ACHATINELLA BULIMOIDES. 163 



been taken as the type of fricki, as I have not seen the shelly 

 and the figure is not closely matched among the specimens I 

 have seen. 



A. vidua Pfeiffer, of which the original figure is reproduced, 

 pi. 30, fig. 10, is in my opinion merely a very small or stunted 

 specimen of ovata. Dr. Newcomb, who examined the type in 

 Mus. Cuming, decided it ' ' to be a somewhat worn and faded 

 specimen of this species " (A. ovata). The coloration is ex- 

 actly that of some shells in Gulick's Kahana series, such as pi. 

 33, fig. 2, and pi. 28, fig. Id out of the same lot. Adult shells 

 in this lot of ovata range from 19.3 to 22.8 mm. long. I do 

 not believe that vidua has any racial status. The description 

 follows : " A. vidua Pf r. Shell dextral, subimperforate, conic- 

 ovate, striatulate, under the lens most minutely decussate, 

 glossy ; deep brown, two-banded with white. Spire convexly- 

 conic, the apex somewhat obtuse ; suture nearly simple. 

 Whorls 6, very slightly convex, the last a little shorter than 

 the spire, rounded basally. Aperture a little oblique, trun- 

 cate-oblong; columellar fold obsolete, slightly twisted. Peri- 

 stome strongly labiate, the right margin narrowly reflexed, 

 columellar margin dilated, subadnate. Length 18%, diam. 10 

 mm., aperture 9 mm. long, 4% wide inside " (Pfr.). 



The weakness of the columellar fold, noticed by both Pf eif- 

 fer and Sykes, can be paralleled in the large series of ovata 

 before me. The smallest ovata I have seen is 17% mm. long, 

 dextral, with the pattern of pi. 28, fig. Ic. 



9e. A. BULIMOIDES ROTUNDA Gulick. PI. 28, figs. 3 to 6. 



Very dark chestnut or chocolate, with a white or pale tawny; 

 zone around the upper part of the whorls ; glossy ; suture very 

 distinctly marginate in the last 2% whorls, dark-bordered 

 above and below; apex dark at the tip. Whorls rather swol- 

 len, sinistral. Lip moderately thickened within, but less 

 than in A. ovata,, deep brown. Columellar margin gener- 

 ally less raised outwardly than in ovata, the columellar fold 

 brown or white ; parietal callus a very thin film. 



Length 21, diam. 13 to 13.6 mm. ; 6*4 whorls.
