ACHATINELLA APEXFULVA FLAVIDA Gulick 



Plate 10, Figures 17-20 



Apex flavidus Gulick, Proc. Zool. Soc. London, 1873, p. 80, pi. 10, figs, i, la. 

 Achatinella swijtii Newcomb, Pilsbry and Cooke, Man. Conch., vol. 22, pp. 306, 

 311, 312, 315, pi. 58, figs. 10, 12-12& (only), 1914. 



The subspecies is characterized by having a light yellow color pat- 

 tern. The form of the shell resembles A. a. gulickii var, 2. The 

 holotype is a rare color pattern and not characteristic of the sub- 

 species. The holotype of A. a. flavida (pi. 10, fig. 17) has the first 

 embryonic whorls a very dilute shade of pale ecru drab, fading to 

 white ; postembryonic whorls white, first postembryonic whorl with 

 a cinnamon-buff supraperipheral line which widens on the last two 

 whorls to a band of mikado brown or walnut brown ; the impressed 

 sutural band white on the first embryonic whorl, on the last two 

 whorls mikado brown darkening to cacao brown, base cartridge buff ; 

 columella callus pale pinkish cinnamon ; lip cartridge buff. Length 

 19.8 mm., greater diameter 12.8 mm., spire height 10.7 mm., number 

 of whorls 6|. 



Distribution, area?: Type locality Kalaikoa, Gulick (probably 

 somewhere in South Kaukonahua Stream at a low elevation). Also 

 Ahonui, Gulick, which is probably erroneous if Kalaikoa is correct, 

 because the type locality was probably of limited extent. 



GuUck's var. a (pi. 10, fig. 18) has a more usual color pattern; first 

 embryonic whorl and a half white, shading to cream buff on the later 

 embryonic whorls ; first two postembryonic whorls pinkish buff 

 axially streaked with cinnamon buff and mikado brown ; below the 

 impressed sutural band of tawny, which darkens on the last two 

 whorls and a half to orange cinnamon, there is a band of white; on 

 the penultimate whorl there is another band of white just above the 

 edge of the periphery, last whorl chamois spirally banded with sayal 

 brown. Length 17.6 mm., greater diameter 12.2 mm., spire height 

 9.3 mm., number of whorls 6. This color pattern occurs on 34 percent 

 of the combined Kalaikoa and Ahonui lots, all but 7 of which are from 

 Kalaikoa. 



The usual color pattern in the Bishop Museum lots of the Gulick 

 collection (pi. 10, fig. 19) has the embryonic whorls white, post-
