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



3.— Punetum horneri, n.sp. 



PI. V, figs. II, 12. 



Testa deprcssa, tenuis, orbicularis, emortua albida vel pallide fulvida, apice 

 pallidiore laevigata excepto striis exilibus incrementi subtiliter exarata ; spira 

 convexa, parum elevata, obtusa ; anfractus 4 convexiusculi, sutura impressa 

 discreti, regulariter atque lente crescentes, ultimus convexiusculus, circa 

 umbilicum mediocrem, quartam diametri partem paeno aequantem sub- 

 depressus ; aperatura suboblicjua, lunata, subrotundata ; peristoma acutum, 

 baud dilatatum, marginibus distantibus. 



Diam. maj. i, min. 1 ; alt. \ millim. 



This minute shell is closely allied to the European P. pij(jinapu)n, Drap. 

 It is also recent on Oahu. 



4.— Endodonta laminata, Pease. 

 PI. V, tigs. 13, 14. 



Not liilherto recorded from Plawaii. 'i'he specimens of this and the 

 following Eiidodontdr retain their usual coloured brown stripes on a pale 

 ground. 



5 - Endodonta (Thaumatodon) nuda, Anc. 



One or two imperfect examples seem to be referable to this species, 

 originally described from fresh specimens from Olaa, Hawaii. 



6.— Endodonta (Thaumatodon) henshawi, n.sp. 



Testa parva, orbicularis, emortua alba, vestigiis strigarum fuscarum 

 plerumque, sui)erne praesertim eleganter lateque maculata, costulis acutis 

 confertis (circa 45 in ultimo anfractu), radiantibus insculpta, baud nitida, 

 aperte et mediocriter umbilicata ; spira cunvexiuscula, parum elevata ; 

 anfractus 4 — 44 convexi, sutura impressa discreti, regulariter crescentes, 

 ultimus cylindricus, flexuose costulatus ; apertura parum obliqua, lunato- 

 circularis, in pariete laminis duabus volventibus et in interiore basis marginis 

 dextri denticulis 5 acutis aequidistantibus (2 superis soepe obsoletis) armata ; 

 peristoma simplex, ad columellam nuUomodo dilatatum ; umbilicus tertiani 

 diametri partim baud superans. 



Diam. maj. 2, min. h ; alt. i millim. 



This is the smallest member of the group of E. conturta, Fer., hitherto 

 described. The apertural armatui'e is very much alike in E. nuda, E. rinyem, 

 and E. contorta. A similar species, also probably extinct, but with a larger 

 umbilicus, was detected by the Rev. E. ^^^ Thwing, in an extinct crater of 

 the Kona coast ; it is undoubtedly another new species which I propose to 

 name E. ihicinfji, after its discoverer. The present one, which seems to be 

 abundant, is respectfully dedicated to Professor Henshaw, to whom I am 

 much indeted for the whole of the material now considered, and for valuable 

 notes on other Hawaiian shells.
