FROM THE EDDYSTONE GEOUNDS TO START POINT. 449 



Distribution. Gcographiml, Kara Sea, White Sea, North Cape, Norway, Baltic, 

 North Sea, British Coasts to Mediterranean; Greenland, Labrador, Nova Scotia, Massa- 

 chusetts {fide Hartlaub, No. 38). 



Depth. To 300 fathoms (Sars, fide Allman, No. 2). 



Habitat. On shells and other hydroids (Hincks, No. 46, Schulze, No. 105). 



Gai-iipanularia fiexuosa. A hydroid was very abundant in haul 107 

 on the Bolt Head Shell Gravel (XVII.), growing on dead shells of 

 Pectuncidus glycimeris. The specimens were without gonophores, but 

 were identified independently by Mr. Browne and myself as C. flexuosa. 

 C. flexuosa was not taken in any other haul. 



Distribution. Hincks (No. 46) says it is confined to the littoral region, and is 

 extremely common on all parts of our coasts. Mediterranean (Carus, No. 14). 



Lovenella clausa. Growing on Tubularia indivisa, in haul 29, on the 

 Prawle Stony Ground (XVIII. ). 



Distribution. On stones in Torbay, 10 fathoms (Hincks). On Fuci from stony 

 ground off the coast of Sweden (Loven). Taken once at Heligoland (Hartlaub). 



Opercularella laccrta. Growing on Tubularia indivisa, in haul 29, on 



the Prawle Stony Ground (XVIII.). 



Distribution. Between tide-marks and in moderate de2)ths not uncommon. British 

 Coasts and Belgium {fide Hincks). 



Zafoea dumosa. The creeping variety of L. dumosa* was present on 

 practically all grounds, growing on shells and on other hydroids when 

 the latter were present. The branched variety (var. robusta) was 

 frequently met with, especially upon fine sand grounds, attached to 

 shells or polychaete tubes. The Neomenian Dondersia banyulensis 



was often found associated with this variety. 



Distribution. Geographical. White Sea, North Cape, eastern side of Atlantic to 

 Mediterranean (Pruvot, No. 98), Greenland, Alaska, Labrador and western side of 

 Atlantic, West Indies, Chili {fide Hincks, No. 46, and Hartlaub, No. 38). 



Depth. To 450 fathoms {Challenger, Allman, No. 3). 



Lafoca fruticosa. This species was taken occasionally on different 

 fine sand grounds (I., III., IV., VII.), and a fine colony was also found 

 in haul 84 on the coarse gravel and fine sand north-west of the Eddy- 

 stone (Ground XI.). 



Distribution. Geographical. North Cape, Iceland, Norway, British Seas {fide 

 Hincks), Strait of Magellan {Challenger, Allman, No. 3). 



Depth. To 100 fathoms (Iceland, Hincks). 



Habitat. On shells and zoophytes. 



Calycella syringa. This was recognised occasionally on the Bolt 

 Head Shell Gravel and on the Prawle Stony Ground, growing on Pccten 

 opercidaris shells, on Sertularia abietina, and on Hydrallmania falcata. 



Distribution. Geographical. White Sea, Iceland, Greenland, Alaska, North Sea, 

 British Coasts, north coast of France {fide Hartlaub, No. 38 ; and Hincks, No. 46), 

 Mediterranean (Carus, No. 14). 



* What we have regarded as the creeping form of L. dumosa has probably often been the 

 form recorded by other authors as Filclhcm serpcm, but we have not felt able to distinguish 

 between the two. We have often compared the IMymouth La/oca with Hincks' ligures of 

 Filellum scriMis, but up to the present have not seen anything like Filellum as figured.
