4. — Seized and rapidly rejected by five fish in 



succession. 

 5. — Seized and rapidly rejected by four fish in 



succession. 



p. Flat Fish Tank :— 

 Ancula 1. — Seized and rejected by a young cod and six 

 plaice in rapid succession. 

 2. — Seized and rejected by seven plaice in rapid 



succession and left lying on sand. 

 3. — Seized and rejected by four plaice in rapid 

 succession and left lying on sand. 



The fish were then tried with some cockles, which, 

 when thrown in, were eagerly pounced upon and eaten. 

 Then four specimens of Ancula were thrown in together 

 and were tried and rejected by two young cod and three 

 plaice. 



C. Table Tank:— 



Ancula 1. — Touched by a young cod but not taken, then 

 tried and rejected by goldsinny. 



2. — Touched and rejected several times by cod. 



3. — Touched and rejected by first cod, bolted sud- 

 denly by second. 



The shannies at once take an object into the mouth

 appear. The shanny seems to test the edibility inside its 

 mouth, the cod outside. 



Some crabs {Ilijas araneus) in two small tanks were 

 then tried with specimens of Ancula with the following 

 results :—
