Approaches in form C. orion and classiarius, both of which are 
more elongated; its proportions are, perhaps, more like C. fulgu- 
rans. Its coloration is like some varieties of Cedo nulli, and C. 
archon, or like the darker varieties of C. portoricanus. ltis proba- 
bly the species named by Menke, in his Catalogue of Mazatlan

Shell quite small, conic, very slightly swollen posteriorly; sur- 
face smooth, the anterior half having about eight circles of beads so 
spaced as to form squares; spire nearly level, composed of eight 
coronate whorls divided by a spiral groove; color white, with &

Allied to C. sponsalis, ipsu in coloring, but is smaller, with- 
out convex outline, more elongated, spire much less. elevated. 
Nearly the same remarks apply to C. nanus, in which there is less 
resemblance as to color. Its proportions are more like C. speciosis- 
simus.
