ANCEY : NON-MAHINE HAWAIIAN MOLLITSCA. 273 



Allied to S. canella, Gould, of Maui, and S. Konaensis, Sykes, 

 of Kona, Hawaii. Prom the latter it is quite recognizable, being of 

 a warmer colour and less produced spire. It is dedicated to my 

 late distinguished friend and co-worker, Mr. A. Grarrett, of Huahine, 

 Society Islands.

Hah. — Waianae Mountains, Oabu (Baldwin). 



In form it resembles S. pallida, Pfr., of the Society group, and it 

 is quite distinct from any pj)ecies hitherto detected in the Hawaiian 

 Islands.

Testa ovalis, tenuis, pellucida, succineo-lutea, lineis incrementi 

 Isevibus irregulariter impressa. Spira sat producta, conica, apice 

 minuto, papillari, f longitudinis totius adsequans. Anfractus 3, 

 convexi, sutura impressa et satis descendente discreti, rapide 

 crescentes ; ultimus ovato-oblongus, subobliquus. Apertura leviter 

 obliqua, regulariter ovalis, superne subangulata. Peristoma simplex, 

 acutum, hand expansum, margine externo arcuato, columellari 

 arcuato, simplici, tenui. Long. 11, lat. 6*25 mm. ; alt. apert. 7'5 mm. 



Sah. — Waimea, Hawaii (Prof. Lyons). 



This species, although of a simpler character than the preceding 

 one, is different from all the Hawaiian species with which I am 

 acquainted. As compared with S. Waianaensis, it is smaller and 

 thinner, and the suture is not so oblique, the spire being less 

 produced and papillose. 



15. Melania Baldwini, n.sp. PI. XII, Pig. 6.

 acuta. Anfractus 12, convexi, sutura canaliculata divisi, superiores 

 lineis incisis spiralibus numerosis et lineis incrementi iiexuosis et 

 costulis magis obsoletis crebre decussati, 3 ultimi infra suturam omnino 

 Isevigati, postea lineis incisis spiralibus sat distantibus regulariter 

 perarati, intervallis plus minusve crispulatis. Apertura oblonga, intus
