^a^.-^Sand Hills, between East and West Maui, with Leptachatina 

 extincta and Tornatellina extincta (Baldwin). 



This species has been discovered in a fossil condition only, but may 

 still be living in the island. It is thick for the genus, and the last 

 whorl is more or less stained with red towards the aperture.

Sah. — Waimea, Hawaii (Prof. Lyons). 



This fine, very thin-shelled species and the next are remarkable on 

 account of the very striking manner of coloration ; nothing like it has 

 been hitherto recorded in the genus. Another species, S. Newcombiana, 

 Garrett, has been described from the same district of Waimea ; since 

 the description appears to have escaped the notice of all subsequent 

 writers on the subject, and as it was omitted in my paper on the 

 Succinece of the Archipelago, I take the opportunity of transcribing 

 it here. 



" Succinea Newcomliana, Garrett. — Shell wide-ovate, very thin, 

 fragile, somewhat inflated, pellucid, whitish horn-colour; body-whorl 

 very large and distinctly striated ; spire very small, depressed, with 

 one volution ; aperture suborbicular and nearly the whole length of 

 the shell ; outer lip much expanded. 



"Length : three lines. 



" Animal pale flesh-colour, mantle obsoletely fasciated and slightly 

 reflected over the shell. Foot narrow, elongated and minutely 

 speckled with brown. 



"Habitat : District of "Waimea, Hawaii. 



"Observation: This singular species is somewhat rare, and occurs 

 on bushes at an elevation of about four thousand feet above the level 

 of the sea. This species is dedicated to Dr. "W. Newcomb, late of 

 Honolulu, S.I." (Garrett, in Proc. Ac. Nat. Sci. Cal., 1857.)
