150 THE ZOOLOGIST. 



A little later, though at what time I am not certain, Star- 

 fish A also quitted the Pipe-fish, which I removed from the water 

 at about 11 a.m. The eyes had disappeared, together with the 

 contents of the abdomen and the skin of that part of the body 

 of the Pipe-fish which had been within the stomach of the 

 Starfish. 



Neither of the two living specimens of Siphonostoma typhle 

 has been touched, nor have two of the Pipe-fishes of the species 

 known as Nerophis ophidion, which have lived in the aquarium 

 for several weeks, although these fishes lie for the most part 

 quite still at the bottom of the tank, and make little or no 

 endeavour to move away when the Starfishes walk over them. 

 The latter, however, have killed and eaten, within a few months, 

 about half a dozen healthy examples of the Common Brittlestar 

 (Ophiothrix fragilis) , white fragments of whose skeletons still lie 

 strewn over the sand at the bottom of the aquarium.
