GASTEROPODA. 19 
Length of axis three-fifths of an inch ; greatest breadth three-eighths, 
lesser breadth one-fifth of an inch. 
Found by Mr. Couthouy, at Tahiti, on wild sugar-cane, at elevations 
of from 250 to 4000 feet. 
About the size of S. amphitia, and well characterized by the an- 
gular shoulder of the last whorl. The aperture is peculiarly broad on 
account of the outward sweep of the lip. 
Figure 19, front of the shell; 19 a, lateral view of the shell.

Succinea infundibuliformis, Goutp ; Proceed. Boston Soc. Nat. Hist., 
ii. 186. Nov. 1346. Expedition Shells, 30. 
Anima “pale ochreous, finely dotted with black on the head, neck, 
and posterior extremity.” [s. Pp. c.] 
SHELL rather firm and opaque, in the form of an acute cone obliquely 
truncated at base, distinctly and somewhat regularly marked by dis- 
tant strie of growth. Colour pale greenish. Spire mammillate at apex, 
composed of two and a half flattened or even concave whorls, scarcely 
defined by the suture. Aperture broad-ovate, two-thirds the length 
of the shell, the columellar portion of the lip inflexed, not sinuate, in 
some instances having a distinct marginal carina, in continuation of 
the suture, at the posterior angle of the aperture, quite round to the 
base of the shell. Interior displayed to the apex, silvery white. 
Length of axis seven-tenths of an inch; breadth seven-twentieths of 
an inch. 
Inhabits the mountains of Tahiti and Eimeo at an elevation of 1000 
to 2000 feet, where it is often found on the stems of Fehis.
