and A. hisjnday Phoxichilidiwm femoratum, Phoxi- 

 chillis spinosus, 

 MoLLUSCA. — Doto coronata, Doto fragilis, Eolis gracilis, 

 Mytiliis barbatuSf Anomia patelliformis, and Sepiola 

 atlantica. 

 Later on in the day, in the Menai Straits, nearly opposite 

 Bangor, at a depth of about ten fathoms, the small red 

 Ascidian, Styela grossularia, was obtained in quantity. 

 Specimens of Ascidia virginea, Polycyclus savignyi, and 

 Alcyonidiuni gelatinosum were also obtained in the Straits, 

 along with many dead shells. 



On the morning of the 25th, the third day of the cruise, 

 a few hauls of the dredge were taken in fourteen fathoms, 

 between Puffin Island and Anglesea. In this channel, 

 Ophiothrix pentaphyllum must be very abundant since it 

 came up in dredgefuls. Amongst the Mollusca obtained 

 here were : — Modiola harbdta, Sj^henia hinghami, Scrohicu- 

 laria prismatica, Scrohicidaria alba, Tellina donacina, Saxi- 

 cava rugosa, Cardium norvegicum, and Eledone cirrhosa. 



The trawl was then let down off Ked Wharf Bay, on the 

 north coast of Anglesea, but resulted in little worthy of 

 note except Dentalium entale and a large specimen of 

 Eolis picta. On the way back to Liverpool, a few hauls 

 were taken in fourteen fathoms, about six miles to the north 

 of the Grreat Ormes Head. Here a large specimen of 

 Astropecten irregularis was obtained, with the rare Annelid 

 Malmgrenia castanea * as a commensal in one of the 

 ambulacral grooves. Amongst the other species observed 

 were : — 



Hydroida — Garveia nutans, Campamdaria verticillata, 



Sertularella polyzonias and Sertularia opercidata, 

 PoLYZOA. — Vesicidaria spinosa. 

 Tunicata. — Botrylloides rubrum.
