FROM THE EDDYSTONE GROUNDS TO START POINT.

Ground VIII. 



Eddystone S.E. | S., about one mile distant. 



Haul 48, (Dr.) with 89 B (?) C-dr. 



Haul 48 resembles in all the characteristic features of its fauna the 

 hauls made on the fine sand of Ground VII., and it is therefore 

 necessary to separate it from Ground XIV., which adjoins it on the 

 southern side. As in the case of Ground VII. the fauna is clearly 

 very much influenced by that of XIV., but the abundance of Cellaria, 

 the nature of the hydroid fauna, the presence of Falmipes placenta, all 

 point to a fine sand deposit. It is not unlikely that the dredge passed 

 over more than one kind of bottom-deposit. 



That a fine sand deposit does exist in this neighbourhood was shown 

 by a sample taken with the canvas dredge at the conclusion of haul 89. 

 The latter haul (Ground X., see p. 417) was composed almost entirely 

 of Ophiothrix fragilis, but when at the end of it the canvas dredge was 

 used, it came up full of fine sand, and with no specimens of the 

 ophiurid. This sample has been numbered 89 B. That the ophiurid 

 ground had been passed when it was obtained I have no doubt, as in all 

 cases where the canvas dredge has been used on grounds where 

 Ophiothrix was very abundant, both on the Eddystone grounds and in 

 other localities, a very large number of specimens of the species came 

 up with the sample of deposit, and the latter was always muddy gravel. 



The composition of the sample 89B is therefore given here : — 



II. Coarse Gravel ... ... ... 1*3 per cent.

[89B. Average grade of gample, 6-386. Percentage of carbonate of 

 lime in whole sample, 4861. Highest percentage occurs in VI., which 

 contains 62"73. This is one of the fine-texture deposits, in which the 

 percentage of grade VII. to whole sample rises above 50 per cent. 



In 89 B VI. Foraminit'era were numerous, thirty-eight individuals 

 being counted in 0-16 grams (2| grains), or 237 per gram. In 

 89B VII. Foramiuifera were very numerous. The following are the 

 species found, in order of frequency: — Rotalia beccarii, Miliolina seminu- 

 lum, Truncatulina lohatula, Tcxiidaria gramen, Textidaria agglutinans, 

 Discorhina rosacea, Planorhidina mediterranensis, Lagena sulcata, Mdio- 

 lina trigonula, Miliolina hicornis. In all, ten species. — II. H. W.] 



No shells were present in the sample.
