Levifusus trabeatoides nov. sp. PI. 6, fig. '12, a. 

 Fusus trabeatus Heilp. (not Con.), Proc. Ac. Nat. Sci. Phila., 1890, p. 395. 



Specific characterization. General form a"s figured ; whorls 8 or 9; 

 1, 2, 3 smooth and polished, 4 sub-biangulate, 5, 6 with one spiral 

 line just below the suture and two or three more near the base of 

 each whorl where they are crossed by sharp, fine, costee, 7 evenly 

 striate spirally showing more or less distinct costse and curving lines 

 of growth; body whorl evenly striate, bicarinate, with faint indica- 

 tions of tubercles on each carina, lines of growth with a retral curve 

 above the upper carina resembling those of Surcula; labrum strongly 

 Btriate within. 



Below the two prominent carinse there is a third faint one. Large 

 old specimens sometimes show on the body whorl one very strong 

 carina above, while the two lower are rudimentary. Fragments 

 have been obtained which would indicate a total length of an entire 

 specimen of at least three inches. 



The generic name Levifusus, as far as the writer is aware, has 

 never been characterized ; yet since Conrad has referred to it the
