Succinea avara Say. From a pond near Braidentown. Is more 

 likely S. oralis Say. 



Natica sagraiana D'Orb. Several shells were found at Tortugas. 



Gundlachia ancyliformis Pfr. Three shells of this Cuban species 

 were found in a hammock near Palma Sola. 



Natica [semisulcata Gray, var. ?) Fordiana, n. s. 



Shell small, conic globose, white and shining throughout; whorls 

 well rounded, plicately striate below the suture, where they are encircled 

 by about six faint linear sulcalions, giving the spire and upper part of 

 the body whorl a slightly decussated appearance ; suture well impressed ; 

 umbilicus open, bounded by a sulcus; columella only slightly callously 

 thickened; operculum corneous. Length .40 inches; diam. .30 inches. 



Some twenty or thirty specimens of this fine little species were taken 

 alive on sand-flats in Sarasota Bay, during a severe norther, in a locality 

 laid bare only by heavy storms. I take great pleasure in naming it 

 in honor of my friend, Mr. John Ford, of the Academy of Natural 

 Sciences, of Philadelphia, who compared the shells of this type with the 

 Naticas of the Academy's collection, and determined it to be new. It 

 belongs to the subgenus Lunatia.
