Gray named this species Atlanta brunnea through a false rendering into Latin of 
“ Atlante brune ” of the French authors. An excellent distinctive feature of this species, 
overlooked by the authors, are the fine spiral raised lines which are visible on both sides 
of the spire but not upon the last whorl. This character will assist in distinguishing it 
from Atlanta turriculata, d’Orbigny, an allied form.
