988 ON SOME RECENT SHELLS FOUND ON THE MACLAY-COAST, 



LIST OF SOME RECENT SHELLS FOUND IN LAYERS 

 OF CLAY ON THF MACLAY-COAST, NEW GUINEA. 



By J. Brazier, C.M.Z.S., &c. 



About two months ago Baron Maclay brought ni3 a small box of 

 shells for determination, which he had obtained on the North-east 

 Coast of New Guinea in the year 1877. The whole of the species 

 seem to have been thrown from the bed of the Ocean by some 

 volcanic or submarine agency. Having gone carefully through 

 them, I find that they are species common to the Philippine 

 Islands, China Sea and Torres Straits. Some of them are very much 

 sea worn and past identification, others again are represented only 

 by a single example and odd valves. A list of them is here 

 given : —
