oviformis Deshayes, 1830 , Ampullaria

( Fig. 5F )

Ampullaria oviformis Deshayes, 1830: 34 .

CURRENT TAXONOMIC STATUS. — Pomacea (Pomacea) . Valid species.

TYPE SPECIMENS. — Syntypes MNHN 4512 (1 spm), 5285 (1 spm).

TYPE LOCALITY. — “ Cayenne ” [ French Guiana;? error; Tillier 1980: 16] .

REMARKS

The two specimens are different species.Neither specimen is as large as the dimensions given in the original description (“Elle est longue de soixante millim. et large de quarante-huit”), as noted byTillier (1980: 16). MNHN 4512 corresponds to the written description in terms of the appearance of the shell ; MNHN 5285 does not, although its label says “type”. MNHN 5285 corresponds closely to syntypes of Ampullaria rufilineata Reeve, 1856 ( NHMUK), but correct taxonomic assignment of these syntypes and possible designation of a lectotype must await further research .
