152 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. IO3 



elevation i,ioo feet, 3 dead dextral, Welch, BBM 132771, 1935; also 

 collected by Wilder, BBM 50636, Gulick, ANSP 98628C (figs. 5, 



5a, P- 105)- 



The lightest color pattern found on only two specimens is shown 



on plate 10, figure 29 ; last two postembryonic whorls axially streaked 



with white, neutral gray, and deep neutral gray; impressed sutural 



band and also the subsutural band, which disappears on the last half 



whorl, white axially streaked with seashell pink; lip and columella 



callus light vinaceous fawn. 



A narrow shell (pi. 10, fig. 29a) and a dark color pattern lacks 



the usual white sutural band ; postembryonic whorls chaetura black 



axially streaked with white, or tilleul buff; impressed sutural band 



tilleul buff streaked with avellaneous. Length 20.0 mm., greater 



diameter 12.2 mm., spire height 12. i mm. This form with a colored 



sutural band occurs on five specimens in th^ combined Lemke and 



Welch lots of 45 shells exhibiting the color pattern. Fifty-one percent 



have a white sutural band, the rest a tinted sutural band similar to 



that of figures 29 or 29a. 



ACHATINELLA APEXFULVA SUTURALBA var. i 



Plate 3, Figure 19 



Area 91 ??: Helemano, J. S. Emerson, BBM 102298- 102299, also 

 Gulick. Possibly this race occurred in the South Helemano opposite 

 area 90 in area 91 ?? (fig. 5a, p. 105). No specimens have been found 

 in recent years. 



This variety is similar to A. a. suturalba but has a wider band of 

 white about the suture and never has a dark or a pinkish sutural band 

 similar to that of plate 10, figures 29 and 29a. The usual form (pi. 3, 

 fig. 19) has the embryonic whorls ochraceous tawny; postembryonic 

 whorls pallid neutral gray axially streaked and faintly spirally lined 

 with deep neutral gray, on the last half whorl the streaks are deep 

 purplish gray ; sutural and subsutural bands white ; lip and columella 

 callus tilleul buff. Length 18.8 mm., greater diameter 12.2 mm., 

 spire height 10.6 mm.

 Achatinella apexfulva apicata (Newcomb) Pfeiffer, Pilsbry and Cooke, Man. 

 Conch., vol. 22, pp 324, 325, 328, pi. 60, figs. 4a, 4c (only), 1914. 



There are two specimens of A. a. apicata in the type lot. One of 

 them marked "A" by me (pi. 11, fig. 2) is considered the lectotype.
