The above species were founded on very immature shells, and, in 

 a large series, merge into one another. The type of acuminata 

 measures 4'5 x 2 mm., while the largest examples that I have 

 examined from Port Elizabeth are 20x4 and 19'5x5 mm. respec- 

 tively ; there seems no doubt, however, that these are the adult of 

 Morelet's species. They are closely allied to the variable European 

 Phytia myosotis (Draparuaud).
