Much more elongated than B. in flatus, melo, and the allied forms, 

 the diameter and long axis of aperture being about half the total 

 length of the shell. The exceptionally large, high, and very finely 

 pitted nepionic shell is characteristic. No subspecies can be dis- 

 tinguished with present knowledge, but there are several well- 

 marked variations. 



Figures 21 to 26 represent the typical form, of which B. trilineatus 

 (figs. 25, 26, type) and B. sayi (fig. 24, type) are synonyms. It 

 varies chiefly in the number and intensity of the stripes, which vary 

 from deep chestnut to translucent gray. 



Fig. 29 is drawn from a King George Sound specimen (Dr. Cox's 

 collection) of a straw yellow color, varied only by a small dark 

 umbilical crescent. 



Fig. 27 represents a large specimen from King George Sound 

 (Cox collection), which is quite swollen, not tapering, below.
