94 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. IO3 



whorl pinkish buff spirally lined with light drab, last half pale mouse 

 gray, lined and streaked with light buff, last whorl below the im- 

 pressed sutural band light buff, banded or lined with drab and 

 cinnamon buff, just above and below the white peripheral band are 

 two bands of smoke gray, which shade to wood brown on the last 

 half whorl, base white faintly lined with smoke gray; impressed 

 sutural band amber brown shading to tawny on the last whorl; lip 

 and columella callus pale vinaceous pink. Length 18.0 mm., greater 

 diameter 12.2 mm., spire height lo.o mm., number of whorls 6. 



Five sinistrals are found in lot BBM 102247 of 23 shells. The 

 color pattern on a few shells differs from the usual one. The post- 

 embryonic whorls may be white or pale pinkish buff (pi. 8, fig. 29a), 

 lined on the first and penultimate whorls with fawn color or wood 

 brown, last whorl banded at the edge of the periphery with fawn 

 color, banded below the periphery with benzo brown axially streaked 

 with pale pinkish buff. 



ACHATINELLA APEXFULVA FLAVITINCTA, new subspecies 



Plate 2, Figure 7 ; Plate 8, Figures 30-30^ 



The form is closely related to A. a. polyniorpha but dift'ers in having 

 the last whorl lined with dark lines of reddish brown. Plate 8, 

 figure 30c, looks like Smith's Apex neglectus (pi. 8, fig. 24), except 

 for the embryonic whorls and the lined last half postembryonic 

 whorl. 



The holotype (pi. 2, fig. 7) has the embryonic whorls bicolored, first 

 embryonic whorl upper half white, lower half walnut brown, remain- 

 ing embryonic whorls white ; first postembryonic whorl white, penulti- 

 mate whorl white with a faint line of light olive gray on the lower 

 half of the whorl, last whorl above the periphery white, finely lined, 

 axially streaked or tinted with chamois and banded above the edge of 

 the periphery with olive buff, below the periphery banded or tinted 

 with pallid mouse gray and lined with line and a band of benzo 

 brown or fuscous; impressed sutural band army brown on the first 

 whorl, on the penultimate avellaneous, on the last whorl ochraceous 

 tawny; lip light vinaceous fawn. Length 17.2 mm., greater diameter 

 II. 3 mm., spire height 9.5 mm., number of whorls 6.
