to about 8 fathoms, probably because of the exposed and shifting 

 character of the sand, but locally in 12 to 30 fathoms it is fairly 

 numerous. It is seldom found in shallow water at Polperro, but 

 is common on suitable ground at Mevagissey and Gorran Bay. 

 In Gerrans Bay it is unusually plentiful in 8 to 14 fathoms in 

 sandy lanes and patches, and from Falmouth Bay to the Lizard 

 is well represented from low-water mark downwards. It is 

 irregularly distributed but by no means uncommon in Mount's 

 Bay, and has been captured both at Porth Curnow and at Sennen 

 Cove. At St. Ives, Vallentin finds it fairly common in 8 to 10 

 fathoms, though only taken by trawlers at night. It occurs in 

 5 to 20 fathoms west of Chapel Porth, is frequently captured at 

 Padstow and brought in by trawlers there. It has also been 

 forwarded from Port Isaac and from Trebarwith. At Scilly it 

 has been captured in St. Mary's Sound, at the Cove, St. Agnes, 

 and in 25 fathoms south of Trinity Kock. Females have been 

 taken in berry during the months of May and June. 



The Circular Crab, Atelecyclus septemdentatus (Mont.), is 

 evidently a favourite food of Cods and Kays ; and it was chiefly 

 in the stomachs of these fishes that the older naturalists like 

 Couch and Cocks obtained their specimens. It is, however, 

 locally common and at times abundant in 15 to about 45 fathoms 

 on muddy gravel and occasionally on sandy gravel all along the 

 south coast from the Mewstone grounds to the Wolf. It occurs 

 in quantity about a mile east of the Eddy stone, and also about 

 three miles to the west (M. B. A.), has been dredged in 13 fathoms 

 about two miles south-east of Longstone Kock, Whitsand Bay, 

 is fairly common eight miles south of Polperro, in 15 fathoms 

 off Fowey and about three miles east of Gwineas Kock in Gorran 

 Bay. It is of frequent occurrence outside Falmouth Bay, and 

 there is a thickly populated patch in 30 fathoms about two and 

 a half miles E. \ N. of Porthallow, and another in about 

 45 fathoms nine miles east of Coverack. On the north coast it 

 is fairly common in 20 fathoms eight miles north-east of 

 St. Agnes Head, and occurs in trawl-refuse at Padstow. At 

 Scilly it is abundant in 40 fathoms three miles north-east 

 of St. Martin's Daymark. Females in berry are commonest 

 in May.
