Ampullaria lemniscata Crosse & Fischer in Fischer & Crosse, 1888: [explanation of] pl. 44, figs 5, 5a-c [ Crosse & Fischer 1890: 112, 248].

CURRENT TAXONOMIC STATUS. — Pomacea (Pomacea) . Synonym of Ampullaria flagellata Say, 1829 ( Cowie & Thiengo 2003: 67).

TYPE SPECIMEN. — Holotype MNHN 4615 .

TYPE LOCALITY. — [ No locality given; “coloniâ anglicâ Belize ” ( Crosse & Fischer 1890: 112)] .

REMARKS Cowie & Thiengo (2003: 67) noted four specimens they considered as syntypes. However, the original publication conferring availability of Ampullaria lemniscata was an illustration (with name) of a single shell. One of the four shells has “type” written on it; a label associated with it says “type” and says that it is the shell figured; it also corresponds to the illustration very well. We consider this shell the holotype, by monotypy. The other three specimens (MNHN 5142) have no type status, contrary to Cowie & Thiengo (2003). Sowerby (1909: 363) also reported finding type material of Ampullaria lemniscata in the MNHN.
