 Achatinella vittala Reeve, Pilsbry and Cooke, Man. Conch., vol. 22, pp. 289-291,

The lectotype of A. a. globosa (pi. 4, fig. 21) in the British 

 Museum is marked "x" by me and is a deformed specimen. There is a 

 break in the shell at the second embryonic whorl, which accounts for 

 the depressed spire. The last postembryonic whorl is abnormally 

 rounded and enlarged ; postembryonic whorls white lined with cinna- 

 mon buff, peripheral band cinnamon buff, subperipheral band white, 

 basal band hazel. On the aperture side of the last whorl, below the 

 periphery, there is another break in the shell which has been repaired 

 by the animal, and the pattern is lacking on approximately 2 mm. of 

 the shell. The shell is thin, sutural band white ; the lip is Httle thick- 

 ened and colored pale vinaceous drab ; the columella callus white. 

 Length 16.4 mm., greater diameter 12.8 mm., spire height 6.5 mm., 

 number of whorls 5|. 



Specimen A of the type lot (pi. 4, fig. 22) more accurately repre- 

 sents the usual form of A. a. globosa. The postembryonic whorls 

 white lined with pinkish buff, last whorl banded with pinkish buff", 

 axially streaked with white, in the umbilical region a band of cinna- 

 mon buff, darkening near the edge of the lip to mikado brown. 

 Length 16.8 mm., greater diameter 11. 4 mm., number of whorls 6.

A. a. globosa is a distinct subspecies which differs from vittata in 

 being a smaller shell, always dextral and having a different range of 

 color patterns. It occurs mixed with A. a. vittata in the Gulick col- 

 lections, and odd specimens identifiable as globosa are usually found 

 with typical forms of vittata in other collections. 



The type lot of A. a. vittata, consisting of three specimens, has two 

 specimens which are color, patterns of A. a. globosa. One of these 

 marked A (pi. 4, fig. 23) is a light color pattern and a narrow form
