also shows a great range. All the shells of area 47, however, are 

 reddish-brown lined or banded shells, and the ground color is usually 

 pure white. The shells are the next race occurring above A. a. 

 simulacrum. 



In locality 219B the usual form of the shell (pi, 7, fig. 16) has the 

 postembryonic whorls white tinted on the last whorl with pinkish buff, 

 banded on the last two whorls with chocolate. Length 19. i mm., 

 greater diameter 13.3 mm., spire height 9.5 mm. An obese specimen 

 (pi. 7, fig. i6a) measures : Length 20.5 mm., greater diameter 

 14.0 mm., spire height 10.9 mm. It has the lightest color pattern, which 

 is white lined with chocolate and tawny. 



The region of locality 220A ? has dark banded forms such as plate 7, 

 figures 17 and 17a, which are banded or lined with chocolate, or light 

 forms which are banded and lined with kaiser brown (pi. 7, figs. 

 lyb, 17c). The extreme obese form (pi. 7, fig. 17) measures: Length 



20.6 mm., greater diameter 14.2 mm., spire height 9.7 mm. A narrow 

 shell, figure lyb, measures: Length 19.1 mm., greater diameter 



12.7 mm., spire height 10.2 mm. 



ACHATINELLA APEXFULVA CHROMATACME Pilsbry and Cooke 



Plate i, Figure 53; Plate 6, Figures 20-236 



Achatinella swiftii chromatacme Pilsbry and Cooke, Man. Conch., vol. 22, 

 p. 316, pi. 59, figs. 5-5^ 1914- 



The subspecies A. a. chromatacme is closely related to A. a. per- 

 plexa, differing mainly in having dark-colored embryonic whorls, tan 

 or yellowish-brown color patterns that do not occur in area 40, and 

 the usual form having a wide Hght-colored band at the edge of the 

 periphery. In rare cases the embryonic whorls may be white (pi. 6, 

 fig. 22a), and the shell looks very much like a form of A, a. perplexa. 



The shell of plate 59, figure 5, of the Manual of Conchology is 

 selected by Pilsbry and myself for the lectotype of A. a. chromatacme 

 and is reproduced in this paper on plate 6, figure 20. The first em- 

 bryonic whorl of the lectotype is pinkish buff shading on the next 

 whorl to cinnamon, which lightens on the upper half of the last 

 embryonic whorl to pinkish buff; first postembryonic whorl, upper 

 half pinkish buff lined with sayal brown, lower half sayal brown, 

 penultimate whorl, upper half pinkish buff, lower half ecru drab 

 axially streaked with rood's brown, last whorl above the white periph- 

 eral band vandyke brown darkening to bister, axially streaked with 

 ecru drab, below the periphery warm sepia axially streaked with 

 chocolate ; impressed sutural band pinkish buff ; lip margin army
