Fam. OLIVIDAE. 



Genus Ancilia, Lauiarck. 



Ajicilla sp. 



A cast of a shell occurs in the limestone, of the type of an- 

 Ancilia found at Spring Creek and Table Cape (Nat. Mus. Coll.), 

 but of very large dimensions. It must have attained a length of 

 about 50 mm. when complete, whereas the Spring Creek specimens- 

 rarely measure more than 20 mm., a difference accounted for by 

 the variation in sedimentation. 



Fam. TURRIIIDAE. 

 Genus Clavatula, Lamarck. 



1 Clavatula sp. 



This is an internal cast of the apical portion of a large conical, 

 species, with the earlier whorls faintly costate and medially 

 ridged.

Fam. CONIDAE. 



Genus Conus, Linue. 

 Conus spp. 



Probably several species are represented here, but they are all- 

 internal casts. So far as can be seen, the commonest form is 

 related to Conns ligatus, Tate.^
