 GEN. XVI. 



ANOMIA. 



Animal not reducible to any liitherlo found in 

 a mollufcous ftate. 



It appears to be different in fome fpecies oi Anomia, as 

 may be feen by comparing that of the Cepa figured by 

 Murray in his FundamentaTeJlaceologice , t, 2. f. 23. 

 and the tridentata, fo called by Forskal, in his Iconcs 

 Animalium, t. 6. 40. 



The animal of the A. patelliformis feems to be different 

 from either of thefe, by the defcription Linn.<«:us has 

 given of it. 



SHELL, bivalve, inequivalve ; one valve ufually flat, 

 the other convex : in feveral fpecies the flat valve is per- 

 forated near the hinge, through which the animal is im- 

 moveably fixed by a teftaceous plug to fome other body. 



Hinge toothlefs : a tranfverfe, linear prominence on the 

 flat valve, connefted under the beak of the oppofite valve 

 by a flrong cartilage.
