ANOMIA. 



Animal an emarginate ciliate strap-shaped bo- 

 dy, with bristles or fringe affixed to the uppef 

 valve. Arms two, linear, longer than the body, 

 connivent, projecting, alternate on the valve, 

 and ciliated each side \ the fringe affixed to each 

 valve. Shell bivalve, inequivalve ; one of the 

 valves flattish, the other gibbous at the base, 

 with a produced beak, generally curved over 

 the hinge ; one of the valves often perforated 

 near the base. Hinge w T ith a linear prominent 

 cicatrix, and a lateral tooth placed within ; but 

 in the flat valve, on the very margin, two bony 

 rays, for the base of the animal. 



1* ephippium. P. D. M. Not uncommon, adhering to 



oysters, stones, &c. Frith 

 of Forth. The variety 

 named by Dr Pulteney ro- 

 sea 9 I have never met with 

 on the Scotch coast. These 

 shells partake of the form 

 on which they happen to 

 be placed, and a beautiful 

 ribbed variety may be 

 found from their having 

 been affixed to Pecten 

 maximus, or shells of thai 

 genus.
