Novapex 12(1-2): 1-38, 10 mars 2011 
bordering the siphonal canal, where it is strengthened 
and keel-like with a prominent, elevated internai 
lamina (sensu Dolin & Lozouet, 2004), separated from 
the columellar teeth by a deep groove; fossula hardly 
developed and poorly delimited from the rest of the 
columella, very steep, bearing ridges which extend to 
the inner edge, ending in a denticle; 20-24 coarse 
labral teeth, outer lip bevelled inwards, with teeth 
extending across the bevelled inner portion and a short 
distance onto the labrum. A suggestion of a fine, 
messy spotted marginal colour pattern is preserved in 
sorne specimen, enhanced under UV light.
