ANCEY : LAND SHELLS FOUND IN HAMAKUA DISTRICT, HAWAII. 67 



7.— Endodonta hystrieella, ph. var. paueilamellata. n. vai. 

 PI. V, fig. 17. 



Testa orbicularis, rotuliformis, convexo-depressa, aperte sed mediocriter 

 unibilicata (umbilicus circa i millim. latus), subfossilis alba, late fulvo 

 strigata, strigis in ultimo anfractu fulminatis ; costulis acutis, subarcuatis, 

 dehinc flexuosis ornata ; spira convexa, parum elevata, apice planato ; anfrac- 

 tus 5 convexi, regulariter crescentes, sutura perimpressa, ultimus cylindricus, 

 in adultis supra medium ad aperturam plano-declivis : apertura obliqua, 

 lunato-rotundata, marginibus acutis baud expansis, pariete laminis volvent- 

 ibus 2, supera paulo validiore munito. 



Diam. maj. vix 5, min 4^ ; alt. 2 millim. 



I have not been fortunate enough to procure authentic specimens of 

 E. hystrieella, but refer to Pfeiffer's species some shells from Makawao, 

 Maui. These have, however, three palatal laminae, while in the subfossil 

 form there are more. Hence these are possibly specifically distinct, as more- 

 over the true E. liydricella has not yet been found on Hawaii. However, 

 I prefer to subordinate them to the latter, because besides the laminae there 

 are not many differences. It is right to observe that in some allied forms 

 the palatal laminae present in typical examples are reduced in number or 

 even wanting in others. I am tlertfore confident that Nefopliila, Pilsbry, a 

 sectional name based on that feature, has no value whatever, unless it may 

 be retained for Helix tiara, Mighels, a large form of quite a distinct type, 

 from the island of Kauai. In general shape and contour this is much like 

 Stephanoda dissimilis, d'Orb., from Chili, but the palate is furnished with 

 small parallel and numerous revolving lirae. 



8.— Endodonta lanaiensis, Sykes. 

 A single good specimen. Greatest diam. 4, high ih millim. 



9 — Nesopupa acanthinula, Anc. 



Rare, but frequent in a living state in Oahu, Hawaii, and probably 

 other islands. 



10.— Nesopupa, sp. 

 A single broken specimen, with the teeth of Pupa neircomhi, but larger 

 and more elongate. A similar but smaller form is found living on Oahu 

 and Hawaii. 



11.— Nesopupa baldwini, Anc. var. centralis, Anc. 



Also found living at Olaa, Hawaii (Thaanum). This and others men- 

 tioned in the present paper will be fully illustrated in other contributions to 

 the malacological fauna of the Hawaiian islands actually in the press. The 

 typical specimens, with a more produced spire of 5^ whoils are from Molokai 

 and Maui.
