224 PROCEEDINGS OF THE ACADEMY OF [1895. 



Length, 14*; diarn. 9 mm. 



Habitat, Makawao, Island of Maui. 



Animal when extended in motion longer than the shell. Mantle 

 light brown mottled with black, outer edge encircled with an in- 

 terrupted orange band. Foot above and below a very light brown, 

 superior portion witb a slate tinge, posterior portion tapering and 

 sometimes with a yellowish tinge. Tentacles long, light slate. 

 Head above minutely granulated. 



This species was collected in the forests of the exterior slope of 

 the extinct Haleakala crater, at an altitude of 4,000 feet above sea 

 level. Owing to its peculiar habit of living on the foliage near 

 the tops of trees, it has escaped previous observation. 



The species has no known congeners. It is remarkable for the 

 constancy of its delicate color lines. Over 200 examples before 

 me show only trifling divergence in this respect. 



Named in honor of Mr. C. F. Ancey, whose publications have 

 contributed largely to our knowledge of Hawaiian land shells.
