Melania Vainafa, Gouin; Proceed. Boston Soc. Nat. Hist., ii. 224. 
June 1847. Expedition Shells, 46. 
Anima small, chestnut-colour above, faintly lineated with dusky ; 
proboscis long; tentacles slender, somewhat annulated; eyes sur- 
rounded with whitish; foot beneath orange, with cream-coloured 
dots, the points of the mantle very small; anterior angles of the foot 
a good deal dilated ; operculum ovate-rounded. 
SHELL long and slender, surface smooth, of a deep brown colour 
in old specimens, but of a yellowish-green colour, with longitudinal, 
flexuous pencillings of dusky, in young specimens. Spire eroded at 
tip, and with about four or five flattish whorls remaining. On the 
last whorl, and occasionally on some of the others, are seen a few dis- 
tant revolving lines, either raised or depressed. The suture is mode- 
rately marked, and usually margined. Aperture about one-fourth the 
length of shell, regularly ovate, the anterior point scarcely produced 
beyond the regular curve. Interior bluish. 
Length seven-eighths of an inch; breadth three-tenths of an inch. 
Obtained at the falls of Vainafa, island of Upolu, Samoa Group.

It has the form and general colour of small, smooth specimens of 
M. virginica, but the whorls are more flattened, and the front of the 
aperture is more rounded.
