Fam. OLIVIDAE. 



Genus Anciila, Lamarck. 



An cilia sp. 



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

 Ancilla 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.
