This shell, having a regular oblique growth, appears to

 garded of importance in determining species. 



Species 23. (Fig. a, b, Mus. Cuming.) 

 Anomia nobilis. Anom. tesld late ovatd, plana, solidi- 

 ■iisculd, subirregnlari, radiatim costatd, costis subdis-

Eab. Singapore (on dead shells, in coarse sand and gravel 

 at a depth of about ten fathoms) ; Cuming. 

 The upper valve of this species is curiously distinguished
