SYKES : NEW HAWAIIAN NON-MARINE MOLLUSC A. 299 



angustus, pcrvius " : in short, I can trace no material differences 

 between them. There appears, therefore, to be a compact little group 

 of three species — one from Maui, one from Molokai, and one from Lanai. 

 Vitrea MoloJcaiensis may be at once separated from V. pauxillus by its 

 wider and more open umbilicus, and by the fact that the sculpture is 

 strongly continued over the base ; while V. Lanaiensis is intermediate 

 in the umbilical perforation, and is a more compressed shell than 

 V. pauxillus. 



3. Kaliella Konaensis, n.sp. 



Testa conico-pyramidalis, brunnea, subtenuis, subimperforata, supra 

 si;b lentc dense et obsoletissime lineis incrementibus sculpta, infra 

 Isevior, nitida ; spira bene elevata, apice obtusa, Isevi ; anfr. 5f , con- 

 Texiusculi, lente regulariterque accrescentes, sutura valde impressa, 

 ultimus ad peripheriam carinatus, basi inflatus ; apertura securiformis ; 

 peristoma simplex, tenue, acutum, margine columellari leviter reflexo. 

 Diam. max. 3*5, miu. 3-2 mm. ; alt. 2 mm. 



Rah.— lit. Kona, Hawaii, at 3,000 feet (Perkins). 



A remarkable little shell which seems to fall into KalieJla ; it may, 

 however, possibly be placed, when we are accpiainted with the 

 anatomy, near the Japanese forms of Trochoconulus. 



4. Succinea Konaensis, n.sp. 



Testa elongato-ovata, rugoso-striata, pellucida, pallide succinea, rare 

 rufescenti - succinea, spira elongato-conica, apice papilhxta, sutura 

 valde impressa ; anfr. 3^, rapide accrescentes, ultimo magno ; apertura 

 ovata, fere verticalis, columella subarcuata, peristomate acuto, basi 

 expansiusculo. Alt. 9*5, lat. 5 mm. 



Eab.—lli. Kona, Hawaii, at 4,000 feet (Perkins). 



The large number of unfigured species desci'ibed from the Hawaiian 

 Islands, renders the identification of specimens a somewhat difficult 

 task, but the present form does not appear to quite agree with any 

 named species.
