Chilonopsis nonpareil (Perry)

Large Saint Helena Awl Snail (Chilonopsis nonpareil)  

The Large Saint Helena Awl Snail is the largest member of its genus, some shells reached sizes of up to 4,7 cm.  


See Thomas Vernon Wollaston in 1878 (Testacea Atlantica).:  

The B. auris-vulpina, which has been brought from St. Helena by almost every naturalist who has visited the island during the last fifty years, appears to be quite extinct; though the comparatively perfect preservation of occasional examples, in which the outher cuticle is hardly destroyed and even the colour is partially traceable, would perhaps imply that it must have lingered on to a somewhat recent period.” [1]
