Observations. 



rocks, and I presume that they must have lived in the 

 roots of fuci, in which situation they are sometimes met 

 with on our coast. 



Common at Capellbacken. 



I found one individual, which seems not distinguishable, 

 in size or shape, either from the fossil or recent T. bal- 

 tica of the neighbourhood of Stockholm. 



Shell rather convex, transversely elliptical, thin; its sur- 

 face strongly furrowed ; furrows rounded, about sixteen. 

 Lunette deep, elliptical. Lateral tooth slender, elon- 

 gated, more transverse than the recent Astarte Garensis, 

 and with somewhat fewer furrows, but perhaps a variety 

 of the same? 



Shell convex, transversely elongated, but less so than 

 the former ; both the anterior and posterior margins more 

 rounded than in the preceding ; rather thin ; its surface 

 strongly furrowed ; furrows deep, rounded, about sixteen. 

 Lunette deep, lanceolate, elongated. The lateral tooth 

 slender. Perhaps, like the former, a variety of A. Ga- 

 rensis, to which it approaches much nearer. 



Shell compressed, suborbicular, slightly truncated on 

 the posterior margin ; thin ; its surface rugose, marked 

 with many transverse furrows when young. Lunette 

 deep, lanceolate, short, pointed. Lateral tooth small, 

 short. Fulcrum long. 



In great abundance, and preserving a portion of its 

 colour ; about two inches in length. 



From Kured. 



In great abundance, often preserving its colour, and 

 covered with Balani. 



A single perforated valve is all that I found of this 

 genus. 



This Patella is referable to the genus Lottia, Gray, 

 (Philosophical Transactions, 1834.).
