chelafa were picked off an Echums. During the " Hyaena" 

 expedition another similar case of Amphipoda Hving on an 

 Echinoderui had been met with when a number of females 

 and young males of Melka ohtusata were found on Asterias 

 ruhens. 



The following Annelids were obtained intliis " Spindrift" 

 expedition : — Lnmhrlnereisfrdgilis, Sthenelais llmicola, Mahn- 

 grema castanea, Syllis tulnfex, Splianrodorum flavum, Eunice 

 sp., Hermadlon pellucidum, and H. assim'de It is worthy 

 of remark that the two species of Hermadlon were in all 

 cases discovered as commensals with Echinoderms. One 

 specimen of H. pellucidum was picked off a Solaster, another 

 off an Astropecten, and a third off an Ophiurid, while ff. 

 assimile was taken from Echinus sphcera. 



On September 12th, Mr. Walker saw two very fine 

 living specimens of Palinurus vulgaris, the spiny lobster, 

 which had been caught at Valley in Anglesea. This is 

 believed to be the first record of its occurrence in Wales. 



Another expedition to the " central area" in the '' Spin- 

 drift" took place on September 27th. We hoped on this 

 occasion to be able to reach the ground where the very 

 large specimens of Fusus antiquiis, brought into market by 

 the Fleetwood trawlers, live, and for that purpose Mr. R. 

 D. Darbishire brought with him a Fleetwood trawler as 

 a guide ; but some time was spent in dredging on the way, 

 and although we eventually reached the proper region, we 

 were evidently not on the exact ground, as our dredges 

 and trawl failed to bring up any of the desired whelks. 



We tried on this occasion anew trawl, made on the pat- 

 tern of those recommended by Prof. A. Agassiz and by the 

 Prince of Monaco. The runners are double, and both 

 sides of the net are weighted, so that it is a matter of in- 

 difference which side the instrument falls on, and the 

 wooden beam is replaced by two iron bars, which can be
