94 AURICULELLA, OAHU. 



absent in the adult. As in all related species the lower colu- 

 mellar lamella is the more strongly developed, 



Oahu: Mt. Konahuanui, at about 3,000 feet (Cooke) ; Kuli- 

 ouou (Thaanum). 



In size this species approaches A. tenella Ancey. It differs 

 in proportion of length to breadth, in its much thinner shell 

 and in the serrate parietal lamella.

1 'Shell sinistral, ovately turrited, somewhat solid, slightly 

 striate, glossy, corneous chestnut, spire turrited, somewhat 

 obtuse ; suture impressed, marginate ; whorls 8, somewhat flat, 

 the last a little more than one-third of the length, carinate ; 

 parietal lamella strong, white, entering spirally; columella 

 twisted above and callously thickened; aperture oblique, re- 

 versed auriform; lip unexpanded, external margin acute, 

 columellar margin slightly thickened. Length 8, diam. 4 

 mm. ; aperture 3 mm." (Pfr.).

 Cooke, Pilsbry).

"Differs from T. petitiana in color, sculpture, carination, 

 and not dentate columella. It appears to be more related to 

 T. sinistrorsa Cham., but is sufficiently different in its tur- 

 rited form" (Pfr.). 



As already stated by Mr. Ancey, the type is not quite adult, 

 as the outer lip is thin and unexpanded, and the last whorl is 

 carinate. In adults the peristome is noticeably expanded and 

 the periphery is rounded.
