42 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. IO3 



The shell may lack the dark chocolate Ijands (pi. 5, fig. 5) and have 

 the last two postembryonic whorls white, lined with pinkish buff 

 above the periphery, at and below the periphery with sayal brown, 

 base tinted with cream color. The postembryonic whorls may be 

 almost entirely white (pi. 5, fig. 5a) except for a patch of sayal brown 

 on the impressed sutural band on the first and fourth postembryonic 

 whorl, and a band and a line of ochraceous tawny on the base. A 

 yellowish pattern (pi. 5, fig. 5&) is very much like the yellowish pat- 

 tern of A. a. simidans (pi. 4, fig. 35a), and also that of A. a. rubidi- 

 picfa (pi. 5, fig. 2d), postembryonic whorls pinkish buff, lined and 

 banded with ochraceous tawny and tawny, about the periphery and 

 below the ground is white, banded below the periphery with russet 

 deepening to chocolate on the last half whorl. 



This race has been considered a variety of A. a. simidans because 

 of its small size and similarity in form. In a fossil bed, locality 150B-2, 

 a few specimens of apexfidva are found and may be considered 

 the extreme limit of this race of- simidans var. 2, although it is prob- 

 able that, were there more specimens obtainable retaining a sufficient 

 amount of the color pattern, it might prove to be another variety.

Plate i, Figure 13; Plate 4, Figures 17-20^; 



Achaiinella mttafa Reeve, Conch. Icon., vol. 6, pi. 2, fig. 9, April 1850. — Pilsbry 

 and Cooke, Man. Conch., vol. 22, p. 289, pi. 57, figs, i, 2, 2a, 2c (only), 1914. 



The holotype of A. a. vittata in the British Museum has a spot 

 of red sealing wax on the aperture side of the shell (pi. 4, fig. 17). 

 Postembryonic whorls white, penultimate banded wnth avellaneous, 

 last whorl above the periphery with two bands of avellaneous and 

 a subperipheral band of pinkish buff, below the periphery banded and 

 lined with fawn color, and a band of army brown in the umbilical 

 region; lip and columella callus pale vinaceous fawn. Length 19.0 

 mm., greater diameter 12.7 mm., spire height lo.o mm., number of 

 whorls 6. 



Distribution, area 12: Nuuanu, Gulick; Hillerbrand's Glen, 

 Nuuanu, locality looE-i*, elevation 1,000-1,500 feet, R. A. Cooke, 

 BBM 58284, and C. M. Cooke, BBM 22119, 19916 (figs. 3, 3a, p. 29). 

 Dr. C. M. Cooke tells me that these shells come from somewhere along 

 the ridge on which locality lOoE-i* is plotted. They were probably 

 collected on the lower portion of the ridge at an elevation of around 

 1,000-1,500 feet, because IMeinecke reports the larger race of A. a.
