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; lon. of shell 26, of aperture 15.5, lat. 13 mm. San 
Pedro, Cal., in rather deep water, BE. 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,
