 p. 4, t. 1, f. 9. CA. siculoides CPR., MS. 



This species has been referred by Smith to C. siculus Gray. The 

 locality requires confirmation, as it rests solely upon Cumingian 

 specimens. Hutton (Man. >.'. 7. Moll.) reprints Reeve's diagnosis 

 without comment. 



Carpenter's notes on Reeve's type are as follows ; Central areas 

 having about 20 furrows on each side, not deep, continuing until 

 they are rubbed off in the middle; lateral areas having 4-8 divari- 

 cating riblets, much worn, broken up by the concentric ruga of 

 growth; crenate at the sutures; end valves with about 30 riblets. 

 Mucro in front of the middle, posterior slope concave. Interior
