Length, 5 inm. 



Described from a fossil shell of the Pliocene. 



The shell is white, semi-transparent. The animal is 

 unknown. Specimens before me from Foveaux Strait and 

 Chatham Islands are much smaller than the fossil forms. 



Length, 3 mm. ; breadth, 1-5 mm. 



Type in the Canterbury Museum. 



Hah. Foveaux Strait (A. Hamilton). Chatham Islands. 



Daphnella substriata, n. sp. Plate III., figs. 6, 6a. 



Shell thin and fragile, small, oval-fusiform, spire longer 

 than the body-whorl, white, apex light-violet, finely spirally 

 striated throughout, except the protoconch. Whorls 6, 

 rounded, with delicate equal and numerous fine spiral striae. 

 Protoconch mammillary, rounded, smooth, light-violet. Suture 

 superficial, submargined. Aperture elongated oval, outer lip 

 simple, sharp, slightly sinuous, posterior sinus but faintly 

 indicated. Columella concave, with a thin shining callus; 

 anterior canal short, broad, truncated, slightly recurved. 

 Animal unknown. 



Length. 5*5 mm. ; breadth, 2-25 mm. ; height of aperture, 

 2-25 mm. 



Type in my collection. 



Hab. Foveaux Strait (A. Hamilton). 



Very closely allied to D. striata, Hutton, of the New 

 Zealand Pliocene, but this species is of much larger size 

 (length up to 30mm.), the protoconch is keeled, and the fol- 

 lowing whorls are slightly shouldered ; the spiral strise are 

 unequal, broader ones alternating with smaller ones ; the 

 incremental strise are much more conspicuous, and the an- 

 terior canal is mostlv longer and narrower.
