to be reduced to elongated points, widely separated from one another 

 A variety usually smaller, more depressed, and consequently with 

 wider aperture, and having a faint brown spot at the insertion oj 

 the columella, has been described by Dr. Westerhmd under the 

 name of H. recondita. I have had the types of the species fron 

 Mr. Westerlund ; they are identical with mine. It seems to me im- 

 possible to separate H. recondita specifically.' 



"A second variety, more like the type in general form, and ap 

 proaching H. recondita in the columellar spot, has been named b) 



me var. CONTAMINATA this variety frequently ha: 



the umbilicus partly open ; the coloration is like that of the type 

 but with the maculations or points more intense. It has below f 

 more or less interrupted chestnut band." 



" The third variety, which I have called UZIELLIANA (pi. 60, figs 

 76-80) is relatively very depressed, the columellar margin dark, th( 

 umbilicus decidedly open. It is the form which authors have look 

 ed upon as the type of the species, and called H. carseolana"
