54 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. IO3 



Distribution probably somewhere in the region of area 26?: Aiea- 

 Kalauao Ridge, approximate locality 170-1?, Judd, BBM 110210, 

 and Cooke, BBM 72494 (figs. 4, 4a, p. 53). The subspecies is named 

 after Dr. Henry A. Pilsbry. The shell has not been found in many 

 years and may be extinct. 



The form of a broadly banded juvenile shell (pi. 5, fig. 27) has 

 an elongate spire. Length 16.9 mm., greater diameter 11. 6 mm., 

 spire height 9.0 mm. Postembryonic whorls white, banded with 

 cinnamon, last whorl below the periphery cinnamon, lined with two 

 lines of white and a line of mikado brown. The shell is a dead speci- 

 men and the color has faded. 



ACHATINELLA APEXFULVA ROSEATA, new subspecies 



Plate i, Figure 39; Plate 6, Figures 25-256 



The shell is a small fossil form which looks like A. a. lilacea from 

 the region of North Kaukonahua Stream. The holotype (pi. i, fig. 39) 

 has white, pointed, embryonic whorls; postembryonic whorls pale 

 vinaceous fawn axially streaked and faintly spirally lined with light 

 vinaceous fawn and vinaceous fawn; impressed sutural band white 

 or tinted pale pinkish buff; lip outer margin pinkish buff, inner 

 margin pale pinkish butf. Length 17.5 mm., greater diameter 

 1 1.5 mm., spire height 9.6 mm., number of whorls 6-2. 



Distribution, area 37?: Waimano Stream. "Just below the bridge 

 on the plantation R. R.," C. M. Cooke, BBM 40679-40680, also col- 

 lected by Thaanum, BBM 40716-40717, and Wilder, BBM 51932. 

 The shells were found in fossil state under a boulder in the bottom 

 of the gulch. I have tentatively plotted the locality somewhere in the 

 region of area 37? (fig. 4a, p. 53). 



The holotype is a little smaller than usual. The usual form should 

 be i8-fmm., with a greater diameter of ii-j-mm., but no specimens 

 with the usual form have the color sufficiently well preserved to be 

 used for the holotype. The darkest color pattern (pi. 6, fig. 25) on a 

 single specimen has the postembryonic whorls colored light vinaceous 

 fawn axially streaked and lined with vinaceous fawn; impressed 

 sutural band vinaceous buff; lip vinaceous buft". Length 19. i mm., 

 greater diameter 11.9 mm., spire height 11.2 mm. 



The narrowest specimen (pi. 6, fig. 25a) measures: Length 

 18.1 mm., greater diameter 10.8 mm., spire height ii.o mm. The 

 typical sinistral form of the shell (pi. 6, fig. 25^) measures: Length 

 18.0 mm., greater diameter 11. 7 mm., spire height 10.4 mm.
