12 MAUisa Zoology. 



store! mind dil much to aU to tha social geniality of the party, it is 

 thought thiit a record of the Dredgiiigs may not be uiiintoresthig here, 

 accomi)auieil by some suggestions for another excursion during 1878. 

 "VVhtn wo arrived at " the Island of the Many Peaks," much difficulty 

 was experienced in obtaining a suitable boat, hut eventually we made 

 arrangements with the "Cutty Sark," a herring smack, and the 

 " Mona," a small yacht, both of which did tho work very well. The 

 Dredgings, which commenced at tlie neap tidt's succeeding the August 

 full moon, were carried on for a week principally in Lamlash Bay, but 

 we had several good hauls both in the Bays of Brodick and Drumadoon. 

 The depths did not exceed about twenty-five or thirty fathoms, and thus 

 it was not found necessai-y to talie temperatures, although we had jiro- 

 vided ourselves with one of Ne'gretti and Zambra's " Deep Sea 

 Thermometers," in addition to the " Miller CasoUa " which we used 

 before, both of which worked well. The results were officially reported 

 to the Society on our return by Dr. Marshall and tho writer, at a 

 General Meeting, held on the I8tli September last. Mr. John Morley, 

 tho Hon. Sec, also alluded to the Botanical excursions which were made 

 under his guidance, and that of the Pi'esideut, Mr. E(hiiund Touks, B.C.L. 

 On the present occasion it is not, therefore, proposed to give more than 

 a brief account of the more interesting forms of marine life taken. 



The ground which we went over has long been a favourite spot with 

 marine naturalists. Among others of eminence who had been there, we 

 wore informed that tlie late Dr. Ijandsl)orongli had, witli Major 

 Martin, dredged the locality for five years. Our hopes of taking any 

 novelty were not therefore vei-y great. Nevertheless, on refen-ing 

 to the lists in the chapter on Marine Zoology in Dr. Bryce's 

 book, " Arran and other Clyde Islands, " (4th edition, 1872.) a 

 charming volume, which should be in the hands of all natunilists visiting 

 •the Inland, we have reason (to believe that two forms, TIn/oiic and 

 J-'li/sia — to be hereafter referred to— have been added by us to the local fauna. 

 'Tlie distribution of marine life was extremely local. Within a few yards 

 •each haul of tho dredge usually brought up an entirely different scries of 

 animals. Sometimes these consisted of the rosy feather star — sometimes 

 of brittle stars— another haul would contain Pectcns only — another the 

 nest-building bivalve, TJnui )iitni!< — another the common egg urchin 

 Krhiiiwi sphd-ni — another vielded foiu- beautiful specimens of Prideau.K'a 

 }lvri\\\t cnih, ( Pii!iuru>< I'ritloiK.rii, ) with its "commensal," the Cloaklet 

 anemone (Adinnxid ivdlintii) — another woukl l)e of Mi'lobcuia calrarfa, n, 

 curious coralline, largely composed of calcareous matter, prettily colcui'etl 

 purple or pink when living, but speedily becoming white after taken from 

 the sea. Sometimes tlie dredge woukl contain nothing but mud or sand 

 — to the gi'cat disappointment of tho dredgers— and on one occasion 

 a co7imion wine buttle came up. It was brought from about twenty- 

 five fathoms, was unbroken, full of sand, and covered with specimens of 

 l'i)lij:oa and Ili/drozan. As at Teignmouth, in tlie yeai' 187;{, we were too 

 late to observe the developmental processes in the Ili/drozoa ; but it was 

 an interesting fact that, although in point of date we were synchronous 

 with tlie Teignmouth exciu'sion, when we took several stalked forms of 

 tho rosy feather stsu', (.[utrdoti (('(imittiiln) ronaceux,) not a single specimen 

 was obtained in Lamlash Bay, although every frond of Laminaria 

 dredged was diligently searched. Numbers of the adult form wero taken 

 in many varying shades of inchness of colour. On tho whole, our best 

 prizes were in Erhinodennntu and Mollusca, but there were several objects 

 of interest in other classes. For instance, in I'orifcni wo took specimens of 

 the little calcareous sponges, (Innitiu compirKsa and G. ciliata ; in Zoophyta, 

 a fine mass of Antomuhirin ritiiuixd ; but with tho exception of the four 

 l)eautiful specimens of the Cloaklet anemone, {Aduiii^iii pnUiala,) before 

 alluded to, no other anemones of interest were drudged, nor any corala.
