21:0034 Sinum californicum Oldrovd. 
“Shell white, convex, spirally striate above. with epidermis 
of a rusty yellow; a thin columellar callus reflected nearly over the 
umbilicus showing only a faint trace of umbilicus; interior snow- 
white. This has been called Sigaretus debilis Gld., but it is not 
like the specimens from Lower California. It differs from S. con- 
cavum in net being as convex, and the interior being white, and 
the early whorls are much smaller, and from 8. debile in being 
convex and !arger. SS. debile is very flat, the early whorls are 
much smaller and fewer. Length of shell 38 mm., breadth 18 
mm., height 13 mm.’’ 
Type locality:—San Pedro, Cal. Ranges from Monterey, Cal., 
to Todos Santos bay, Baja California. Probably 183 is this specied.
