Hi, Conch-Lers!
I am now fairly clear about the distinction between N. nodosus and N. fragosus. Now, arthriticus is given as the species name for the knobless Lion's Paw. But a number of things are not clear to me: (1) must the shell be completely knobless? (2) what is the range of this spcies; does the range overlap the ranges of nodosus and fragosus; (3) Are there any other distinguishing characteristics, other than the absense of
knobs?
Thanks ahead of time,
Linda
