272 ACHATINELLA LEHUIENSIS. 



striated with growth and transverse lines; white, encircled 

 with a purple-brown streaked zone and two brown zones, one 

 above, the other below the periphery (and sometimes others). 

 Suture submarginate. Whorls 5%, convex. Aperture white ; 

 peristome thin; columellar fold strong, rose colored. Length 

 17, diam. 10 mm.' (Smith). 



Oahu, Waianae range: Lehui [Lihue], on trees (Gulick). 



Achatinella lehuiensis SM., P. Z. S. 1873, p. 76, pi. 9, f. 4. 



The figured type, No. 74 Coll. Boston Society, is here il- 

 lustrated. It resembles A. dimorpha form zonata Gul. rather 

 closely in shape, but the last whorl is slightly more ample ; 

 it is, I believe, more closely related to A. papyracea. There 

 are two deep chocolate bands separated by a white girdle, 

 one immediately above, the other below the periphery. Ad- 

 joining the upper band above there is a zone composed of 

 narrow, brownish vinaceous streaks alternating with narrower 

 whitish ones, and traversed by darker lines near the upper 

 and lower edges. There is a cinnamon line below the white- 

 edged suture, and a small area of the same around the colu- 

 mella ; also a dark line near the lower edge of band iii. The 

 embryonic whorls are white, shading to gray at the tip. The 

 aperture has a white lining and a very slight thickening near 

 the edge, which is beveled and acute, in color light brown, 

 with dark markings where the bands terminate. The colu- 

 mellar fold is quite strong and white. I think the statement 

 "plica columellaris valida, rosea' was due to dirt and the 

 fact that it has a cinnamon border ; but it may possibly have 

 faded. The columellar margin is adnate. 



The suture has a distinct margin defined by an impressed 

 line on the last whorl, but not colored. The shell is moder- 

 ately solid, about as in A. dimorpha. The unique type meas- 

 ures length 16.25, diam. 10 mm., longest axis of aperture 

 8.4 mm. 



T have described the type-specimen in some detail because 

 the species has not to my knowledge been recovered by recent 

 collectors, and its existence in the Waianae range has been 

 doubted I believe unnecessarily. It cannot be expected that 

 further specimens, if found, will agree with the type in all 

 details of color-pattern.
