of form and habit of the following Species. 
In the history of Crustaceans by Dr. M. Edwards, no notice 
is given of any species of this genus as found in the European 
seas; and therefore I feel some hesitation in assigning to it a 
species frequently found in the stomachs of fishes taken in 
depths varying from 5 to more than 20 fathoms : but of which 
no figure is found in the works of Pennant or Leach. 
The form of the carapace is represented by Dr.M.Edwards, 
Pi. 18, fig. 10, and consequently much resembling that of 
Gonoplax ; but that of the present species differs from the 
figure by that gentleman iu possessing a second well marked 
fiook on the lateral margin, a little behind the anterior angle, 
and at the place where in the Gonoplax Bispinosa there is a 
Protuberance much less marked, but giving origin to the tri- 
rial name. Both claws are of equal size, and less than the 
transverse breadth of the carapace. The eye stalks are con- 
pealed, in the manner of the gonoplax ; but as the carapace 
•s more advanced at the separation of the occular cavities, 
"'lien withdrawn their extremities point a little backward. I 
find but little difference in the form of the male and female, 
a nd none in the proportions of the claws, though such is the 
c ase for the most part in Crustaceans. I have provisionally 
designated it;

A species of the Genus Grapsus is in the Athenaeum at 
Plymouth, under the name of G. Pelagicus, by Mr. Prideaux 
a nd known to Dr. Leacb, but not in any published work. It 
ls understood that the collection in the Museum of that Insti- 
tution is confined to specimens taken on the borders ot Devon
