ACHATINELLA THAAMUNI. 273 



The locality "Lehui' (more properly Lihue) was used by 

 Gulick in rather a wide sense, I suppose covering much of the 

 country south of Popouwela, towards Palikea, on the eastern 

 slope of the range. As the form is probably very local, there 

 is hope that it may still be found. 



While somewhat resembling A. dimorpha form zonata Gul., 

 it seems to me to be distinct from that, and from A. papyracea. 

 It is certainly quite distinct from A. casta. 



29a. A. LEHUIENSIS GULICKIANA ii. subsp. PL 42, fig. 4. 



The shell is more conic than lehuiensis, in shape resembling 

 the shorter forms of A. dimorpha form zonata ; solid ; white, 

 with a narrow chestnut band just above the periphery, ap- 

 pearing above the suture, and a broad one occupying most of 

 the base ; a short distance below the suture an ochraceous band 

 revolves. Embryonic whorls white. Aperture and colu- 

 mellar fold white ; the outer lip not thickened, stained brown 

 at the terminations of the bands. Length 15.75, diam. 10, 

 length of aperture 8.1 mm. ; 5% whorls. 



Oahu, Waianae range: Mokuleia, Gulick coll., No. 1471 coll. 

 Boston Society. 



The type is a single specimen in the Gulick collection. If 

 it is really from Mokuleia, it may be a distinct species. 

 Moreover, I cannot connect it with any form of the Main 

 Range. It is not, in my opinion, to be referred to zonata 

 Gulick. It cannot be connected with A. thaanumi, which has 

 a more elliptical shape. In texture and weight A. gulickiana 

 agrees with lehuiensis. Except in the structure of the lip it 

 has some resemblance to A. fuscobasis. 



We would not describe a subspecies from one specimen if it 

 were not important to direct attention to the existence of a 

 member of this group near the western end of the Waianae 

 range. 



30. A. THAAMUNI P. & C., n. sp. PL 42, figs. 5, 6. 



The shell is perforate, sinistral, ovate-conic, thin but mod- 

 erately strong; white, encircled by two chocolate bands, one 

 above, the other below the periphery; no subsutural band or
