Auch über Ampullaria flagellata sind die Ansichten sehr geteilt. 
Martens (Biologia Centr. amer. p. 409) sagt über sie: „A very variable Shell, 
chiefly distinguished by its ovate form, with rather obtuse spire and superficial suture, 
the smooth and somewhat shining surface, with more or less numerous malleated 
impressions and the somewhat enlarged and expanded peristome, this being especially 
noticeable in the lower half of its outer side. It is generally of a yellowish-green 
(olivaceous) colour, more or less pale, somewhat darker in the lower half of the 
Shell; worn specimens become violet, as in most species of this genus, and in fresh 
Shells the upper whorls, having been exposed for longer time to chemically destroying 
agencies, are usually of a dark purple-brown, the peristome pale yellowish. The size 
is very variable, as in many species of freshwater Shells. A distinctly expanded 
peristome does not always denote that the Shell is full grown, for specimens occur, in 
which the remnant of an expanded peristome is to he seen about a half whorl back- 
wards of the aperture, as in the figure given by Jonas and in fig. 15 of Strebei.“
