338 ACHATINELLA VALIDA. 



It happened that the same streaked pattern of what seems 

 to have been a common Waialee shell served as the types of 

 cinerosa and leucozonus, so that the two names are exactly 

 synonymous. The original description of leucozonus follows. 

 The original figure is like my pi. 55, fig. 12. 



"Apex leucozonus Gulick. Shell subperf orate, dextral, glo- 

 bose-conic, glossy, striated with incremental (but scarcely 

 spiral) lines; gray-brown, streaked with deep gray-brown, at 

 the periphery interrupted by a white zone ; suture distinctly 

 margined with white. Spire straightly conic. Whorls 6, the 

 first three a little convex, the rest convex. Aperture white; 

 peristome a little dilated, tinted with pale rose-brown, thick- 

 ened within ; columellar fold strong, white. Length 19, diam. 

 12 mm. 



"The metropolis of this species is Waialei. A few speci- 

 mens have also been found in Wahiawa, Island of Oahu. It is 

 related to and passes into A. napus Pfr., which is also found 

 in Waialei ; but the usual forms are distinguished by having a 

 shorter spire and a white suture, and in being free from the 

 yellowish hue of that species. This species is always dextral. 

 The specimen figured is from Waialei' (Gulick). 



A rather peculiar form of cinerosa (pi. 55, figs. 17, 18) was 

 noticed by Mr. Gulick under his description of A. leucorraphe : 

 "a variety with spire regularly conical is reported to have 

 been found in Waimea.' This shell is certainly a form of 

 cinerosa (leucozona), and not of leucorraphe. The embryo is 

 shaped like that of valida, ivory or buff with a fleshy tip ; last 

 whorl light pinkish cinnamon to pallid purplish gray, nar- 

 rowly and closely streaked with brownish or slaty shades, usu- 

 ally with a few inconspicuous dark lines around the base. The 

 suture has a wide white border, but there is no peripheral 

 band. Lip white. All of a series of 21 are dextral. The local- 

 ity Waimea is marked with a query in Mr. Gulick 's collection, 

 but no doubt the form came from somewhere in the northwest, 

 and may have been from Waimea.
