Original Descriptions of Achatinella. 21 



Shell sinistral (sometimes dextral), globoseh' conical, shining, 

 striated obliquely with lines of growth (not spiral), brown, striped 

 with light brown, indistinctly encircled with many whitish spiral 

 lines ; suture richly margined with brown ; spire slightly concave; 

 whorls 61-2, first 31-2 somewhat convex, whitish, others convex ; 

 aperture receding, white ; perist. slightly dilated and thickened 

 within, with the margin tinged with pale rose (or brown); colu- 

 mellar fold strong.

 mano. — Gk. 



18. Achatinella neglecta vSmith. 



Apix iii'iih-diii Sin. P. Zool. Soc. London. 1S73, p. 78; pi. i.x, fig. 22. 



Testa vel sinistrorsa vel dextrorsa, impcrforata, globoso-couica, incre- 

 inenti lineis leviter striata, dilute brunnea, saturatius vel cinereo strigata ; 

 regio umbilicalis sttpe castanea ; apex albiis ; spira coiicaviuscula ; aiifract. 

 6, primi 4 planiusculi, cteteri convexi ; siitura saturate castaneo distincte niar- 

 ginata ; apertura intus albida ; perist. fuscescens, intus incrassatuni ; plica 

 columellaris valida, rubescens. Long. 17. diam. 11 1-2 mill. 



Shell sinistral or dextral, imperforate, globosely conical, finely 

 striated with lines of growth, pale brown .striped with deeper brown 

 or gray ; often che.stnut near the umbilicus ; apex white ; spire 

 somewhat concave ; whorls 6, first 4 more or less flat, the others 

 convex ; suture distincflly margined with deep chestnut : aperture 

 whitish within ; lip brownish, thickened within ; columellar fold 

 strong, reddish. 



In form this species agrees very fairly with some varieties of 

 lugubris Chem.; but it has shorter spire and blunter apex than the 

 usual form of that species. The coloration is of a different char- 

 acter. — Sm. 



Hab. Wahiawa. 



Dr. Cooke found that, in the type examples, the dark suture 

 and the characteristic bands would seem to place this shell in 

 the forbcsiana group.
