Viviparus Georgianus - Original Description

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:

    “A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.”
    —Freeman Dyson (b. 1923)

    “I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
    —Thomas Jefferson (1743–1826)
