but new to this locality. On this occasion also the cysto- 

 carps of Cnteiiella <>j>ini/ia, which have; been seldom seen 

 before, were found in abundance. 



Zoophytes, Annelids, &c. 



Before the ''Hyaena" dredgino expedition in May, a 

 party of eight members of the Committee and others, in- 

 cluding Mr. George Brook, F.L.S., Lecturer on Embry- 

 ology in the University of Edinburgh, worked at the 

 station ; and a week later Mr. J. Hornell, who had been 

 on the ''Hy?ena" trip, left the rest of the party at 

 Bangor and then devoted some time to the investigation 

 of the Annelids first of the mud flats about Garth, where 

 he found several species new to the district, and secondly 

 at Puffin Island. Amongst the most notable forms col- 

 lected on this occasion by Mr. Hornell were Dasychone 

 lucullana, Serpula reversa, Si(jalion boa, Troplionia phnnosa, 

 Phyllodoce lamlnosa, FlahelUgera affinls, Scoloplos armiger 

 and a specimen of the curious and aberrant Spharodorum 

 flavum. The most abundant Polychaeta on tlie shore at 

 Puffin are Eidalia v'mdis, Nereis pehu/ica, Polynoe lagisca, 

 and a Cirratnlus. The Gephyrean worm Phiscolosoma 

 vuJgare also occurs in mud under stones on the south Spit 

 (October 26th, 1890). 



Mr. Chadwick collected at Beaumaris and at Puffin 

 Island towards the end of June, and had a couple of days 

 dredging from the Turbot Hole upwards to the straits; 

 and Mr. J. A. Clubb and others did some work at the 

 station in August. Mr. Chadwick dredged a fine Chdlna 

 oculata, eight inches in height, four examples of Pllumnus 

 hirtellus each ensconced within a separate w^ielk shell, 

 many Clavelhia lepadiformk, which is very abundant near 

 Beaumaris, and some Cucumaria plauci which have since 

 reproduced by transverse fission in captivity, three of them
