128 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. IO3 



lined with white or tillcul buff and axially streaked with benzo brown, 

 peripheral band white; lip and coluinella callus light pinkish cinnamon. 



Mixed with other lots of shells of various subspecies from Ahonui, 

 Kalaikoa, and Wahiawa, a group of distinct color patterns occur which 

 resemble A. a. conifonnis. All shells similar to coniformis are mark- 

 edly ornamented with fine spiral lines and weakly streaked with fine 

 axial streaks. These forms (pi. 2, fig. 34; pi, 9, figs. 20, 20a) prob- 

 ably came from a single locality or from the same general area as the 

 holotype of A. a. coniformis. The holotype is probably a rare color 

 pattern of the subspecies. 



In the usual form and color pattern (pi. 2, fig. 34) of A. a. 

 coniformis the embryonic whorls shade from white to light buff; 

 first three-fourths postembryonic whorl white axially streaked with 

 brownish drab, next whorl and a fourth dark gray axially streaked 

 and faintly spirally lined with white, last whorl light drab, shading to 

 snuff brown on the last fourth whorl, axially streaked and spirally 

 lined with white ; impressed sutural band on the first postembryonic 

 whorl the same as on the rest of the whorl, on the remaining whorls 

 white ; lip not completely thickened, color avellaneous ; columella callus 

 white tinted with pale vinaceous fawn. Length 17.8 mm., greater 

 diameter 12.5 mm., spire height 9.8 mm., number of whorls 6^. 



The color pattern may be more brownish (pi. 9, fig. 20) and the 

 form more elongate than the usual form ; embryonic whorls white ; 

 first postembryonic whorls, up to the last whorl, tilleul buff axially 

 streaked with pallid mouse gray, last whorl a yellowish hue of vina- 

 ceous buff spirally lined with white ; impressed sutural band same as 

 rest of whorl ; lip light vinaceous fawn. Length 18.3 mm., greater 

 diameter 11. 7 mm., spire height 9.4 mm. An obese and strongly 

 lineate form (pi. 9, fig. 20fl) has the first two embryonic whorls 

 white, last embryonic whorl cream color; first postembryonic whorl 

 vinaceous drab, lined with white, penultimate whorl light drab spirally 

 lined and axially streaked with white, last whorl drab spirally banded 

 above the periphery with a band of white which is lined with four 

 lines of drab, below the periphery ground lined and streaked with 

 white ; lip and columella callus light vinaceous fawn. Length 17.4 mm., 

 greater diameter 13.2 mm., spire height 9.4 mm.

The shell is usually sinistral and resembles the form of A. a. 

 versicolor, but differs from A. a. versicolor by lacking a white periph-
