258 TORNATELLARIA. 



In the ananeanic and metaneanic substages there are two 

 equal columellar lamellae, but the lower one then diminishes. 

 This species was taken in large numbers in the " Endodonta 

 colony ", among dead leaves on the ground.

T. newcombii is distinguished by its very narrow umbilicus, 

 two emerging columellar lamellae, the whitish corneous tint, 

 and by having the base less shortened than in other known 

 Oahuan species. 



This species is limited to the islands of Kauai and Oahu. 

 On the former island it has been taken in two localities only. 

 It is abundant on the whole Koolau range of Oahu but is 

 seldom met with in the Waianae mountains except on the 

 western slope above Waialua. 



The specimens from Honolua, W. Maui, which Mr. Ancey 

 referred to this species, are young T. cincta Anc. (Bishop 

 Mus. Coll.no. 18479). 



The fossil form reported from Hawaii is distinctly T. 

 trochoides. 



The type specimen in the British museum is not quite ma-
