ACHATINELLA SWIPTII. 309 



Specimens are figured from Kalaikoa valley, from the Gu- 

 lick collection, pi. 58, fig. 7, and figs. 13, 13a, 136. These last 

 were regarded by Mr. Gulick as a form intermediate between 

 gulickii and flavida, but they seem to me rather swiftii-flavida. 

 PL 59, figs. 1, la, 16, selected from Gulick 's Ahoriui lot, 

 further illustrate the decadence of streaks. 



The descriptions of forms considered synonyms of swiftii 

 here follow, together with notes on the types and other speci- 

 mens. 



"Apex albospira Sm. (pi. 59, fig. 3, type specimen, no. 96 

 Bost. Soc.) Shell dextral, subperf orate, shortly ovate-conic, 

 little shining, striated with growth-lines but hardly spirally; 

 white, a zone above the periphery and the base livid brown; 

 suture lightly margined; whorls 6, the first four a little con- 

 vex, the rest convex; aperture white; peristome thickened 

 within; columellar fold strong, white, reflexed, nearly cover- 

 ing the small crevice. Length 17, diam. 10. 



' ' Var. : Shell white, ornamented above with a few yellow 

 zones and yellow towards the base, encircled with a few darker 

 zones. 



"Reported to be from Ewa, on Oahu 7 (Smith). 



The type specimen is an unique, no. 96 of the Gulick type 

 collection, Boston Soc. N. H. The apex and whole embryonic 

 shell are pure white. A band appears just prior to the begin- 

 ning of the penult, whorl. On the last whorl the band and the 

 whole base are vinaceous drab, lightly streaked with white. 

 Aperture and peristome white. Length 16.2, diam. 10.2 nun. 

 It was probably somewhat dwarfed by misfortune, as there 

 was a break in the fourth whorl, and another, affecting the 

 whole lip, about 4 mm. behind the final peristome. Some of 

 Gulick 's polymorpha have the same color-pattern, but with a 

 dusky apical tip. However, in some other patterns of poly- 

 morpha the tip is quite white. There can be no doubt that 

 albospira is merely a form of "polymorpha 7 or possibly 

 "flavida" the exact name is not significant, since these Gu- 

 lickian forms are not real races. 



"Apex innotabilis Sm. (pi. 59, fig. 7, photographic repro- 

 duction of original figure). Shell sinistral, subperf orate,
