LIMAX. 201 



L. bicolor, Selenka (Australia). Mr. Binney writes thus of this 

 species, as occurring in the States of our Atlantic seaboard : " It 

 inhabits cellars and gardens in moist situations in the cities. It 

 is considered noxious to vegetation. It feeds upon the leaves 

 of plants in kitchen-gardens, and upon the remains of the cooked 

 vegetables and bread thrown out from houses. Its most common 

 habitat is in cellars, where it makes its presence most disagree- 

 able by attacking articles of food, and especially by insinuating 

 itself into vessels containing meal and flour. The young suspend 

 themselves by a thread of mucus. The period of its introduc- 

 tion is not known. It was noticed by Mr. Say more than fifty 

 years ago."
