Dec. 1846. Expedition Shells, 32. 
SHELL rather solid, elongated-ovate, turreted, smooth, polished, 
somewhat indented, the lines of growth scarcely apparent, encircled 
by very fine, rather distant parallel lines. Colour dark chestnut, with 
nearly an equal proportion of gamboge-coloured blotches, which are 
arranged in somewhat oblique series, sometimes even in stripes; ro- 
seate towards the apex. Whorls six, rather convex, separated by a 
well-marked, margined suture, the last one large, and slightly com- 
pressed from before backwards, and having an obtuse keel near the 
base, and a channel running to the umbilicus between it and the lip. 
Aperture long, narrow rhomboidal, and somewhat channeled at base ; 
lip broadly reflected, of a rich reddish-purple, nearly continuous pos- 
teriorly ; throat rosy purple. 
Length of axis one and three-fourths of an inch; diameter five- 
eighths of an inch. 
Obtained at Rio Janeiro.
