ANOMIA. 291 



Shell about an inch and a half long, and thirteen lines broad ; 

 of a greyish white colour, and the convex valve has bifid 

 longitudinal striae, which are furnished with minute brittle 

 scales. Bruguiere, though he has retained the name, says 

 this is perfectly distinct from the Anomia pectinata of Lin- 

 naeus, which is entirely a fossil species. 



cylindrica. 13. Shell oblong, sub-cylindrical, 

 coarse, and slightly striated ; upper valve 

 convex, perforated, and the umbo incurved.

Inhabits the coasts of Norway, adhering to the spines of Echini. 

 Schroeter. Great Britain on Sertulariae. Montagu. 



Shell about half an inch long, and the length rather exceeds 

 the breadth ; the upper valve is considerably convex, and 

 contracts at the umbo into a lengthened beak which is in- 

 curvated over the other valve ; the lower valve is very con- 

 vex and gibbous, and conforms to the shape of the substance 

 it adheres to ; the colour is white. 



scobinata. 14. Shell roundish, striated longitudi- 

 nally, and the inside rough; umbo perfor- 

 ated.

The shell figured by Chemnitz for this species, is about half 

 an inch long, and the breadth rather exceeds the length ; the 

 colour is pale reddish brown ; the description given by Lin- 

 naeus is very short and unsatisfactory, and Gualter, t. 96. f. 

 A, to which he has referred, is more like Anomia truncata. 



aurita. 15. Shell ob-ovate, striated, and slightly 

 eared ; umbo perforated.

Linnaeus has given only the above very short description, and 

 has referred to Gualter, t. 96. f. B. which Born and Chem- 

 nitz have quoted for A. Caput-serpentis.
