Carinated River Snail—middle figures.
P. testâ parvâ, olivaceâ; spirâ aperturâ longiore, apice obtuso, rufo; anfractu basali medio leviter carinato; umbilico obsoleto.
Shell small, olive; spire longer than the aperture; the tip obtuse, rufous; basal whorl slightly carinated in the middle; umbilicus obsolete.
A distinct species, which is never found larger than the figure. I once saw near 100, which had been picked up on the banks of the Ganges; the spire is rather lengthened, always obtuse, and the umbilicus even less than the last.
