 and May, Proc. Linn. Soc, New South Wales, 1901, vol. 

 xxvi., part 3, p. 407, pi. xxiv., fig. 23 ?), or only one keel, or 

 two or three. The spiral lirae around the umbilicus may be 

 valid, when the three keels are marked, continuing their series 

 as lesser keels to the edge of the umbilicus ; or they may be 

 distinct and lamellose when the keels are absent. Spiral 

 striae are present from suture to umbilicus, and these vary much 

 in their visibility. Then the axial striae are sometimes obso- 

 lete, sometimes rather distant, sometimes distinct, crowded, 

 and erect, especially between the suture and the slit fasciole, 

 but also sometimes between the keels at the base.
