54 COLUMBARIUM. 



not so ornate ; and the protoconch differs, as already described. 

 It is closely allied to C. pagodoides, "Watson, obtained by the 

 "Challenger" expedition off Sydney in 410 fathoms of water; 

 from which it differs in having a much smaller protoconch and 

 a non-spinose anterior canal. 



Fusus craspedotus, Tate,^ is stated by its author to belong to the 

 same group as his, F. foliaceus (= Columharium foliaceum). Several 

 examples of that species are in the Museum collection ; and the 

 present writer, from a careful examination of that and other 

 material, believes that the differences in the respective proto- 

 coachs, and the general phenomena of the aperture and ornament, 

 are sufficient to warrant generic separation. At the same time 

 it must be remembered that as the status of this genus largely 

 depends on the character of the radula, and as that part of the 

 animal is not found in fossil specimens, the classification of fossil 

 species which conchologically resemble the recent forms, must 

 always remain doubtful.

Similar to C. acanthostephes, but with shorter spire ; the posterior 

 slope of the whorls has no spiral ornament ; angular ridge spinose, 

 the spines being irregularly developed in regard to size ; in front 

 of this, and coinciding with the posterior angle of the aperture, is 

 a slender, crenulated, spiral carina, and minor spiral threads are 

 developed anteriorly; aperture subquadrate, contracted in front; 

 outer margin dentate ; anterior canal long and spinose.
