DEFRANCIIN^. 95 



Sub-fam. DEFEANCIIN^. 



Operculum none. 



Genus DEFRANCU, Millet. 



Shell turreted, fusiform; spire elevated, whorls cancel- 

 lated ; aperture oval ; canal short ; outer lip with a slight 

 emargination or sinus at its junction with the body- whorl. 



Ex. D. teres, Forbes^ pi. 10, fig. 7. Shell, D. linearis, 

 Montagu, fig. 7, a. 



Defrancia may be considered as cancellated ^langelia, 

 with the body-whorl more ventricose, and the canal slightly 

 more evident. The want of operculum, and the nature of 

 the emargination of the outer lip, at once distinguish it 

 from Clavatula, and the texture and sculpture of surface 

 from Bela and Daphnella.
