MAKINE BIOLOGICAL STATION ON PUFFIN ISLAND. 45 



chelata were picked off an Echinus. During the " Hyaena" 

 expedition another similar case of Amphipoda living on an 

 Echinoderm had been met with when a number of females 

 and young males of Melita obtusata were found on Aster ias 

 rubens. 



The following Annelids were obtained in this " Spindrift" 

 expedition : — Lumbrineveis fragilis , Sthenelais limicola, Malm- 

 grenia castanea, Syllis tubifex, Sphcerodorum fiavum, Eunice 

 sp., Hermadion pellucidum, and H. assimile. It is worthy 

 of remark that the two species of Hermadion 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 H. 

 assimile was taken from Echinus spJicera. 



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

 living specimens of Palinuru's 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 antiquus, brought into market by 

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

 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 a new 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
