Newcomb's description of A. a. turgida may refer to either of his 

 original figures. I shall choose his figure lo (pi. 6, fig. 2) to be the 

 lectotype, because it has the most usual pattern. The original speci- 

 men (pi. 6, fig. 3) of Newcomb's figure 10 has white embryonic 

 whorls ; penultimate and last postembryonic whorls pallid mouse gray, 

 axially spotted and spirally banded with hessian brown, on the last 

 whorl near the middle of the whorl there are three axial bands of 

 cinnamon, behind the edge of the lip an axial band of hessian brown, 

 in the umbilical region below the last hessian brown band the ground 

 is cream bufif, mixed with pallid mouse gray ; impressed sutural band 

 hessian brown ; lip and columella callus light vinaceous fawn. Length 

 19.7 mm., greater diameter 13.4 mm., spire height 10.9 mm., number 

 of whorls 6^. 



Distribution, area 35 : Waiau-South Waimano Ridge, locality 

 200B*, elevation 850-1,000 feet, 7 dextral, i sinistral 1929; 202B, ele- 

 vation 1,000-1,150 feet, 1913, I dextral, 8 sinistral 1914, 1920, 7 dex- 

 tral, 2 sinistral 1929, 12 dextral, i sinistral 1932, 1934; 202BB*, 

 elevation 1,050-1,150 feet, 5 dextral, i sinistral 1929, all collected by 

 Meinecke. Waimano, Wilder, BBM 50598 ; Waimalu, J. S. Emer- 

 son, BBM 102218. Pilsbry and Cooke report A. a. turgida to have 

 been taken in Waiawa by I. Spalding. This is an error, for no A. a. 

 turgida are found except in the region of Waimalu to Waimano 

 (figs. 4, 4a, p. 53). Holotype in BM marked with an x. 



The usual form and color pattern (pi. i, fig. 41) of A. a. turgida 

 in area 35 is very much like the lectotype in color. The shell measures : 

 Length 19.0 mm., greater diameter 13.2 mm., spire height lo.i mm., 

 number of whorls 6|. The embryonic whorls are white ; postem- 

 bryonic whorls diamine brown, splotched and banded with broken 

 bands of pale smoke gray tinted with chamois; impressed sutural 

 band diamine brown; lip and columella callus pale vinaceous fawn. 



The darkest or reddish-brown color pattern and narrow form of the 

 shell (pi. 6, fig. 4) has the postembryonic whorls diamine brown and 

 looks like a sinistral specimen of A. a. apexfulva which has white 

 embryonic whorls instead of yellow ones. Length 19.5 mm., greater 

 diameter 12.6 mm., spire height lO.o mm.
