132 OCTNEBRA. 



specimen with coarser sculpture. This form is found abundantly 

 at San Miguel and Santa Rosa Islands off the southern coast of 

 California. Mr. Stearns furnishes me with this figure, (fig. 494).

 varices eight in number, compressed, short, laciniately foliated ;

California. 



Not figured. I can only guess at the relationship of this species 

 and prefer simply to record it, and await the publication of an 

 authentic illustration. 



M. BRAZIERI, Angas. PI. 30, lig. 2N<). 



Shell ovate, ventricose, shouldered ; with five varices, crossed 

 by five strong ribs, some of which are double ; squamous, the

 brownish-purple on the columella and within the aperture.

Yellowish or whitish, varices eight or nine, not much elevated ; 

 canal short, open. Length, *3 inch. 



Isles of St. Paul and Amsterdam, Ind. 0. 



I have ventured to unite with this species the same author's 

 M. Hermani, (fig. 483), which appears to be founded on speci- 

 mens in less perfect condition. The species does not appear to 

 possess any well marked characteristics. 



M. TRITONIDEA, Velain. PI. 39, fig. 4tfi. 



Length, 4 to 5 mill. 



Me of St. Paul, Ind. 0. 



Described as a Troplio-n, but its characters do not correspond 

 well with that o-enus.
