76 THE LIFE OF THE MOLLUSCA 



confinement through two summers, became torpid in 

 October, 1851, and was found to be dead in Ma}', 

 1852. This specimen (Plate XIIL, Fig. 34) was 

 figured by Dr. S. P. Woodward in his "-Manual of 

 the Mollusca." The Rev. A. H. Cooke collected 

 examples of this species in Egypt in 1904, and kept 

 them in a tin box without food. In January, 1912, 

 ten individuals were still alive, but only three sur- 

 vived by the following March, although food had 

 been supplied to them. 



There is a record in the Philosophical Transac- 

 tions for 1774 of some Snails that had lain by in a 

 cabinet for more than fifteen years resuscitating on 

 being placed in water ; but, despite the detailed state- 

 ment and assertion that no error was possible, the 

 narrative does not seem credible. 



Such dainty morsels as molluscs are naturally 

 relentlessly pursued and devoured. Leaving man 

 out of the question, many animals from the Whale 

 to the Mouse prey on them. 



A Monkey (Macacus cynomolgus) has been seen to 

 feed on Oysters, the shells of which he broke open 

 with a stone. The Right Whale devours enormous 

 quantities of Pteropoda with other pelagic creatures ; 

 the Cachalot, Grampus, and other Cetacea, devour 

 Cuttlefish. The walrus digs Bivalves out of the 

 silt on the sea-floor with his tusks, and eats them.
