INACHUS. 17 



A^ small species, from six to eight lines long, first found 

 by J. Cranch 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. INACHUS, Fabr. 



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.
