Arnoglossus latenia (Scaldback). In 34 

 only. 



Zeus faher {Johii Dory). One in 77 only. 

 Trigla gurnardus {G'rcy Gurnard). One 

 in 77 only. 

 ■ „ lineata {Parrot Gurnard). Five 

 specimens in 77. 



Trigla liiiundo (2'ub Gurnard). One in 



77 only. 

 Callionymns lyra {Dra/jonct). A few only. 



Gobius JefTreysi {Jeffreys Goby). Many 

 amongst Cellaria, etc. 



Rliina squatina {Monk). One small one 

 in 77 only. 



Ground V. 



Four miles N.E. f N. of Eddy stone. 



Haul 90 (otter-trawl). 



It has been necessary to consider this haul separately from 

 Ground III., as both the bottom-deposit and the fauna show several 

 important differences. 



Bottom-deposit. The sand has the following texture : — 



II. Coarse Gravel ... ... ... 27 per cent. 



Medium Gravel 

 Fine Gravel 

 Coarse Sand 



III. 



IV. 



V. 



VI. 



VII. 



VIII. 



Medium Sand 

 Fine Sand 

 Silt

The sand is therefore at the same time coarser and more muddy than 

 that of Ground III. 



[90. Average grade of sample, 6'561. Percentage of carbonate of 

 lime in whole sample, 22*91. Highest percentage occurs in IV., which 

 contains 57'o0 per cent. This is one of the fine-textured deposits, in 

 which VII. constitutes more than 50 per cent, of the whole, and 

 shows the low percentage of carbonate of lime which characterises 

 these fine-texture sands among the present series of samples. 



Geologically 90 is parted from all the other samples by a very wide 

 distinction indeed. Eoundly speaking, 80 per cent, of the identifiable 

 rock materials are Devonian and only 20 per cent. Triassic. No 

 Eddystone reef material is present. No other sample presents more 

 than 15 per cent, of Devonian rock. 



In 90 VI. Foraminifera are comparatively scarce, in 90 VII. they are 

 numerous, 104 individuals were counted in 0'13 grams (2 grains), 

 or 800 per gram. The following species are present, arrangement 

 as before : — Rotalia heccarii, Miliolina seminulum, Lcujcna orhignyana, 

 Bolivina dilatata, Textularia gramen, Diiporhina rosacea, Truncatu- 

 lina lohatula. In all, seven species. — R. H. W.] 



There are few unbroken shells. 



Burrowing species. The abundance of Aphrodite acideata forms a
