SowERBY, Pro. Zool. Soo. 1832, p. 113. 



Hah. Bay of Panama (found on dead shells in ten fathoms) ;

 Curiously distingui.?hed from all other species of the 



genus by its channel-winged aperture, which gives tiie 



shell a characteristic harp shape.

Gaskoin, Pro. Zool. Soc. 18-18. 



Bab. Payta, Peru. 



Obliquely sculptured throughout with narrow ribs de- 

 scending with the angular declivity of the whorls.

Hab. Panama and Xipisapi (under stones) ; Cuming. 

 A strongly tubercled chalk-white shell, pied with one 



or two large black blotches. 



Fig. 33. (Fig. «, b, Mus. Cuming.) 

 This shell, though so unlike the preceding in appearance, 

 is nevertheless a variety, in which the tubercles are modi- 

 fied into concentric sutural ridges. 



Species 3-1. (Fig. a, b, Mus. Cuming.) 

 Columbella flexuosa. Col. testa fusifarmi-ablongd,
