TRANSACTIONS OF THE SECTIONS. 121 



complished in boats ; but being provided with tents &c., tlie party -was enabled to 

 spend a few daj's at numerous stations on the shores, at distances varying from ten 

 to fifty miles apart. 



The total number of species obtained, not including- Nudibranchiates, amounted 

 to about 818, of which Gl9 have been identified or described. In the list of named 

 species about 355 were not previously recorded as inhabiting the lied Sea, of which 

 53, including 3 genera, are new to science. 



In a recent work by Professor Issel, 640 species of MoUusca, including Nudi- 

 branchiates, are enumerated as the total number recorded from the lied Sea 

 (including some doubtful), of wliich 191 were collected by himself in the Gulf of 

 Suez. 



The extraordinary dissimilarity between the fauna of the Red Sea and of the 

 Mediterranean, which has been frequently noticed, appears to be confirmed by 

 further researches ; and although it is remarked by Issel that some of the Suez 

 species seem to be so nearly related to their representatives in the MediteiTanean 

 and Atlantic that they may easily be supposed to have been oiiginally the same, 

 and that their distinguisliiug characters may have been acquired during the series 

 of ages through which they Lave been separated, such species compose but a small 

 percentage of the whole, and it is by no means certain that more remote localities, 

 such as Japan and Australia, especially the former, do not fui-nish about as many 

 examples of relationship to the Em-opean fauna. 



The most important object of the report was to throw light upon the geogi'aphical 

 distribution of Mollusca ; but for this it would be required to publish at length the 

 list of the species with the other localities at which they are recorded to have been 

 found. It would then be shown that the number of Suez species common to Japan, 

 the Philippine Islands, Australia, the Sandwich Islands, &c., prove a much wider 

 distribution of the MoJlusca of the Pacific and Indian Oceans than of those of the 

 Atlantic, where the shores of America possess but few species in common with the 

 coasts of Europe and "West Africa. The fact of a species in several instances having 

 been obtained from only two localities very remote from each other, such as Suez 

 and Japan, is a proof of the very small amoimt of knowledge we possess of the 

 fauna of the intervening seas. 



Preliminary Beport on certain Annelids dredged in tite Expedition of H.M.S. 

 'Porcupine ' (1869). By W. C. M'Istosh, M.D., F.L.S. 



The specimens were chiefly procured from water under 500 fathoms, off the coast 

 of Ireland. Amongst the few specimens of Nemerteans no new form occurs. The 

 Annelids are on the whole of a northern type, many of the race having been pre- 

 viously procured by Mr. Jeffreys oft' the Shetland Islands, and well known in the 

 northern seas generally. There were several new and most interesting species, 

 including a Sthenclais, a form allied to Lecmira, but probably requiring a new genus 

 for its reception, a Eunice, Kothria, and C'Ji(stoffone. The Antinoii sarsi of Kinberg 

 and the Pctfa pusilla of Malmgren were, besides, added to our fauna.
