H. PKOFUNDA. — Plate 37, fig. 3. As in Journ. Acad. My 
description of this shell was published in the year 1821. Lamark’s 
description of H. Richardi did not appear until April, 1822, but 
he quotes, by anticipation Ferussac, Hist, des Mollusques, No. 174, 
for the specific name, which was, however, not then published in 
that work, but appeared in the Tableau Systematique of the latter 
author in the earlier part of the same year. The name of pro- 
funda has therefore the priority, and consequently must be 
adopted.

Helix lucubrata. — Shell subglobose, depressed, reddish 
brown, polished, subtranslucent whorls over four, much wrin- 
kled ; spire much depressed, convex ; suture moderate ; beneath 
paler •, umbilicus open, rather large 3 aperture nearly orbicular ; 
labrum simple. 
Greatest width one inch. Inhabits Mexico. Closely allied to 
H. inornata. Nob., but the umbilicus is much larger, and the 
aperture is more accurately rounded 3 the color is nearly the same, 
excepting that in the present it is of a deeper shade.
