Original descriptions from the 1840s

Anguispira cumberlandiana was originally discovered and described under the name Carocolla Cumberlandiana by Isaac Lea in 1840.[2]

Lea's original text (the type description) reads as follows and provided one sentence of physical description. He lists the location of specimens as in the Cumberland Mountains near Jasper, Tennessee:

Carocolla Cumberlandiana. Testa lenticulata, carinata, striata, albid, fusco-notata, late umbilicata, ad carinam supern et inferne impressa; anfracti- bus quinis; apertura angulata, intus sulcata; labro acuto. Hab. Cumberland Mts., near Jasper, Tenn.-Dr. Currey.

Later, in 1843,[3] Lea provided the same description, but with more background information about the body form of this species in relation to H. alternata (now known as Anguispira alternata), particularly the lenticular form and carina of cumberlandiana.

CAROCOLLA CUMBERLANDIANA. Plate 6, Fig. 61. Testa lenticulata, carinata, striata, albidd, fusco-notata, lat umbilicata, ad carinam superne et infernk impressd; anfractibus quinis; aperturd angulatd, intus sulcatd; labro acuto. Shell lenticular, carinate, striate, whitish, brown-spotted, widely umnbilicate, impressed above and below the carina; whorls five; aperture angular, within furrowed; lip acute. Hab. Cumberland Mountains, near Jasper, Tenn. Dr. Currey. My Cabinet, and Cabinets of Dr. Currey and Mr. Edgar. Diam. .54, Length .14 of an inch. Remarks.-Among many species of land shells which I owe to Dr. Currey's kindness, were two individuals of this Carocolla, which does not appear to have been before noticed. It has some resemblance to H. alternata, (Say,) but may at once be distinguished by its depressed, flat, lenticular form and carina. It is a very interesting species, and has a remarkable furrow above and below the carina: all the whorls, are visible in the umbilicus, and are striate all over.
