Partulina kaaeana BALDWIN, Nautilus xix, p. 113, February, 

 1906. 



A dull brown shell, yellow-banded below the periphery, 

 speckled with whitish flecks, or with the last whorl having only 

 some indistinct flecks and streaks, dark on each side of the light 

 band. Another specimen is reddish brown with many irregular 

 streaks and spots of white, but without the subperipheral light 

 belt. The last embryonic whorl is striped white and brown, 

 as usual. While related to marmorala, this is a quite distinct 

 species. Figured from the type lot. 



"This shell was found on a mountain peak quite isolated 

 from the main mountain mass of West Maui. We dedicate it 

 to Mr. W. F. Kaae who seems to have been the only one in

 found the shell in company with Perdicella ornata Nc., a species 

 supposed long since to have become extinct," (Baldwin).

 epidermis. Aperture moderately large, ovate, the lip slightly
