The form is like H. eddystonensis, from which this variety differs 

 in having the upper whorls red or dark purple. It is straw-yellow, 

 unicolored, or with one or two bands at the obscurely angled periph- 

 ery. The lip is broadly expanded, white. Sculpture as in H. eddy- 

 stonensis. 



Small island near Eddystone Id. 



Brazier found this form much more abundant than typical gelata, 

 which inhabits" the same island. He enumerates many varieties of 

 striping (see below). The figures on my plate are drawn from 

 authentic specimens. 



Var. a. Light-yellow, ornamented with one broad chestnut-band 

 on the periphery and continuous at the suture. 



Var. b. Darker yellow, ornamented on the base with two fine 

 lines on the periphery, two wider and a fine one below the suture. 



Var. c. Nearly white-, base with one broad band nearly black, 

 periphery and upper part ornamented with three broad bands. 



Var. d. Light-brown, base ornamented with one narrow chest- 

 nut line, periphery with two rather broad, white lines at the suture ;

Var. e. Bright straw-yellow, two narrow reddish bands on the 

 periphery, apex light-red. 



Var./. Light-yellow, nearly white, the periphery ornamented
