legs of the male thick, not reaching beyond the penultimate 

 joint of the second pair of legs. 



This species seems to be pretty generally distributed on 

 the coasts of England and Ireland. Mr. Eyton finds it off 

 the Isle of Man, and the Eev. A. Norman describes it as 

 not uncommon among the Channel Islands. Mr. Thomp- 

 son, who finds it at Weymouth, describes the ova as large 

 and of an orange-brown colour; the colour of the animal is 

 dingy purple, brighter on the fore part of the carapace. 



Inachus leptochirus, Leach. Slender -armed Sjnder 

 Crab. — Stomachal region with three spines placed triangu- 

 larly. Fore legs of the male slender and reaching beyond 

 the penultimate joint of second pair of legs. Sternum of 

 the male furnished with a small oval polished tubercle. 



First found by Mr. Cranch on the coast of Devon or 

 Cornwall; it is found in Ireland. The Eev. G. Gordon 

 (' Zoologist/ 3681) says that five specimens were taken 

 from the stomach of a cod in the Moray Firth in 1849, and 

 some were subsequently found in the Forth. The Eev. 

 Alfred "Norman found it not uncommon in forty fathoms, 

 seven miles off Falmouth ; he has taken also a fine specimen 

 of the female in the Firth of Clyde.
