though occasionally very old specimens are found 

 that are even larger. 



^egula aureotincta^ Fbs., (Clilorostoma aureo- 

 tincti/t?i), the Gilded Turban-shell, is a southern 

 species with a shell resembling the last figure. There 

 are however, a few quite prominent spiral ridges with 

 more or less wavy crossings. The color of the shell 

 is gray, or sometimes almost black. The distinguish- 

 ing feature is a large umbilicus, which is marked 

 with a bright yellow stain, a circumstance which 

 doubtless suggested the name of the species. The 

 diameter of the shell is about an inch. 



liegula montereyi^ Kien., {Chlorostoma mon- 

 tereyi), the Monterey Turban-shell, was formerly 

 known as Chlorostoma pfeijferL The shell of this 

 rare species is strictly conical, with whorls almost 

 perfectly flat. The circular base likewise is flat and 

 nearly smooth, though marked with almost obsolete 

 spiral lines. The columella does not spread around 

 the umbilicus, which is funnel-shaped, white within, 

 and its edges dehned by an angle. The color is light 

 brown or olive, and the height of the shell, which 

 about equals its diameter, is an inch or more. 



liegula pulligo^ Mart., {Chlorostotjia pulligo)^ the 

 Dusky Turban-shell, much resembles the last species. 

 Its seven whorls are flattened, its base slightly con- 

 vex, smooth without lining, obliquely streaked, con- 

 cave and white around the deep and wide umbilicus, 

 which gradually expands and is partly covered with 

 a white callus, and has no spiral ridge within. The 

 color is dull purplish or brown, often appearing 

 orange when worn. The height of a large specimen
