June 1847. Expedition Shells, 41. 
Suey large, rather solid, opaque, obovate, of a pale olive-green, 
with numerous longitudinal, zigzag stripes of a dark colour; surface 
rather rude. Spire composed of six convex whorls, the last of which 
composes nearly the whole of the shell, and is broadest behind 
the middle, whence it gradually narrows anteriorly, and descends 
abruptly to the suture posteriorly, forming a faint obtuse angle. Aper- 
ture three-fourths the length of the shell, elongated ovate, much less 
curved on the columellar side; columella white, broadly flattened, 
nearly straight, so that the tip passes from it, in front, in an angular 
manner. Interior of a pale, livid flesh-colour. 
Length seven-eighths of an inch; diameter half an inch. 
Obtained from the river Concon, Quillota, Chili. Couthouy. 
In size and marking it is similar to Chzlina major, Gray ; but is less 
broad, and the suture much less impressed. It is much larger and 
more ventricose posteriorly than C. pulchra, D’Orb., and much less 
pictured. ‘The columella is more acute and simulates another tooth.
