NARRATIVE OF THE CRUISE. •_'<;!) 



A collection of the terrestrial Invertebrata of this group was made, which has not 

 yet been entirely worked out, but up to the present time it has yielded the following : — 

 Mollusca, 1 Balca (Tristania) ventricosa, Gray, and Balea {Tristania) tristensis, Gray, 

 previously known to inhabit these islands, and in addition Limax canariensis, d'Orb., 

 Li max gagates, Drap., Helix (Hyalinia) exulata, Smith. 



Coleoptera, 2 Lancetes vaiiiu, Fabr., Cercyon littorale, Gyll., Qnedius fulgidus, Fain., 

 Palcechthus glabratus, Waterhouse, Palcechthus cossonoides, Waterhouse, and Pentarthrum 

 carmichaeli, Waterhouse. Rev. 0. P. Cambridge has recognised the following spiders 

 from the collection : — Tegenaria derhamii, Scop., Steatoda versuta, Bl., Linyphia leproea, 

 Old. (European species, the two last British), from Tristan Island, and Theridion sp. ? 

 (allied to Theridion formosum, Clk., a widely-spread European species), Steatoda versuta, 

 BL, Neriene sp. ? (probably new, but scarcely in good enough condition for description), 

 from Inaccessible Island. In addition to these Dr. v. W. Suhm notes in his diary : — 

 " Jidus and Scolop>e7idi u common everywhere; two specimens of a bug underneath the 

 bark of trees in Inaccessible Island, and a small whitish Cicad, Nightingale Island. 

 A Noctuid from Nightingale Island, also seen on Inaccessible Island ; caterpillars, 

 probably of a Vanessa (?), Microlepidoptera. Musca sp. ; a Culex-like animal was seen 

 but not obtained ; Pidex parasitic in the nests of Penguins and Albatrosses on 

 Nightingale Island. A Thysanurid was found on a dead Puffin. No Orthoptera nor 

 Hymenoptera were found. Oniscus, Gammarus everywhere under stones, as also 

 Lumbricus." 



Many hauls of the dredge and trawl were taken around and between the islands of 

 the Tristan da Cunha group in depths from 60 to 1100 fathoms. There was generally 

 a coarse shelly bottom, composed of fragments of Polyzoa, Lamellibranch and Gasteropod 

 shells, Brachiopods, Echinoderms, Pteropods, Serpulce, and a few pelagic and other 

 Foraminifera. The mineral fragments were exclusively of volcanic origin. A large 

 number of animals of all groups came up in the trawl and dredge : Primnoas, Gorgonias, 

 Caryophyllias, Hydroids, Sponges, Starfish, and Molluscs ; altogether a mass of material 

 much like what is found in shallower water off the coast of Great Britain. 



The Cephalopoda. — On the return of the Expedition to England the collection of 

 Cephalopoda was sent to Professor Huxley, who hoped to be able to prepare a Report 

 on the whole of this group. In 1882, .owing to the many demands on his time, Professor 

 Huxley decided to limit his Report to the genus Spirula, and the remainder of the 

 collection was handed over to Mr. W. E. Hoyle for examination, who writes as follows : — 



" Regarded as a whole, the collection of Cephalopoda is quite as remarkable for 

 its deficiencies as for the types represented in it. It might have been expected
