ACHATINELLA PULGENS. 201 



with the descriptions of Mr. Gulick 's lettered varieties. Those 

 who have not access to the original publication can find them 

 in Mr. Thwing's Reprint, pp. 40, 41. Data so presented serve 

 to show the wide range of variation, but are not otherwise 

 available as variation is now studied. 



The few Kailua specimens we have seen seem to be at 

 least as near phceozona as plumata, although Gulick classed 

 them with the latter. They have the convex-sided spire of 

 phczozona. 



" Achatinella diver sa Gulick. Shell sinistral, very rarely 

 dextral, imperforate, ovately or elongately conic, solid, shin- 

 ing, striated, white or variously painted with yellow or green ; 

 apex subacute ; spire conic ; suture marginate, moderately im- 

 pressed; whorls 6%, somewhat convex; columellar fold cen- 

 tral, strong, rose or white ; aperture oblique, truncately auri-

 gin dilated, adnate; parietal margin wanting. Length 21, 

 breadth 11%, length of body whorl 15%, length of aperture

 Niu, Oahu, J. T. G.!" 



* * Var. a. Pure white, except the columella, which is fre- 

 quently lilac or rose. Var. b white with one black band. 

 Var. c white with two black bands, one entering the aper- 

 ture; approaches A. fulgens Newc. Var. d white with yel- 

 low or green base. Var. e yellow with white bands. Var. f 

 yellow, fading towards the apex. Var. h green, passing 

 into gray or brown towards the apex. Var. i green with 

 white bands. 



"Remarks: Differs from A. plumata nob. in the character 

 and arrangement of its colors, and from A. fulgens Newc. in 

 the absence of the white sutural band and the two broad black 

 central bands which characterize that species. 



"The specimens found in Niu do not present the green 

 varieties, but incline more to white, and are also thicker and 

 more ovate in form than those found in Palolo. The average 

 weight of full grown specimens from Niu is about 9 grains, 

 that of the Palolo specimens is 7.2 grains. 



"I have six or eight dextral specimens belonging to varie- 

 ties d, e, g and i" (Gulick).
