very poor, comparatively few Copepoda and almost no repre- 

 sentatives of other free-swimming groups being obtained; 

 but Mr. Thompson noticed the relative abundance in all 

 the tow-nettings, both surface and bottom, during the day, 

 and also with the electric light at night and at dawn, of 

 unusually large specimens of Dias longiremis, and also the 

 prevalence of the somewhat uncommon Isias clavipes in all 

 the surface gatherings, though none were taken in the 

 bottom ones. 



Mr. "Walker reports that as regards the higher Crustacea 

 the results were rather poor. A few novelties, however, 

 were the Cumacean Eudorella truncatula, Bate, taken close 

 to Puffin Island with a small canvas dredge on the 

 previous day, a new species of Podocerus from near 

 Lleiniog, and Leptocheirus Mrsutimanus, Bate, taken in 

 the Straits, and also off Towyn. 



The dredging results during this day were good. The 

 following localities were explored: — (1) Porth Dafarch, 

 (2) Penrhos Bay, (3) two miles off Towyn Lodge, (4) be- 

 tween Towyn and Bhoscolyn Head, and (5) off Bhoscolyn 

 Beacon, where we had six hauls. Some very fine Sponges 

 were obtained, and Ascidians (six species) were plentiful. 

 One patch of rich ground was discovered near Bhoscolyn 

 Beacon, where Antedon rosacea, in the " pentacrinoid " 

 and also in the adult state, was brought up in abun- 

 dance, along with various Tunicata (Ascidia virginea, and 

 A.venosa), Holothurians, Nudibranchs (Cratena viridis and 

 Doto fragilis), Zoophytes, Polyzoa, and especially large 

 Sponges. Altogether this expedition was, probably, more 

 prolific in regard to Sponges than in any other group. 



Dr. Hanitsch tells me that, in addition to a number of 

 commoner species, we obtained in that one day (May 25th), 

 in the dredgings in Penrhos Bay, off Towyn, and off Bhos- 

 colyn Beacon, specimens of Raspailia ventilabrum, Poly-
