Carelia cumingiana ssp. cumingiana (Pfeiffer)

Cuming’s Carelia Snail (Carelia cumingiana ssp. cumingiana)

Cuming’s Carelia Snail was described in 1855; the exact origin of this form is not known, but it is believed that it came from the Lumaha’i valley near the northern coast of Kaua’i, Hawaiian Islands.

The shells of this form reach heights of 3.7 to 4.8 cm.

… the original forest which was probably occupied by this species was destroyed by fire or cattle many years ago. Since most of the species of Carelia occupy rather restricted colonies, I feel certain that the typical form of this species must be considered extinct. From the close similarity of the specimens, I feel sure that all came from a restricted colony and that at the time they were collected they were fairly abundant.” [2]
