fossil), Pleuronectia sp. n., Actceon sp. n., besides Limopsis borealis, L. 

 aurita, Bentalium abyssorum, Puncturella noachina, Hela tenella, Rissoa 

 Jeffreys!, Natica Montacuti, Admete viridula, Pleurotoma carinata, and 

 other northern species. Crustacea : Mr. Norman reports as to the 690 

 fathoms (No. 3), "A most important dredging; the results among the 

 Crustacea being more valuable than all the rest put together — at any rate 

 of the First cruise. It contains almost all the choicest of the new species 

 in last year's expedition, and four stalk-eyed Crustaceans of great interest, 

 three of which are new, and the fourth (Geryon tridens) is a fine Norwe- 

 gian species." And he adds that " with these are associated two forms 

 of a more southern character, Inachus Dorsettensis and Ebalia Cranchii, 

 which I should not have expected at so great a depth." Echinodermata : 

 Oidaris papillata (from which, according to Professor Wyville Thomson, 

 C. hystrix is not specifically distinct), Echinus elegans, Astropecten arcticus, 

 A. Andromeda, A. Pareli, and A. irregularis. Annelida : Dr. M'Intosh 

 notices, as a species supposed to be specially northern, Thelepus circin- 

 natus of Fabricius from 690 and 500 fathoms. Hydrozoa: a new and beau- 

 tiful tree-like form of a deep orange-colour. Spongia : Holtenia Carpen- 

 teri in considerable numbers and of all ages. Professor Wyville Thomson is 

 fully convinced that the H. Grayi of Kent is only a variety of this species. 

 The dredges did not fill ; and most of the above results were obtained by 

 means of the "hempen tangles," which were in 1869 for the first time 

 attached to the dredge, and used with such wonderful success. 



7. July 9th. Dredged all day ; but the wind was too light, and the drift 

 therefore insufficient for effective work. We began dredging in 71 7 fathoms 

 (Station 4), and afterwards shifted the ground, getting 358 fathoms 

 (Station 6), when we left off. This was about 185 miles from Cape Clear 

 and Ushant, and 165 miles from the Scilly Isles. The Fauna was generally 

 of a northern character, and included among the Mollusca Terebratella 

 Spitzbergensis (Arctic and Japanese), Pecten vitreus, P. aratus, Leda per- 

 nula, Axinus eumyarius, Rissoa turgida, Trochus suturalis (a Sicilian fossil), 

 Odostomia nitens (Mediterranean), Taranis Morchi, Defrancia sp. n., and 

 Pleurotoma hispidula or decussata=P. concinnata, S. Wood (Sicilian fos- 

 sils, the last being Coralline Crag also), Ringicula ventricosa, Actceon sp. n., 

 and Bulla propinqua. Some species were common to the North Atlantic and 

 the Mediterranean. Among the Echinoderms was a fine specimen of Bri- 

 singa endecacnemos ; and the Corals were represented by Amphihelia oculata 

 and Desmophyllum crista-galli. Among the Annelids were Pista cristata 

 of O. F. Miiller, and Trophonia glauca of Malmgren, both Arctic species. 



8. We lay-to on Sunday the 10th ; and the next day we resumed our 

 soundings and dredgings on the Channel slope at depths ranging from 

 257 to 690 fathoms (Stations 8, 9), occasionally changing the ground. 

 The Fauna was everywhere northern, with a few exceptions. As to the 



Mollusca may be mentioned Terebratula septata (intermediate in shape 

 between the typical kind and Waldheimia Floridana),Leda{Yoldia) obtusa,
