The intended appellation _angulata_ was changed from an erroneous
impression of the identity of the species with the _Turricula plicata_
of Rumphius. "Mucronatis" and "albidus" were emendations. "Bonan. 8.
f. 65" was referred to, as in the 'Systema'.
V. PERTUSA. _V._ fusiformis, labro denticulato, striata punctis
pertusis.
_V. denticulata_ was the name originally proposed for this _Mitre_.
