278 FAUNA HAWATTENSIS 
“Tt 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, JJacrochlamys 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).

Has. Kauai (Gould).-—Maui, Haleakala, 5000—go0o0 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.

Fitzinger's type, as I understand him, was dzaphana Studer. 
Until the anatomy of these Hawaiian species is known, I can suggest no better 
reference than to the present genus.
