IIG Dr. J. C. Melvill and Mr. R. Standen on 



Rapid Point, also at low tide. 



The specimens from the former locality more assimilate 

 the type. It is impossible to separate falklandiana us a 

 genuine species.

Rapid Pointj at low water ; also Roy Cove. ^Several 

 examples. 



In a previous paper (Journ. of Concli. x. p. 45, 1901) we 

 mentioned this species under the name of Fissurellidea 

 liianiula, Lam. {non Reeve). This was seven years before 

 it was properly differentiated and named by Dr. Strebel. It 

 would appear to be the only one of its kindred inhabiting- 

 this region.
