having also seen the animal, I have detected no difference. 

 The following are extracts from his notes: '• Feb. 1843. I 

 find on the bushes, on the side hill above the fort (Matanzas) 

 some of this species. They are not so well marked as those 

 found in the interior ; these are a dun or cream-color, the 

 bands and cross markings in most specimens quite obscure." 

 Again, " these shells have no transverse marks like those 

 found on the Carolina, but are evidently the same species. 

 These are of various colors, some ashy-white, others dun ; 

 some have two obscure brown bands on the body whorl, 

 while on others the bands are quite distinct." 



Helix fragilis, Pfeif. ; JViegm. Archiv, 1839-40. 



These appear somewhat immature, though they were found 

 dead. They resemble the young of H. auricoma and H. 

 Bon2)Iandn, but are much more rough " like a file." 



Found in the woods under leaves, and among stones on the 

 limestone knobs, on the Carolina, Retiro, and Mt. Vernon 

 estates. 



Helix Boothiana, Pfeif. ; Wiegm. Archiv, 1840. 



Helix Ottonis, Pfeif. ; Wiegm. Archiv, 1839. 



Helix saxicola, Pfeif. ; JViegm. Archiv, 1839. 



Found on trees, in the crevices of the bark, at La Carolina. 



Helix septemvolva, Say. Near Matanzas. 



Helix Ramonis, D'Orb., 3IoIL de Cuba, plate viii. fig. 1-4. 



Animal, light horn-colored, with two darker lines behind 

 tentacles. These are short, black, somewhat dilated near 

 base ; back beautifully granulated. V 



This belongs to the group named Polygyra by Say, and 

 somewhat resembles H. septemvolva. Perhaps the peculiar 

 form of the tentacles will be found constant in all species of 

 the group. 



Found near Matanzas.
