INACHUS. 17 
A sraall species, from six to eight lines long, first found 
by J. Crancli in Falmouth .Bay, and named by Dr. Leach 
after that distinguished collector, who perished on the Congo 
expedition. Mr. Thompson, of Weymouth, dredged two 
specimens at Weymouth, August 18, 1852, in six fathoms, 
shingle and weedy bottom. One of these was a female, and 
had two single ova; they are of a deepish yellow colour. 
Mr. Eyton has got it off the Isle of Man. A specimen was 
taken at Penzance by Mr. Couch (Rev. A. Norman). 
Gen. 3. INACDUS, Fair. 
Carapace about as wide as long, with a very short beak. 
Eye-peduncles can be folded back and lodged in the orbital 
cavity. Jaw-feet with the third joint longer than wide; 
nearly triangular, the fourth joint attached to its anterior 
and outer angle. First pair of legs very small in the female ; 
in the male, rather thick, and sometimes three times the 
length of the body ; the following legs cylindrical, those of 
the second pair always longer than the front pair ; the four 
hind pairs end in a very long cylindrical joint, which is 
pointed and very slightly, if at all, bent ; the abdomen formed 
of six joints.
