NUDIBRANCHIATA OF THE L.M.B.C. DISTEICT. 157 



going about for some time afterwards (5 p.m.) 

 with the month held open, but was all right again 

 next morning. 



C. Table Tank :— 



EoUs 2. — {Galvina iiida) — Touched or tried and rejected 

 at once by cod, bullhead, and w^eever. The cod 

 came very near it or touched it with its snout 

 several times afterwards, but never took it into 

 the mouth. 



Eolis is undoubtedly distasteful. The cnida on the tips 

 of the cerata probably sting the lips, &c., of the fish. 



As it had occurred to us that the natural conditions would 

 be more nearly reproduced if the nudibranchs w-ere not 

 dropped into the tank, on the following day, February 

 22nd, a few specimens of Ancula w^ere placed upon pieces 

 of stone and low^ered cautiously into tanks A and B in 

 such a way as not to attract the attention of the fish. 

 The nudibranchs reached the rockwork safely, and were 

 seen crawiing over various parts of the tanks for several 

 days untouched by the fish (shannies and flat fish) . Woods 

 (the x\quarium attendant) tells us that the fish sometimes 

 went close to the Anc^da and looked at them but never 

 attempted to touch them. The nudibranchs w^ere last 

 seen about a w^eek after being put into the tanks. They 

 then disappeared, but may possibly have retreated into 

 the back part of the tank, or have crawled up out of the 

 water as Ancula is very liable to do when kept in captivity. 



III. March 22nd, 1890. [We brought to the Aquarium 

 specimens of Dendronotus, Eolis, and Doris, w^hich we 

 had collected at Hilbre Island on the previous after- 

 noon. Mr. Moore, Mr. Chard, assistant, and Woods 

 were present — Professor Herdman taking notes.]
