NUDIBRANCHIATA OF THE L.M.B.C. DISTRICT. 157 
going about for some time afterwards (5 p.m.) 
with the mouth held open, but was all right again 
next morning. 
C. Table Tank :— 
Kolis 2.—(Galvina picta)—Touched or tried and rejected 
at once by cod, bullhead, and weever. ‘The cod 
came very near it or touched it with its snout 
several times afterwards, but never took it into 
the mouth. 
Holis is undoubtedly distasteful. The cnida on the tips 
of the cerata probably sting the lips, &c., of the fish. 
Asit had occurred to us that the natural conditions would 
be more nearly reproduced if the nudibranchs were not 
dropped into the tank, on the following day, February 
22nd, a few specimens of Ancula were placed upon pieces 
of stone and lowered 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 crawling over various parts of the tanks for several 
days untouched by the fish (shannies and flat fish). Woods 
(the Aquarium attendant) tells us that the fish sometimes 
went close to the Ancula and looked at them but never 
attempted to touch them. The nudibranchs were last 
seen about a week 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 hable to do when kept in captivity. 
IT. March 22nd, 1890. [We brought to the Aquarium 
specimens of Dendronotus, Kolis, and Doris, which we 
had collected at Hilbre Island on the previous after- 
noon. Mr. Moore, Mr. Chard, assistant, and Woods 
were present—Professor Herdman taking notes. |
