THE MAEINE BIOLOGICAL STATION. 383 



already known to us. From what little examination we liave made, 

 Toraminifera are likely to farnisli a great many species for investiga- 

 tion. On this head, I expect that we shall know more hefore long, 

 as an English gentleman, Mr. A. Darrand, who spent a week in 

 the station, sent to England bottom- washings from Misaki to be 

 examined by specialists. Of the Radiolarians we have seen some — 

 mostly of the Acanthometridae. Sponges are well represented. 

 Of these, the most renowned is of course Hyalonema. We have not 

 yet had the pleasure of bringing this beautiful sponge up by our- 

 selves, as we do not possess at present means for dredging in deep- 

 sen, but the fishermen of Misaki often bring in magnificent specimens 

 during the winter months. They are brought up clinging to the 

 fishing-line. Specimens of Hyalonema in museums of Europe and 

 America are in reality mostly from Misaki, although they are marked 

 as from Enoshima where they are bought and sold. Not less interest- 

 ing than Hyalonema, although not as beautiful, is ïetilla Japonica, 

 Lampe (Arch. f. Naturgesch. 52 Jahrg. I Band I Heft). This is found 

 in great abundance in the harbor of Misaki during summer months. 

 Of the Coelenterata, hydroid colonies are not very numerous, although 

 we found one species of Aglaophenia in great abundance in December. 

 Hydro-medusœ, Acalephœ, and Sea-anemones are fairly numerous. 

 Corals are found living, as also Yeretillum and other Pennatulids. 

 Of the Echinoderms, there are several species of sea-urchins, star- 

 fishes, ophiurans and holothurians, some species being found in 

 great number. A Comatula is also found. A magnificent Pen- 

 tacrinus two or three feet long is brought up in the same manner 

 as Hyalonema. The Mollusca are exceptionally abundant. Tide 

 pools &c. may be said to be alive with them in the spring, and their 

 egg-masses form conspicuous objects at the same season of the year. 

 Some of the more noticeable molluscs are Chiton, Haliotis, Aplysia,
