The Patella inhabit all seas, and are most abundant in individuals. 

 Some of the finest are from the shores of the Cape Colony. We have 

 three species in Britain, P. vulgata,* athletica, and pellucida ; the first 

 two of these are rock-dwelling species, the last inhabits seaweeds and is 

 the type of a separate genus, Patina.

* " The common Limpet is universally distributed around our coasts, living on the surface of 

 rocks and stones between tide-marks. Although capable of moving about with facility, when 

 well-grown it appears to become lazy and sedentary, often living in crevices, where, having once 

 lodged, it remains till it becomes too large to come out. "When it moves about, it makes upon the 

 rock a curious fucoid-like track of some breadtb, probably caused by the edges of the shell. On 

 calcareous rocks, and especially upon chalk, it frequently, as it were, excavates a cavity for it- 

 self, apparently by the action of the carbonic acid set free during respiration, since the marks 

 of the action of the ciliary currents from the gills are distinctly visible. This animal is some- 

 times used for food, though much too leathery to become a delicacy." — Forbes and ' Hanley ; Bril.
