inpinge upon it, sharp-edged, thickened within and there lirate; 

 anterior canal somewhat reflexed. 



This species differs from all species of this genus heretofore 

 described, by its extremely high spire, the revolving line below 

 the carina of the spiral whorls, and in the structure of the lowest 

 carina on the body whorl, i. e., it is narrow, sharply defined 

 and spine bearing, while in all other known species it is broad, 

 smooth and indefinite. Were the specimen figured not flattened 

 by pressure it would appear much more slender, or Fusics-M^e.

Levifusiis dalei n. sp., PL 9, fig. 12. 



Specific characterization. — Size and general form as indicated 

 by the figure; whorls about 6; i and 2 smooth, 3, 4, 5 with a den- 

 ticulate carina below the middle of each whorl; body whorl with 

 a humeral carina bearing about 20 compressed denticulations, 

 above with lines of growth prominent and showing a broad yet 

 well defined retral sinus, below with lines of growth fine but 

 visible and distinct; spiral strise above the carina extremely fine 

 and even, below the same, stronger and alternating in size; pillar 

 long and straight with a thin coating; labrum smooth within. 



Fragments of larger specimens show that the carinal spines 

 become long yet very much compressed vertically, with age; the 

 spiral lines below the carina become very pronounced. 



The general form of older specimens approaches Fusus quin- 

 quespimcs Dall, though of course there are more than five spines.

FULGUR. 

 Fulgurf dallianum n. sp. , PI. 9, fig. 13. 



Specific characterization. — Size and general form as indicated 

 by the figure; spire low, whorls about 5, the humeral angle of 

 each corresponding to the suture or nearly so, faintly tubercular; 

 body whorl bicarinate, the upper carination ornamented with 

 vertically compressed, not prominent, tubercles, the lower carina- 

 tion less prominent and not ornamented; inner lip somewhat 

 calloused and covering the inner margin of the columella and 

 the inner lower portion of the adjacent whorl; lines of growth 

 when leaving the suture not directed radially outwards but bent
