220 THE YOUNG NATURALIST. [November 



took a splendid series of Idotea tricuspidata, a crustacean variable both 

 in markings, colour and outline. It receives its specific name from 

 the last segment being terminated by three points, though specimens 

 bearing but two processes are very much commoner. The colour 

 varied from green, without markings, to a ground hue of reddish 

 brown, bordered on the margings with an irregular yellow line. 

 A very common Amphipod was Podocevis pulchellus, a very quaint 

 looking and formidable creature. 



We also spent an hour one evening in examining the stomachs of 

 the dead fish thrown up by the tide, and a very heterogeneous mixture 

 found we therein. But what struck us as more especially interesting 

 was the vast quantity of Nematodes in the digestive canals of Cod 

 Fish, Morrhua vulgaris. A single stomach must have contained one 

 or two hundred. Numbers of Dog Fish, Scyllium canicula, lay among 

 the refuse at high water mark, and in the U-shaped stomach of one in- 

 dividual we found the undigested viscera of a Cod, the latter, upon 

 being opened, revealing the presence of a long, white tape worm. It 

 was impossible to measure it as it fell to pieces during removal, but 

 there must have been a good clothes yard or more. 



Monday morning, early, saw us working the shore on the south 

 side of the Bay, a portion of this prolific locality so frequently referred 

 to already that any further description will be unnecessary. Our cap- 

 tures were chiefly made under stones, often of considerable size, and 

 requiring the united exertions of two individuals to upraise, and com- 

 prise large numbers of Sycandra ciliata, Ophiothrix pentaphy Ilium and 

 Galathea squamifera. The latter, the largest of the squat Lobsters' 

 attaining a length of 4 cm., is perhaps the prettiest of the group. 

 The colour is deep olive green, the fused cephalothoracic segments 

 being most distinctly visible. The fusion of the segments is so 

 effectually accomplished in the Crayfish, that no indication remains 

 either dorsally or laterally ; but in G. squamifera, the five segments 

 composing the head, and the eight thoracic divisions are plainly dis- 

 tinguishable. Another common Crustacean is Porcellana longicomis, 

 the allied species, P. platycheles being apparently absent. 



Numbers of small fish find a congenial shelter beneath the stones, 

 the most abundant being the Spotted Gunnel, Blennius gunnellus. The 

 ground hue of this pretty fish is sandy yellow T , varied with black spots, 

 and many specimens reach a foot in length. It is very difficult to
