92 LATIBUS. 



L. Catohuesonicus, Sowb. PI. 69, fig. 147. 



Purplish brown, same color within the aperture; columella 

 bicostate. Length, 16 mill. 



Key West, Florida ; St. Thomas, W. 7.— R. Swift, 



There are four immature specimens of this ver}'- 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 j'-ellow 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, Duukcr. PI. 69, fig. 150. 

 Brown, with the revolving lirae whitish ; aperture rosaceous. 



Length, 22 mill. 



Japan. 

 L. BREVicAUDATUS, Recve. 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. JUamentosua, 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. Croix, West Indies. 



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

 Swift Collection.
