Common as far up as the Gareloch, usually on 

 hard ground in 10-40 fathoms. Many females with 

 ova in March. It is aiDparently the commonest and 

 most generally distributed Galathea in the Firth of 

 Clyde. A Bopyrus is frequently found in the 

 branchial chamber, and Sacculina occurs rarely on 

 the abdomen. 



This species is very closely allied to G. nexa, and 

 we believe that subsequent examination may show 

 it to be only a well-marked variety, or possibly 

 founded on the females and young males of the latter,

This interesting species Avas originally described in 

 the British Stalk-eyed Crustacea from specimens 

 taken by M'Andrew in Loch Fyne. We dredged 

 it there at depths of 10 and 105 fathoms, on a 

 muddy bottom, and Mr. Brook obtained it off 

 Tarbert. It also occurred sparingly off Wemyss 

 Bay, 40 fathoms, and several miles off' Brodick Bay, 

 93 fathoms, in both instances on soft ground. 



The colour of liA'ing specimens is a beautiful flesh 

 tint deeper on the abdomen, with the limbs white.
