FROM THE EDDYSTONE GROUNDS TO START POINT. 483 



"reamy" bottom (sand and mud), in 30 fathoms ; on dead shells and sand, 22 and 

 25 fathoms; on stones and mud, 19 fathoms (Herdman, No. 40, Vols. VIII. and IX.). 



Pectinaria auricoma (Table VI.). Single specimens of a Pedinaria 

 with a curved tube, identified by Mr. Hodgson as P. auricoma, are not 

 unfrequently met with. They have occurred on Grounds VII. and VIII. 

 (fine sand with shells) and X. and XII. (coarse gravel and sand) in the 

 neighbourhood of the Eddystone, on the Bolt Head Shell Gravel (Ground 



XVII.), and the Prawle Stony Ground (XVIII.). 



Distribution. Geographical. North and West Norway, North Sea, British and Irish 

 Coasts, Mediterranean [fide Michaelscn]. 



Depth and Bottom-deposit. M'Intosh [No. 81] found Pectinaria auricoma in the 

 Shetlands at depths from 50-100 fathoms ; Haddon [No. 34] off the south-west of 

 Ireland on coarse sand in 35-40 fathoms ; Mobius [No. 87] in the Ponimerania dredg- 

 ings generally on sandy mud, occasionally on coarse ground from 12 fathoms to 217 

 fathoms. In the North Sea also Michaelsen [No. 79] obtained it generally on mud and fine 

 sand, occasionally on coarser ground. In the Kattegat Levinsen [No. 66] records F. 

 auricoma from 12^ to 17 fathoms on mixed deposits (sand or gravel with mud). In 

 the Liverpool district Hornell [No. 49] found P. auricoma rarely in 20-22 fathoms, whilst 

 P. hclgica was common from low-water to 21 fathoms. 



Polymnia nehulosa (Table VI.) occurred in small numbers on the 

 gravel grounds around the Eddystone (IX., XIII., and XIV), and on 

 the sand ground (VII.) immediately to the south of these. 



DiSTPJEUTiON, West Norway, British Coasts, West France, and Mediterranean {fide 

 Michaelsen, No. 79). 



Nicolea vemistula (Table VI.). Occasional specimens almost entirely 



confined to fine sand grounds. 



Distribution. Greenland, Iceland, Faroe, Sjiitzbergcn, Nova Zembla, Siberia, Norway, 

 British Coasts, French Coasts, Mediterranean, Red Sea [fide IMichaelsen, No. 79, and 

 Saint- Joseph, No. 102]. 



Depth, etc. 2-15 fathoms (Saint-Joseph) ; 20-22 fathoms (Hornell). On zostera 

 (Michaelsen); on Eijtiphlaea innastroides (Saint- Joseph). 



Thelepus sp. (Table VI.). A species of Thelepvs is very common on 

 the grounds investigated. Relying on the character of the uncini it 

 would seem to be T. sctosas, Saint-Joseph. The differences between this 

 species and the common T, cincinnatus are, however, so slight that there 

 is probably much confusion between the two in the literature. In the 

 account of the distribution I therefore give that for each of these 

 species. 



On "the Eddystone Grounds Thdcpus is very common on all the fine 



sand and also on the coarse gravel to the west of the rocks. On the 



coarse gravel south-east of the Eddystone (Ground XIII.) it was not 



taken, and only an occasional specimen on the fine gravel of Ground 



XIV. was seen. It was not present on the clean shell gravel (XVI.), 



nor on the Bolt or Prawle Grounds. 



DisTiiiBUTiON. T. setosus, Saint-Joseph, has been recorded only on the north coast of 

 France (Saint-Joseph, No. 102) at depths of from 2 to 15 fathoms. T. cincimiatua, Fabr.
