706 GASTROPODA. [Pidmonata. 



Jaw (Plate 1, fig. 17) finely striated, arcuated, with a, slight median 

 projection. 



Radula (Plate 1, fig. 17) having the formula 13 + 1 + 13, varying 

 from 12 to 15 ; laterals 4 or 5. Central tooth tricuspid, the mesocone 

 reaching about to the posterior border of the basal plate, side cusps 

 small. Laterals similar, but somewhat asymmetrical, the entocone 

 becoming larger outwardly until it becomes joined at the base with 

 the mesocone. The ma,rginals are very low and wide, by shortening 

 of the basal plates ; tricuspid, the ento- and meso-cone often joined 

 at base ; ectocone smaller, simple or split into two. Cusps variously 

 degenerate on the outermost marginals.

White specimens, from Kenepuru, are in my collection. Only one 

 specimen shows traces of light-brown streaks on the earlier whorls, 

 the others having no colour-markings at all.
