L. CAYOHUESONICUS, Sowb. PL 69, fig. 147. 



Purplish brown, same color within the aperture ; columella 

 bicostate. Length, 16 mill. 



Key West, Florida ; St. Thomas, W. I.R. Swift. 



There are four immature specimens of this very recently 

 described species in the Swift Collection. In one of them there 

 is a broad lighter band below the periphery. 



L. NODATUS, Martyn. PI. 69, fig. 148. 



Orange-brown (light yellow under the epidermis) ; the aperture 

 roseate. Length, 2*5-3*5 inches. 



Sandwich and Viti Islands, etc. ; Panama. Cuming? 



The last locality is doubtless erroneous, as it has not been con- 

 firmed by any collector subsequent to Cuming 



L. VARICOSUS, Reeve. PI. 69, fig. 149. 



Light orange-brown, the ribs dark chocolate-brown; aperture 

 yellowish or blush. Length, 2*5 inches. 



Galapagos Is.; in crevices of rocks. Cuming. 



L. RHODOSTOMA, Dunker. PI. 69, fig. 150. 



Brown, with the revolving lirse whitish ; aperture rosaceous. 



Length, 22 mill. 



Japan. 



L. BREVICAUDATUS, Reeve. PI. 69, figs. 154, 151. 

 Reddish brown, the revolving cords dark chestnut-brown ; 



aperture yellowish brown. Length, 1*5-2 inches. 



West Indies. 



Most of the specimens before me have a well-marked posterior 

 channel in the aperture. L. filamentosus, Koch (fig. 151), is a 

 synonym, perhaps, but the only figure is evidently a very poor 

 one, and hardly to be identified with certainty. 



L. CONTEMPTUS, A. Ad. PI. 69, fig. 152. 



Reddish brown, with darker revolving lines ; yellowish within 



the aperture. Length, 1*25 inches. 



St. Groix, West Indies. 



I have not seen this species ; there is nothing like it in the 

 Swift Collection.
