40 THE VICTORIAN NATURALIST. 



D'Orbigny — two very fine living examples were obtained and six 

 single valves of dead specimens. Other shells seemed scarce, 

 Macoma Marice, T. Woods, being the only other obtained alive at 

 this spot, while dead shells of Dosinia grata, Chione striatissima, 

 Tellina (Arcopagia) deciissata, Cytlierea J)iemenensis, Cardita 

 biniaculata, Chione lamellata, Natica conica, and Ferisiernia 

 Paivce were also to be seen. Coming in closer to the land vve 

 left the muddy bottom and got on to a rocky bottom, on which we 

 remained until some distance round Rickard's Point. From the 

 dredging here a very fair number of living examples of several 

 species were secured. By far the commonest shell in the dredge 

 from this ground was Mytilus cltorus, and though specimens of 

 this shell were not much sought after, it not infrequently had 

 attached to it several more interesting forms of molluscs, the com- 

 monest being Crepidula unguiformis, Galyptroia calyptraj'ormis, 

 and Hipponyx Australis. A large number of Turbo aureus were 

 attached to the pieces of stone brought up, as also were specimens 

 of Clanculus plebems. A few fine examples of Fasciolaria 

 coronata were hauled up, and one dead example of this species 

 had no less than ten specimens of Crepidula xinguiformis in the 

 mouth of the shell, while the inside was tenanted by a fair-sized 

 Hermit Crab, and the outside acted as a basis of attachment for 

 Hipponyx Australis. Murex triformis was also found living, and 

 an interesting feature in connection with this was that the 

 operculum was covered by an almost exactly equivalent-sized 

 Crepidula unguifo7'mis. The other living species obtained were : 

 — Rapldtoma anomala, Ceritliiiim dubium, lUialoiia (?),sp., 

 Haliotis ncevosa (?), Chamostrea albida, Barbatia Carpenteri, 

 Modiolaria Cumingiana^ Venerupis (?), sp. We then went about 

 a mile or so further from the shore, and again the dredge showed 

 a muddy bottom. In the molluscan line nothing of special note 

 occurred ; a few living examples of Cytherea Diemejiensis and 

 dead shells of Pecten laticostattis were to be seen. Nothing 

 worthy of note was obtained off Brighton, though dead shells 

 were extremely numerous." 



We were successful in obtaining more of the diatomaceous 

 material mentioned in my report two years ago, and from which 

 Messrs. W. M. Bale and H. Grayson have now obtained over 

 ICO species, thus proving it to be by far the richest deposit of 

 these interesting forms on the Australian coast. Mr. H. 

 Grayson has promised to read a detailed account of the deposit 

 before a meeting of the Club, and as much of the other material 

 obtained requires time for working out it is proposed on an early 

 date to make a special exhibit of the results of the dredging. 



The Brighton contingent of the party were accommodated on 

 board the yacht Starlight, kindly placed at their disposal by Mr. 

 C. J. Cottell, and were under the leadership of Mr. J. Shephard, 

 who reports as follows : —
