8. LEPRALIA ANSATA. 



Hab. On slaty rocks, Cornwall, Peach. 



Cells ovato-globose, slightly punctured; aperture circu- 

 lar, with a sinus above. " On each side of the aperture a 

 hollow auricle projects forwards ; and, viewed in front, these

 found in the east and west of Scotland, and in the north

9. LEPRALIA OVALIS, A. H. Hassatt. 



Hab. On dead bivalve shells. Kingstown and Burnham, 

 Hassall ; coast of Ireland, Mr. W. Thompson ; Devonshire, 

 Mr. Peach and Dr. Greville. 



The cells are oval and distinct ; the aperture is circular, 

 with a knob above, and two spines on the under lip. 



10. LEPRALIA LINEARIS, A. H. Hassall. 



Hab. On stories, east of Kingstown Harbour, and at the 

 Giant's Causeway, Hassall; Orkney, Dr. Greville.
