NO. I ACHATINELLA APEXFULVA DIXON — WELCH 35 



are streaked with white, in the umbih'cal region a band of naples 

 yellow; lip and columella callus light vinaceous fawn. Length 

 17.0 mm., greater diameter 11.8 mm., spire height 9.2 mm., number 

 of whorls 6. 



ACHATINELLA APEXFULVA BUENA, new subspecies 

 Plate i, Figure 8; Plate 4, Figures 14, 14(7 



The shell is small, sinistral, and seems to be closest in form to 

 A. a. s'unulaior but may be a race which occurred near A. a. hanleyana. 

 The yellow-banded embryonic whorls are different from anything 

 known from the region of Wailupe to KaHhi Valleys. However, be- 

 cause of the darkened embryonic whorls and the small size of the 

 shells, this distinct color form is placed under the subspecific group 

 of A. a. ce^tiis. The first embryonic whorl of the holotype (pi. i, 

 fig. 8) is army brown, next whorl, upper eighth white, lower seven- 

 eighths shades from avellaneous to chamois, last embryonic whorl, 

 upper half white, lower half chamois ; postembryonic whorls white 

 banded just above the edge of the periphery with a band of russet 

 flecked with light buff, on last whorl supraperipheral band not so 

 intense, having more streaks and flecks of light buff in it, peripheral 

 band white except for a line of tawny on the lower portion of the 

 band, base tawny axially streaked with light buff', with a line of 

 white and a band of cream color in the umbilical region; lip and 

 columella callus vinaceous buff*. Length 16.4 mm., greater diameter 

 10.6 mm., spire height 8.8 mm., number of whorls 5f . 



This subspecies has been named after Buena Blok, the wife of 

 Arthur Blok, of London, an ardent student of conchology.

This form appears in the Gulick collection in several lots. In one 

 lot from Palolo one specimen is found mixed with A. a. simidator. 

 Gulick has another lot labeled Waipio BBM 70382, and still another 

 Kalaikoa BBM 106736. It is probable that the Emerson and Gulick 

 shells all came from a single now extinct lowland locality, but the 

 exact location is not known. Another specimen was obtained from 

 A. Block, BBM 165793, and one from Sowerby and Fulton, BBM 

 165794. 



A narrow specimen (pi. 4, fig. 14) measures: Length 16.6 mm., 

 greater diameter 10. o mm., spire height 8.9 mm. ; the postembryonic 

 whorls are more heavily banded than the type, the bands are wood 

 brown flecked with vinaceous buff. A light color form (pi. 4, fig. 14a)
