238 APPENDIX, VOL. XXVI. 



Island, writes that he is "disposed to believe it distinct from 

 ccenopictus, as the Bombay specimens are all alike. In pick- 

 ing over some shell sand from Karachi beach, however, I found 

 an apparently mixed race, varying much in size." These 

 may have been washed together from several colonies.

OP UNCERTAIN POSITION. 

 PUPA LAMARCKH Audouin. PL 24, figs. 8, 9, 10. 



Known only by Savigny's figures, here reproduced photo- 

 graphically, which represent a short shell with expanded lip 

 and a carina on the last whorl. The latter looks like the re- 

 mains of a whorl which has been broken away, the animal 

 afterward forming a lip at the limit of the breach. I have 

 seen such specimens; and I suspect that it is a pathologic 

 Pupilla. The length as indicated on the plate is 2.8 mm. Pre- 

 sumably from Egypt.
