TKIANGLE - SHELL. 51 



found on the beach, thrown up by the waves. 



The Kelly-shell, Kellia Zaperousii, Desh., 

 shown in Fig. 6, PI. XIII, belongs to a little 

 moll n sk which shelters itself in clefts and holes, 

 as the shell is thin and delicate. It has been 

 mistaken for a borer, and it frequently lives in 

 the empty holes of boring mollusks. The shell 

 is smooth, oval, and light brown in color. It 

 has one lateral and two cardinal hinge teeth, 

 with a ligament between them. 



A pretty little shell, not half an inch long, 

 may sometimes be found fastened to the rocks 

 in concealed places. An enlarged figure of it is 

 shown in Fig. 7, PI. XIII ; it is called La- 

 zaria subquadrata, Cpr. It is strong, full, and 

 marked by fifteen strong, rounded ribs, radiating 

 from one angle ot the four-sided shell. Its color 

 is white, variously marked with brown spots. It 

 is used in ornamenting shell frames. 



CJdone simillima, Sby., is found in the south- 

 ern part of the State. Its length is two inches, 

 and its breadth is nearly the same. The valves 

 are very strong and thick, finely sculptured in 

 two directions ; the radial lines are rounded, and 

 the concentric ones are thin and sharp. Heart- 

 shaped lunule, conspicuous ; ligament, external, 

 at the base of a broad depression ; cardinal teeth, 

 strong, three in number ; pallial lines, entire ; 

 color, brownish white, deeply stained inside with 

 purple ; edge, slightly crenulated.
