Limnea volutata, Goutp; Proceed. Boston Soc. Nat. Hist., 11. 211. 
June 1847. Expedition Shells, 41. 
SHELL small, ovate, somewhat cylindrical, as if it had been rolled, of 
a fawn-colour, the surface deadened by numerous, somewhat irregular, 
lines of growth. Several of the apicial whorls are lost, and two or 
three only remain, which are somewhat more oblique than usual, not 
inflated, sloping in a gentle manner to the suture, which is but mode- 
rately impressed. Aperture broadly ovate, two-thirds the length of 
the shell, the columella of a palish-brown colour, and with a well-de- 
veloped fold. 
Length three-tenths of an inch; diameter one-fifth of an inch. 
Inhabits the Island of Oahu, Sandwich Islands. 
Much smaller than L. Oahuensis, Souleyet, and with less tumid 
whorls, slopmg gently to the suture. The somewhat cylindrical 
aspect of the shell is peculiar. 
Figures 142, 142 a, two views of the shell, enlarged; 142, natural 
size.
