Interchangeable taxa

L'espèce en question offre une certaine analogie avec le Trophon clathratus ; mais il est bien plus grand, plus allongé; son ouverture est moins évasée et blanche à l’intérieur, tandis qu'elle est brune chez cette espèce. Il ne peut pas non plus être identifié avec le T. gunneri, qui est constamment plus petit, possède des tours plus étages et des varices anguleuses vers leur partie supérieure.

T. dabneyi can be recognized from its multispiral, brownish larval shell which indicates planktotrophic larval development. It is the only species, in the area studied, with such larvae. The protoconch, however, is frequently corroded in adult specimens and the species becomes difficult to distinguish from T. echinatus (the cossmanni "form"). Distinctive characters then, are the more blunt spire, less distinct spiral sculpture and less shouldered axial lamellae in T. dabneyi.

Distribution
