Many Viilvcs, beiicli ; one live si)eciiuen. Toito (IraiMlc (Mu.s. Nos. 

 125321), 12r);u;()); Aslinntc<' (Mus. No. 12r);i;}5); Frc'c Town (Mns. No. 

 125408). 



Valves only lioni I'oilo (liainle and Vvrc Town. The only live exam- 

 ple of tliis sti'onj^ly {'haiacterized lonn is the Ashantee specimen. Ex- 

 teiiially it resembles a dardita rather than an Ark shell. 



Tiu' Free Town (Sieira Leone) cxanijjies, valves only, are in a .semi- 

 Ibssilized state, the surfaee somewhat (leeonip()se<l. The j^eneral facies 

 is mnch modified and somewhat misleading throuj^h weathering; this 

 action of the elements, however, has exposed the hinge area, which 

 exhil)its the develo[)ment and iinal growth of the hinge teeth. The 

 varions stages may he seen between the npper line of the hinge and 

 the nnder side of the beak or umbo, in close linear grooving. These 

 cansed me at first to think that such valves belonged to some other 

 species.
