146 BURMA, ITS PEOPLE AND PRODUCTIONS. 



CritA KtosQuiFonMis, Duclos. 



Rapa papyeacka, Luin. Andamans. 



The liabitat of this shell, which has hccn captured alive by tlie Rev. C. Parish, 

 is very curious. It burrows in the substance of a species of sponjic, which crusts the 

 rocks to a thickness of several inches ; forming a thick leathery coating, which has to 

 be torn in pieces to extract the living shells. Dead shells can he picked up in plenty, 

 but the living shell is only to be found buried in the substance of the sponge, at the 

 Andamans at least, so far as Mr. Parish could judge. The operculum is ovate, poiat«d 

 at one end, and corneous. 



Magilus ANTiQUOKu.^r, Mout. 



This curious little shell lives imbedded in living coral, to keep pace with tlio 

 growth of which, and prevent itself being overlapped and smothered, the lip of the 

 shell is produced into a long tube parri passu with the growth of the surrounding 

 mass ; thereby maintaining access to the free water of the sea. On removal fi-om the 

 inclosing coral, the shell of three or four whorls, the size of a 'periwinkle,' is seen 

 glued, as it were, to the end of an enormously disproportionate tube of a couple of 

 feet or more in length, and solidified throughout, save its mouth, which is occupied 

 by the animal. 



Famihj Olividae. 



Teeth in three series. Tlie siphon recurved. Foot large and usually retlexed 

 over the sides of the shell. Operculum small or wanting. 



HARriN^. 



Operculum none. Shell veutricose, ribbed. These animals are handsomely 

 coloured and variegated, and have the singular power of spontaneously detaching 

 a portion of the foot when molested, resembling in this respect JIuliotidea and Genu. 

 At Mauritius they are caught with lines baited with ilesh (Adams).
