ACHATINELLA APEXFULVA BRUNEOLA var. i 

 Plate i, Figure 33; Plate 5, Figure 18 



Area 29: Kalauao-Hanaiki Ridge, locality 183, elevation 1,300- 

 1,350 feet, Meinecke, 13 sinistral 1935; 183?, Meinecke, 1913 (figs. 4, 



4(h p. 53)- 



The usual form of the shell is larger than typical A. a. hruncola, 

 the mean length 20 + mm, instead of 19 + mm. The color pattern 

 differs from typical bnmcola by having the base banded with yellow ; 

 the shells are usually sinistral. The form is an intermediate one be- 

 tween the higher race of A. a. aureola and A. a. hriineola. 



The usual form and color pattern of the shell (pi. i, fig. 33) has 

 the embryonic whorls white or pale pinkish buff, last two postembry- 

 onic whorls amber brown, peripheral band and base light cadmium, 

 subperipheral band chestnut, below which are lines of amber brown 

 and a band about the umbilicus of a deep shade of mars brown, 

 behind the edge of the lip last whorl tinted with a streak of chestnut. 

 Length 20.4 mm., greater diameter 13. i mm., spire height 10.7 mm., 

 number of whorls 6|. The color of a dextral shell (pi. 5, fig. 18) 

 shows the light color pattern of the shell ; postembryonic whorls mars 

 yellow or a light shade of sudan brown, base cadmium with a sub- 

 peripheral band of chestnut. 



ACHATINELLA APEXFULVA BRUNEOLA var. 2 



Plate i, Figure 30; Plate s, Figures 15-16 



Achatinclla turgida ovum Pfeiffer, Pilsbry and Cooke, Man. Conch., vol. 22, 

 p. 298, pi. 56, figs. 7-7d (not from Moanalua but from Aiea, according to 

 Dr. Cooke) and figure 6 (only), 1914 (figure 6 also matches color patterns 

 of A. a. ovum var. 2). 



Area 25: Aiea-Kalauao Ridge, locality 170C-6*, elevation 1,550- 

 1,800 feet, Lemke, 1924 and 1932 (figs. 4, 4a, p. 53) ; also collected 

 in Aiea by Cooke, BBM 72501-72512, BBM 72514, BBM 16346- 

 16347, A. F. Judd, BBM 110211-110224, Wilder, BBM 50528, 15 

 sinistral. 



The main difference between the shells of area 25 and typical 

 bnmcola is that the dominant color pattern is a yellow-lined form in- 

 stead of the darker usual hruncola pattern of plate 5, figure 17. The 

 yellow shells are rare in area 28, whereas in area 25, 21 percent have 

 a definitely yellow pattern without strong brown bands (pi. 5, fig. 15). 



The usual form and color pattern of 37 percent of the shells (pi. i, 

 fig. 30) has the embryonic whorls white; first quarter postembryonic 

 whorl white, next quarter tawny lined with pale pinkish buff", penulti-
