2 78 FAUNA HAWAIIENSIS 



" It will be seen from the above characters that this species cannot be placed in the 

 Helicarionidae — the absence of shell-lobes forbids this. Aculeate laterals are hardly 

 ever met with even in the genera of Zonitidae possessing shell-lobes ; I can only recall 

 one species, Maci'ochlamys castaneolabiata. The solid jaw, divided foot, and, in all 

 probability, the presence of a mucous gland place it in the Zonitidae. In so many 

 points is it distinct from any of the Indian and Malayan forms that I am acquainted 

 with that I the more regret that the generative organs have still to be made out" 

 (H. H. Godwin-Austen).

 Moll. 1856, pi. I. fig. 10. 



Hab. Kauai (Gould). — Maui, Haleakala, 5000 — 9000 ft. (Perkins). 



The specimens found by Mr Perkins appear to be identical with Gould's species, 

 which, so far as I can trace, has not been rediscovered on Kauai. In fresh specimens 

 the lip is margined with black. 



ViTREA Fitzinger. 



Vitrea Fitz., Beitr. Landeskund. Oesterr. iii. p. 99. 



Fitzinger's type, as I understand him, was diaphana Studer. 



Until the anatomy of these Hawaiian species is known, I can suggest no better 

 reference than to the present genus.
