Mollusks. 8339 



laughter of the women hauling at the rope, and the noise and splashing 

 of the men in the water, mingle with the loud cawing of the rooks in 

 the great fig trees, and produce an impression on the mind novel and 

 pleasing. As the seine comes slowly in, besides goodly fish of the 

 larger sort, we notice cow-fishes and sea-scorpions, squids, cuttles, 

 file-fishes and long-clawed flat-legged swimming crabs. Crawling on 

 the rocks between tide-marks, where the boulders are covered with 

 soft green Fuci, or hiding in the fissures and furrows, are numbers of 

 Perionia Tongana, Quoy and Gaimard, looking like shell-less Chitons, 

 but which are veritable Pulmonifers living in the sea. 



Not far from Tatiyama is a snug little harbour called Tago, in which 

 are numerous little caves, where one may escape from the prying in- 

 quisitiveness of the people and collect in peace. In all these small 

 bays, sandstone rocks, clothed with stunted oaks and dwarf firs, rise 

 abruptly from the shingle of the beach, and a few miles inland 

 are green mountains which tower up all around. Against the water- 

 worn rocks on the beach are loose rounded stones heaped up by the 

 efforts of the ever-restless tide. The yellow flowers of Hemerocallis, 

 the red-spotted turbans of the tiger-lily, a trailing Clematis and a pretty 

 blue Scilla grow on the shingly soil, while Pitcairnia straminea, Lyco- 

 podium lineare, Pteris cretica and Dendrolium fill up the fissures of 

 the cliffs. Above high-water mark, but exposed to the saline influence 

 of the tides, adhering to the under surface of the stones, crawling in 

 damp shady corners, or nestling in the weed-grown crannies, are thou- 

 sands of Realise, small cyclostomatous snails. Not only Realise, how- 

 ever, for Lygiae run out in great excitement, Armidillidia roll themselves 

 up in balls, crickets hop nimbly aside, and sinuous Geophili hastily 

 seek the shelter of surrounding stones. The animal of this species of 

 Realia is light black ; the tentacles are short, cylindrical and obtuse 

 at the tips ; the eyes, large and black, are placed on tubercles connate 

 with the bases of the tentacles ; the muzzle is broad, annular, depressed 

 and rounded in front ; the foot is short, narrowed in the middle and 

 obtuse at both ends, and carries the operculum close to the body under 

 the shell. The creature crawls quickly, exactly like Assiminia, placing 

 the muzzle in advance, moving forward the fore part of the body and 

 rapidly bringing up the hind part. The operculum is not visible when 

 the animal is on the march. Thus we see that Realia affects the same 

 localities, and has all the habits and mode of progression of Assiminia. 

 Both genera live within the influence of the tides above high-water 

 line, and when on the coast always within reach of the spray. The 

 only difference between the two is in the position of the eyes, which
