58 SHARKS AND SHELLS. 



open country^ and beings very wary^ it is only by 

 stratag'em or accident that they can be approached 

 within g'unshot. No hmd snakes were seen^ but 

 sea snakes seem to be frequent in the harbour. 

 Sharks of enormous size appeared to be common 5 

 one day we caught two^ and while the iirst taken 

 was hang*ing- under the ship's stern, others made 

 repeated attacks upon it^ raising- their heads par- 

 tially out of the water^ and tearing* off long- strips 

 of the flesh before the creature was dead. Another 

 swam off apparently as active as ever^ althoug-h a 

 musket ball had been fired through its head. On 

 several occasions a party was sent to haul the seine 

 upon a neighbouring mud flat covered at high 

 water, and generally made good captures, especially 

 of mullet and bream (Chrysoplirys) ; in addition, 

 many other more curious fishes were caught, and 

 several rare and new Crustacea — Sqiiilla^ Lupea 

 Thalamita, and a new genus allied to GonoplaXj 

 which will be found described in the Appendix. 

 Of landshells, only two kinds, a Helix and a 

 Succinea, were found upon Facing Island. Of 

 marine species, 41 were added to the collection ; 

 the most important in a non-zoological point of 

 view is a kind of rock ovster of delicious flavour 

 and large size.
