Cudmore Collection. 



Class GASTEROPODA. 

 Fam. TROCHIDAE. 



Genus Astele, Lwainson. 

 Asfele sp. 



Several casta and moulds of a form referable to the above genus; 

 occur in the white limestone. It has rather smooth, flat whorls, and 

 a thread-like ornament round the base. It resembles an unde-

Fam. NATICIDAE. 



Genus Natica, Scopoli. 

 Nafica substol/c/a, Tate, var. fji'dndis, nov. 



Description. — Shell of the type of Xatico suhsiolida , Tate,^ but 

 of much larger dimensions and heavier build, the length being 

 more than twice that of the specific form (54 mm., as compared 

 with 25 mm. in the species). 



A large specimen of Natica, somewhat deformed, but evidently 

 belonging to the new variety, has been figured by Mr. C. J. Gabriel 

 and the writer from the Mallee Bores, under the name of N. suhin- 

 fundihuhun, var. crassa, Tate.^ 



Ihis large variety is fairly common in the limestone of the 

 Ooldea district, and its large size (over 2 inches in length), makes 

 it a conspicuous fossil.
