3 sinistral; 240L-4, elevation 1,750 feet, all Meinecke-coUected, 1933 

 (figs. 5, 5a, p. 105). 



The typical color pattern occurs on 40 percent of the shells in area 

 56. Thirty-three percent have a reddish-brown banded color pattern 

 (pi. 7, fig. 24a), which has the postembryonic whorls white, lined 

 with hay's maroon; impressed sutural band russet. Half of these 

 reddish-brown banded shells are similar to plate 7, figure 23 ; 

 last postembryonic whorl and a half white, banded just above, at, and 

 below the periphery with" hay's maroon; impressed sutural band 

 russet. The light color form occurring on 27 percent of the shells is 

 shown by an elongate shell (pi. 7, fig. 24) ; the postembryonic whorls 

 white faintly banded with pale olive gray at the edge of the periphery, 

 last half whorl at and below the periphery lined with black. Length 

 17.7 mm., greater diameter 12.0 mm., spire height 9.2 mm.

The color pattern of many of the forms existing in area 51 are not 

 very strikingly different from those of the forms obtainable from 

 area 56. The main difference is that the typical form of the shell 

 from area 56 has the embryonic whorls more intensely banded with 

 yellow than the shells of area 51, and a few color patterns (pi. 7, 

 figs. 19, 19a) are not found in area 56. 



The usual form and color pattern (pi. 2, fig. 4) has the first 

 embryonic whorl pale pinkish buff, remaining embryonic whorls upper 

 half white, lower half cream color; first half of first postembryonic 

 whorl white, banded just above the edge of the periphery with a 

 faint band of cream color, remaining postembryonic whorls white 

 with a line of ochraceous buff on the last whorl and a half just above 

 the edge of the periphery, last whorl at and below the periphery
