388 FAUNA HAWAIIENSIS 



(17) Succinea Diatiiensis Ancey. 



Succinea mauiensis Ancey, Bull. Soc. Malac. France, vi. (1889), p. 248. 

 Hab. Maui (Ancey) ; Makawao (Baldwin) ; Haleakala at 5000 feet (Perkins). 



(18) Succinea newcombiana Garrett. 



Succinea newcombiana Garrett, P. Calif. Ac. 1. (1857), p. 103. 



A species closely related to S. ceptdla and 6". rotundata, but, if my identification of 

 the latter is correct, this is smaller, the mouth is rounder, and the last whorl not so 

 much inflated. 



Hab. Hawaii, district of Waimea (Garrett) ; Kohala Mountains (Perkins). 



(19) Succinea protracta sp. nov. 



Testa tenuis, aureo-rufa vel pallide-cornea, lineis increment! obliquis bene 

 notata ; spira producta, apice acutulo, mamillato ; anfr. 3^ convexi, sutura bene 

 impressa discreti, rapide accrescentes : apertura ovato-pyriformis, fere recta ; peristoma 

 simplex, tenue, margine columellari arcuato, haud plicato. Long. 127, diam. maj. 6; 

 alt. ap. 8, lat. ap. 5 mm. 



Plate XI. fig. 25. 



Belongs to the group of 5. auridenta Ancey, but is much more elongate and 

 slender, and the suture is more impressed. A single white specimen from ' Mauna Loa 

 at 3500' feet I also refer to this species. 



Hab. Hawaii, Kau (Perkins). 



(20) Succinea punctata Pfeiffer. 



Succinea punctata Pfeiffer, P. Zool. Soc. London, 1854 [May, 1855], p. 297; 

 Reeve, Conch. Icon. Succinea, fig. 29. 



The specimens from Kohala Mts. are young and have the spire slightly more 

 depressed, but appear to belong to this form. The white spots shewn in Reeve's 

 figure are much exaggerated : most specimens have a few blotches of a paler tint, but I 

 have seen none regularly spotted in the way the artist has represented them. 



Hab. Hawaii (Pfeiffer); Kohala Mountains, Olaa Puna, and Kona at 3000 feet 

 (Perkins).
