Original Description
Viviparus georgianus was originally discovered and described (under the name Paludina georgiana) by Isaac Lea in 1834.
Lea's original text (the type description) reads as follows:
| “ |
Paludina Georgiana. Plate XIX. fig 85 Testa ventricoso-conoided, tenui, tenebroso-cornea, lævi; suturis valde iinpressis; anfractibus instar quinis, convexis; aperturâ subrotundatâ, albâ. Shell ventricoso-conical, thin, dark horn coloured, smooth; sutures very much impressed; whorls about five, convex; aperture nearly round, white. Hab. Hopeton, near Darien, Georgia. Professor Shepard. My Cabinet. Cabinet of Professor Shepard. Diam. • 7, Length 1•1 inches. Remarks.—This species, in form, resembles most, perhaps, the P. vivipara. It is not quite so large, nor has it bands. It is rather more elevated, and the body whorl is smaller and rounder than the P. decisa (Say). The aperture at the base recedes more than is usual with this genus. |

Famous quotes containing the words original and/or description:
“Painting myself for others, I have painted my inward self with colors clearer than my original ones. I have no more made my book than my book has made me—a book consubstantial with its author, concerned with my own self, an integral part of my life; not concerned with some third-hand, extraneous purpose, like all other books.”
—Michel de Montaigne (1533–1592)
“I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.”
—Henry David Thoreau (1817–1862)
