Gastrocopta pentodon (Say, 1822) form carnegiei (Sterki, 1916) |
||
|
Described as a distinct species, this morph is characterized by (1) its lack of callous apertural rim bearing several denticles and (2) possession of inset/penetrating palatal and infrapalatal lamellae. Hubricht (1968: 6) wrote "occasionally a specimen of G. pentodon will become mature and develop the teeth one whorl short of the usual number. Such specimens were named Gastrocopta [sic; actually Bifidaria] carnegiei by Sterki. Gastrocopta tappaniana produces similar aberrations." Aberrant process notwithstanding, this form is quite a handsome and distinctive shell. |
