quently somewhat eroded. The body-whorl is 

 puckered near the suture, the umbilicus is nearly 

 closed, and the columella is set with two little white 

 knobs near its base. The common length of the 

 shell is less than an inch, but sometimes old speci- 

 mens are found which are considerably higher. 



The variety subaperta^ Cpr., differs from the regu- 

 lar form in having more prominent spiral ridges, 

 which are usually more roughened, and in having 

 a prominent umbilical pit. It lives in the Vancou- 

 ver district.

 of yellow on the base, just below the columellar 

 teeth. 



T^egula hrunnea^ Phil., {Chlo- 

 rostoma brunneufn)^ the Brown 

 Turban-shell, Figure 236, is a fine 

 species, living on the rocks which 

 are exposed only at very low tide, 

 or on the seaweed. It has a hand- 

 some, rich brown shell, with a por- 

 tion of white around the aperture. 

 The lines of growth are very oblique, and are easily 

 recognized. The figure represents a large specimen,.
