gated and insensibly passing into a rather wide and short canal; 

 siphonal fasciole rather marked, though the siphon is not re- 

 curved; pillar smooth, nearly straight with little callus; the body 

 with no subsutural callus; the outer lip slightly flaring, hardly 

 thickened; Ion. of shell 26, of aperture 15.5, lat. 13 mm. San 

 Pedro, Cal., in rather deep water, E. W. Roper; in whose honor 

 the shell is named. This is a singular species, recalling Ocinebra 

 or Muricidia by its surface sculpture and the constricted and ap- 

 pressed sutural region of the whorls. I have not been able to 

 find any species with similar characters in the monographs or 

 in the national collection. It is probable that it should be sep- 

 arated sectionally from the group typified by F. colus, and it can- 

 not be associated with Sipho or Chrysodomus, so it may be re- 

 garded as typifying a new section, Roperia." — Dall, Nautilus,
