FROM THE EDDYSTONE GROUNDS TO START POINT. 487 



Evpagurus Bernhardus. Chart XII. Tliis hermit crab is present on 

 grounds of all kinds, though it is most abundant on the sand and on 

 the gravel and sand grounds where the fauna is generally rich. Its 

 absence from Ground XIII., the gravel and mud one mile south-east of 

 the Eddystone, is somewhat unexpected, but it must be noted that only 

 one haul was made here (103). It is noteworthy that on the fine sand 

 grounds (I., II., III., IV., V., and VII.) the anemone Sagartia parasitica 

 was often associated with the hermit, whilst on all the other "rounds 

 the anemone was al>sent (c/. p. 459). Eupagums Bernhardus was found 

 occupying the shell of Bnccinvvi vndatum on all grounds excepting on 

 the Bolt Head Shell Gravel (Ground XVII.), where specimens were taken 

 (in hauls 106 and 107) in Fusus islandicus shells. The Buccinicm shells 

 often had Hydradinia cchinata upon them. 



Distribution. Geographical. East Finmark, Norway, Sweden, Kattegat, Baltic, 

 British Coasts, Mediterranean (apparently not frequent). 



Depth. Shore to 200 fathoms (Pocock, No. 96). 



Bottom-deposit Metzger (No. 78) records E. Bernhardus in the North Sea on sand, 

 on gravel, on shell, and on mud, generally however, on fine ground. Meincrt (No. 75) 

 in the Kattegat on all kinds of ground, on clean sand, on mixed deposits, and on pure 

 mud. 



The distribution of this s^jecies is evidently little influenced by the nature of tlie bottom- 

 deposit. 



Uvpagurus Prideauxii (Chart XII.) differs somewhat in distribution on 

 the grounds investigated from U. Bernhardus, in that it is never found 

 on the fine clean sand of the outer and inner trawling grounds (I. and 

 II.). In other respects its distribution is practically the same as that 

 of U. Bernhardus. It is invariably associated with the anemone 

 Adamsia palliata. 



Distribution. Geographical. Mediterranean, Portugal, Bay of Biscay, English 

 Channel, Irish Sea, West of Scotland, Shetlands, Norway to Arctic Circle (Marion, No. 

 74; Gourret, No. 31 ; Bonnier, No. 10; Walker, Nos. Ill and 112; Hoyle, No. 52; 

 Norman, No. 93). It is not recorded by Metzger in the North Sea, nor by Meinert in the 

 Kattegat. 



Depth. From 10 or 20 fathoms to 140 fethoms (Gourret, Milne-Edwards and Bouvier, 

 No. 80). 



Bottom-deposit. Milne-Edwards and Bouvier (No. 80) record E. Prideauxii five times 

 from fine sand, or nmddy sand, and twice from sand, gravel, and broken shell, at depths 

 from 30 to 140 fathoms in the Bay of Biscay. Marion (No. 74) records it in the Mediter- 

 ranean on coralline gravel, on muddy sand, and nnuldy gravels. Walker (No. Ill) in the 

 Irish Sea on nullipore ground and on muddy gravel (20 fathoms). 



Eupagurus cuancnsis (Table VI.) is never found in large numbers on 

 the grounds examined. It is confined for the most part to the gravel 

 grounds in the neighbourhood of the Eddystone, but it was present in 

 only comparatively few hauls. It is recorded once from the Bolt Head 

 Shell Ground in haul 28. It is often found living in shells covered by 

 iSuherites doviuncula.
