and make up the remainder of the thickness of the walls. The growth stages 



are as follows: 



Width. Length. Ratio. 



Whorl 1 25 .5 1:2 



Whorl 2 403 .92 1:2.29 



Whorl 3 610 1.4 1:2 .72 



Whorl 4 875 2.05 1:2.34 



Whorl 5 1.2 3.02 1:2.53 



Whorl 6 1.633 4 .4 1:2 .7 



Whorl 7 2.165 5.95 1:2.74 



Whorl 8 Incomplete 



The total length of the shell is 7.8 mm., and the diameter 2.65 mm., 

 giving a ratio of 1 to 2.94. The slit is .016 in the first whorl and .0402 x .175 

 in the fifth whorl, occupying less than half the space between the whorls. 

 It expands more rapidly in width than is the case in G. rohusla v. Staff. 

 In general form it bears little resemblance to that species. The ratio of that 

 spacies, as given by von Staff, is abaut 1:1.7.
