—(A) Selected species of the subgenus Turriconus. (i) Conus andremenezi, (ii) Conus praecellens, (iii) Conus excelsus, a famous rarity known from only a few specimens for many centuries, and still a desirable shell collectors treasure, (iv) Conus miniexcelsus, and (v) Conus acutangulus. The shell of C. andremenezi can be distinguished from that of similar closely related species by a generally broader shape, characteristic purplish-brown maculations, undulating spiral ribs, widely spaced ribs on the spire, and a distinct protoconch. (B) Aquarium images of living C. andremenezi (top) and C. praecellens (bottom). Note color difference in siphon (blue arrows) and foot (red arrows). Conus andremenezi has a darker foot but whiter siphon than C. praecellens.
