104 CARELIA.

 azona ANCEY, Proc. Malac. Soc. vi, p. 121 (1904). Carelia

The summit is rather pointed, the first 3 whorls being 

 straight-sided, subsequent whorls are slightly convex, and last 

 whorl is somewhat cylindric, being flattened in the middle, 

 convex or subangular above, and angular at the periphery, 

 below which it tapers straightly to the base. Apical sculpture 

 as in the other species; the spiral sculpture begins on the 

 fourth whorl as spiral series of long granules. On the last 

 3 or 4 whorls there are several low, cord-like spirals, more or 

 less knotted by coarse, irregular, longitudinal growth-folds. 

 This sculpture varies from strong to subobsolete in different 

 specimens, and is wanting on the base. There is also a very 

 dense, fine, wavy microscopic spiral striation, visible in the 

 most perfect shells, but readily worn off. 



The color varies from rather bright yellow to dark chest- 

 nut, the base being darker, of a chocolate shade. In the 

 color-form newcombi there is a pale belt below the periphery. 



Mr. Ancey's var. azona is identical with the typical 

 C. turricula.

Chestnut-colored with a pale yellow belt below the peri- 

 pheral angle, the base black. Length 71, diam. 19, aperture 

 21 mm. (Pfr.). This color form differs from the type only 

 in the conspicuous yellow belt bounding the chocolate basal 

 area. Sometimes the upper surface is yellow with an orange- 

 brown tint, darker than the belt (fig. 4). The spiral sculp- 

 ture varies in prominence among individuals of the same lot. 

 In some shells the spirals are very conspicuous (figs. 4, 5), 

 in others almost obsolete.

The last 3 or 4 whorls have coarse, irregular ivrinkles of 

 grotvth and several coarse, low spiral cords, often more con- 

 spicuous than in the typical turricula. They are dull brown,
