H. PROFUNDA. — Plate 37, fig. 3. As in Journ. Acad. My 

 description of this shell was published in the year 18^1. 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. 



No. 5.— August, 1832. 

 Helicina orbiculata. — Plate 46, f. 1, 2, 3. Same as Oligyra 

 orbiculata, Nicholson Encycl. 



H. occulta. — PI. 40, f. 4, 5, 6. Same as Trans- Journ. Med. 



No. 6.— April 1834. On the cover. 



It seems probable that Helix irrorata is a variety of H. 

 lactea. Mull., with which I compared it when describing it. 



Caracolla helicoides, Lea. — Trans. Am. Phil. Soc. vol. iv. 

 N. S., is variety a, of Helix palliata, Say, H. denotata, Fer. 



Helix carolinensis, Ibid. — Corresponds by descriptions and 

 figures with H. appressa. Say, Var. a. 



No- 5 and 6. — Descriptions of some new Terrestrial and 

 Fluviatile Shells of North America, &c. 



Helix lucubrata. — Shell subglobose, depressed, reddish 

 brown, polished, subtranslucent ; whorls over four, much wrin- 

 kled ; spire much depressed, convex ; suture moderate ; beneath 

 paler 9 umbilicus open, rather large ; 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 mor« accurately rounded ; the color is nearly the same, 

 excepting that in the present it is of a deeper shade. 



H. SUPPRESSA. — Shell subglobose, depressed, pale horn color, 

 poliihed, somewhat pellucid -, body whorl opake, whitish near the
