AIR-BREATHING SNAILS AND SLUGS

little shell was collected under leaves near Seattle 

 by Mr. P. B. Randolph. It is of a dark, reddish- 

 brown color, and it has a silky luster. 



Fristoloma lansingi^ Bland, Lansing's Zonite, is 

 found in damp places under leaves, in Oregon and 

 Washington. The little shell is scarcely 3 mm. in 

 diameter, but it has five or six whorls, a rather ele- 

 vated spire, but no umbilicus. The lower end of the 

 narrow aperture is almost immediately beneath the 

 apex. In appearance it is shining and dark horn- 

 colored. 



Fr'istoloma stearnsi^ Bland, Stearns's Zonite, has a 

 similar range, but also reaches into Alaska. It re- 

 sembles the last species, but is more elevated, more 

 striate, and it has seven whorls. Its diameter is 4 mm. 



During the months when rain falls upon the Pa- 

 cific Coast a stranger is apt to be startled by meeting 

 specimens of a yellowish slug of a remarkable size; 

 but old residents are used to them and are not at all 

 disturbed, though very few express any appreciation 

 for the slippery things. In damp and shady places 

 they are active all of the year, though in the time of 

 summer drought they are seldom seen in the fields. 

 A picture of a half-grown specimen is given in

 inches or more, and look as if they were exceedingly 

 well fed. While speaking of food we may remark
