Discussion. The new species is rather close to 
Herpetopoma eboreum Vilvens & Héros, 2003 (Figs 
20-21) from New Caledonia, but this slightly greater 
species lacks always an umbilicus, has a slightly 
cyrtoconoidal (not strictly conical) shape with only 
weakly convex to almost Hat whorls, more close 
together spiral cords on the last whorls and up to 7 
spiral cords on the base with interspace between cords 
as broad as cords. 
Herpetopoma poichilum n. sp. is rather close to H. 
elevata Jansen, 1994 from Queensland, but this 
similar in size species has more convex whorls, four 
(not five), uneven in strength spiral cords on the last 
whorl with pointed (not rounded) nodules, four (not 
five) narrow spiral cords on the base. 
Etymology. Embroidered (Greek ^oix^oQ - with 
reference to the reticulate sculpture of the whorls.

Comments. This single specimen is too eroded seems 
ditfeient ot every chilodontid known species, but its 
poor State could not lead to reliable description and 
comparison.
