DESCRIPTIONS OF NEW SPECIES OF MARINE PELECYPODA 

 FROM THE PHILIPPINE ISLANDS, 



By H. B. PRESTON. 



The Mollusca described in the présent paper formed part of the 

 collection of Mr. G. H. Brown, for many years a résident in Manila. 

 A great part of the collection was made up from material dredged 

 in a few fathoms off that port and included several forms which 

 appear to be new to science. 



Tellina manilse, nov. spec. 



Shell oval, inequilateral, flexuous, flattened, rather thin, glossy, 



pink, very finely rayed with white, margins 

 flesh coloured; sculptured with fine concentric 

 lines of growth ; posterior side rather produced, 

 angular; anterior side elongate, oblong, round- 

 ed; umboes small. 



Length, 30 millimètres; ait., 1 95 milli- 

 mètres.

 tric lines of growth rather finer.
