" This shell is a better t} pe of this form of Dijilommatina than 

 the very tumid shell first described from Asalu ; the form changes 

 much in different localities, in some being mueli more solid and 

 more distinctly and distantly sculptured near the apex ; a variety 

 from the Eastern Burrail is 0-20" in alt., rich dark amber coloured, 

 has the 3 lower \A'hor]s smooth and glassy, the columellar tooth 

 still more remote, and the constriction just behind the peristome ; 

 it departs so widely from the original type tl:at it might almost be 

 separated." {Godwin- Austm.)
