FKOM THE EDDYSTONE GROUNDS TO START POINT. 455 



ou the fine gravel of Ground XIV., the coarse gravel mixed with sand 

 of Ground XL, and on Ground VII. It is only occasionally met with 

 on Grounds X., XIII., XV., and on the Bolt Head Shell Gravel (XVII.) 

 and Prawle Stony Ground (XVIIL). 



On the whole the species, in the area examined, seems to flourish 

 best in the coarser sand grounds, being scarce on gravels and stony 

 ground, and also on very fine sand. 



Distribution. Geographical. British Coasts, Belgium, Bay of Biscay {fide Hincks, 

 No. 46), Mediterranean (Pruvot, No. 98), western side of North Sea [Pommcrunia). Not 

 recorded at Heligoland (Hartlaub, No. 38), nor in Kattegat (Levinsen, No. 66). 



Habitat. Commonly on a sandy bottom (Hincks). Schulze (No. 105) records it three 

 times in the Fommerania dredgings on coarse ground, three times on sand and shell. 



Antennularia ramosa (Chart IV.). Generally on the same grounds 



as A. antennina, but never so abundant. It was most numerous on 



Grounds VI. and XII. This species also fixes in the sand by a 



felt-work of root-fibres. 



DiSTRiBTJTiox. British Coasts, South Africa {fide Hincks, No. 46), North Sea, 12 50 

 fathoms (Schulze, No. 105). In the Pommerania dredgings it was recorded on sand, on 

 sand and shell, and on small stones. 



Aglaophenia myriophylhim (Chart II.). Like Antennularia antcn- 

 nina and ramosa this species fixes itself in the sand by a felt-work 

 of fine root-fibres. It confines itself much more entirely to this mode 

 of attachment than Antennularia, and I have never found it growing 

 on shells, stones, or polychaete tubes. Probably in consequence of this, 

 A. myriophylhim is much more restricted in its distribution. On the 

 Eddystone Grounds it was most common on the fine sand of Ground 

 III., north-east and east of the rocks. It was constantly present on 

 the adjoining sand (Ground IV.), and also on the coarse gravels mixed 

 with fine sand or mud of Grounds XL, XII., and XIII. It was rare or 

 absent on the remaining gravel and sand grounds in the neighbourhood 

 of the Eddystone. On the fine sand of the inner and outer trawling 

 grounds (I. and II.) it was only present in one haul, viz., haul 82.* 

 It was absent on the Bolt Head Shell Gravel (XVIL), and was only 

 once met with (in haul 29) on the Prawle Stony Ground (XVIIL). 



Distribution. Geographical. British Coasts, Mediterranean, Gulf of St. Lawrence, 

 Massachusetts Bay {fide Hincks, No. 46). 



Depth. Chiefly from dee}) water (Hincks). 364 fathoms (Allman, Porcupine, No. 4). 



Aglaophenia tuhulifera. This species has only been taken twice ; 



once fixed to a specimen of the Ascidian Polycarpa varians, in haul 55 



(Ground X.), and once in haul 99 (Ground XVI., probably on a stone). 

 Distribution. Geographical. British Seas, South Africa {fide Hincks, No. 46). 

 Depth. In moderately deep water (Hincks). 

 Habitat. On sea-weeds, zoophytes, sliells, etc. 



* It will be noticed tliat this haul is exceptional also in the ])resence of Haleduin 

 halecinnm and of fragments of Chactoplcrus tubes. There is probably some coarse ground 

 near it, the influence of which is being felt {cf. p. 391).
