130 ACHATINELLA T^NIOLATA. 



The same variety occurs in Wailupe and Waialae valleys. A 

 series is figured, pi. 25, figs. 5 to 5d, Waialae ; also pi. 25, fig. 

 6, a clear green shell occurring with the brown-streaked form, 

 Wailupe. Some shells from Waialae have spiral bands as in 

 var. rutila (pi. 25, figs. 7 to 76). 



Gulick found a few subvirens also in Palolo, the white, 

 green-streaked and brown-streaked forms. Also specimens 

 connecting with form rutila, the sutural border yellow in 

 some, white in other examples. Color yellow with indistinct 

 olive lines, bandless or with white or chestnut bands (pi. 25, 

 25, figs. 9, 9a, 96, Palolo) . 



3. A. T^CNIOLATA Pf eiffer. PI. 24, figs. 14 to 19 ; pi. 25, figs. 

 13 to 13c. 



" Shell ovate-oblong, solid, striatulate, glossy; white orna- 

 mented with varying brown bands, more obsolete above. Spire 

 conic, rather acute. Whorls 6, slightly convex ; the last about 

 four-ninths the length. Columella white, strongly tooth- 

 folded above. Aperture irregularly semi oval, white within, 

 glossy; peristome very narrowly thickened outside, strongly 

 lipped within, the columellar margin dilated, reflexed, ap- 

 pressed. Length 20, diam. in the middle 11 mm. ; aperture 

 10x4!/2 mm. Sandwich Is., Mus. Cuming.' (P/V.) 



Oahu : Palolo to Keawaawa, and northward across the range

A. taniolata typically has a white ground, variously banded 

 or streaked with rufous or ochraceous-orange, or without 

 markings. The contour is usually somewhat more capacious 

 and the surface smoother than in the forms subvirens and 

 rutila of A. viridans; but both contours and sculpture inter- 

 grade in some shells. The coloration is characteristic in typi- 

 cal examples, but here again there are colonies from Palolo, 

 AVaialae, Keawaawa and elsewhere, which could be placed,
