Felipponea elongata

Felipponea elongata is a species of large freshwater snail with an operculum, an aquatic gastropod mollusk in the family Ampullariidae, the apple snail family.

The original description[]

Felipponea elongata was originally discovered and described (under the name Ampullaria (Felipponea) elongata) by W. H. Dall in 1921.^[1]

Dall's original text (the type description) reads as follows:

AMPULLARIA (FELIPPONEA) ELONGATA n. sp.

Shell solid, conic, of three and a half flattish whorls separated by a distinct, almost channelled suture (the apex deeply eroded); shell substance grayish to slate color, with irregular broad spiral purple lines, the whole covered with an olivaceous, thick, polished, dehiscent periostracum of a brittle character; base rounded, umbilicus only a narrow chink behind the thin raised inner lip; aperture pear-shaped, smooth inside, showing the color bands; margin sharp-edged, not continuous across the body. Height of decollate shell 29; of last whorl 25; of aperture 17; of maximum diameter 19 mm. U. S. Nat. Mus. No. 333024.

Habitat. Uruguay River, Dept. of Paysandú; Dr. F. Felippone.

It is interesting to get another and quite distinct species of this subgenus which seems characteristic of Uruguay River fauna. The present species differs most obviously from the type, , in the flat-sided spire and absence of an

umbilicus.

Distribution[]

This species occurs in the Uruguay River in Uruguay.
