The above occurs at the Hawaiian Islands, of a perfectly glo- 

 bular shape. It will probably prove to be a variety of oryza, 

 Lam.

We hold the above to be distinct from oryza, with which Mr- 

 Reeve has connected it. It occurs at several localities in Poly- 

 nesia, and always retains the elongate form, as represented by 

 Mr. Keiner. 



Cerithium maculosum, Migh. 



1845. Proc. Bost. Soc, p. 22. 



The above name has been applied by Mr. Kiener to a species 

 inhabiting the west coast of America, which was subsequently 

 described by Mr. Sowerby as nebulosum, which name it should 

 retain, to distinguish it from the above Polynesian species.

The sculpture of this species varies but little ; in color and 

 size, however, it passes through many variations.
