Dendronotus arhorescens. 



A. Shanny Tank : — 



Dendronotus 1. — Seized at once by the large shanny and 

 kept in mouth, half the niidibranch projecting. 

 This shanny was pursued by others, one of which 

 caught the projecting end of the prey, and in the 

 ensuing struggle tore half the body off and eat 

 it. The large shanny at once retreated with the 

 remainder to the back of the tank ; came out 

 shortly afterwards with the Dendronotus still in 

 mouth, and was again pursued and retreated to 

 the back, appearing again soon without the nudi- 

 branch. 



C. Table Tank :— 



Dendronotus 1. — Pounced upon at once by three bullheads 

 which made rapid dabs at it successively, until 

 one secured it and carried it off to a quiet place 

 where he seized it in his mouth and rejected it 

 nine times in succession, each time taking it 

 half into the mouth and keeping it there for 

 some seconds, then spitting it out and at once 

 pouncing upon it again. Finally the now some- 

 what mangled remains of the Dendronotus were 

 taken out and put into tank A, where one of 

 the shannies at once seized and swallowed it. 

 The Dendronotus was large. It was larger than 

 the head of the Cottus, and caused the mouth 

 cavity to bulge out greatly when half taken in. 

 The general impression was that tlie Cottus found 

 the Dendronotus desirable food but an uncom- 

 fortably large mouthful and was trying to worry 

 it to pieces.
