510 ox THE FAUNA AND BOTTOM-DETOSITS NEAR THE 30-FM. LINE 



very scarce on the fine gravel of Ground XIV. As this latter was a 

 very rich ground, the ahnost entire absence of whelks is noteworthy. 



Distribution. Geographical. Both sides of the North Atlantic from the North Cape 

 and Iceland to Roclielle and Massachusetts. In the stomach of Trigla gurnardus in the 

 Gulf of Lyons {fide Jeffreys). 



Depth. Low-water to 180 fathoms (Porcujnnc, fide No. 33). 



Bottom-deposit. Forbes (No. 24, Brit. Assoc, 1850) records Buccinnm undatum from all 

 kinds of bottom-deposits, and the other authors agree with this. Heincke (No. 39) says 

 that near Heligoland it is specially conmion on sandy mud and on pure mud. Petersen 

 (No. 95) found it common all over the Kattegat. The animal is able to burrow in sand 

 (Jeffreys). 



Fusus islandicus { = F. gracilis of Jeffreys). Taken only in hauls 105 

 and 107 on the Bolt Head Shell Gravel, where several living specimens 

 and a number of shells were obtained. 



DiSTRiRUTiON. Geographical. A northern species. White Sea (?), Russian Lapland, 

 Iceland, Faroe Islands, Norway, Sweden, Kattegat,* British Seas, North of France, Loire- 

 Inferieure. Rare in the South of England, common on northern fishing banks (Jeffreys). 



Dep)th. 20-145 fathoms (Jeffreys). 



Bottom-deposit. Forbes [Brit. Assoc, 1850) found it on shell, on stones, on sandy gravel, 

 and on sand ; Metzger on sandy mud, and on sand, shells, and stones. 



Cypraea europaea (Table VI.). Not uncommon in the neighbourhood 

 of the Eddystone, on the coarser sand grounds, and on the Prawle Shell 

 Gravel, especially amongst hydroids and Cellaria. 



Distribution. Geographical. Drontheim to Gibraltar and Mediterranean (Jeffreys). 



Depth. 0-100 fathoms. 



Bottom-deposit. Forbes (No. 24, Brit. Assoc, 1850) gives ten records, all on coarse 

 ground, and Gwyn Jeffreys says the species occurs on stony and coral grounds. Metzger 

 (No. 77) gives two records, one on stony ground and one on sand. 



Ovula patula (Table VI.). Single specimens were taken on Grounds 



II., VIII., and XVIII. The species is generally found on Alcyonium 



digitatum. 

 Distribution. Geographical. British Coasts, Gulf of Lyons (?) (Jeffreys). 

 Depth. Coralline zone (Jeffreys). 

 Bottom-deposit. On Alcyonium (Forbes and Hanley). 



Dondersia hanyulensis, Pruvot. A few specimens of this species, 

 which is very conspicuous owing to its bright red colour, were obtained 

 always upon colonies of Lafoea dumosa. It is recorded on Grounds 

 III., IV., and X. 



The species was first described by Pruvot (No. 97), who found it 

 always on Lafoea dumosa. It is relatively abundant at Banyuls, in the 

 Mediterranean, in 25-165 fathoms, and a few specimens were obtained 

 at Roscoff, in Brittany, in 44 fathoms. 



Proneomenia aglaopheniac (Kowalevsky et Marion). This Neomenian 

 was met with not unfrequently coiled around the stem of Aglaophenia 

 myriophyllum, though it was present on only a small proportion of the 

 total number of specimens of the hydroid which were taken. It is 

 recorded on Grounds III., VII., VIII., XL, XII. 



* Petersen does not record it. Jeffreys gives it on the authority of Jonas.
