'O 



about one-third of its length distant from its anterior ex- 

 tremity. Length rather more than one inch. 



Geographical Distribution. Noticed hitherto only in 

 the neighborhood of Boston. 



Remarks. In this species the head alone projects from 

 the mantle, no part of the neck being visible. It is constant- 

 ly covered with a watery mucus, and suspends itself by a 

 mucous thread, like many other species of this family. I 

 have not noticed any varieties of colors or markings. It 

 occurs only in small numbers, in company with Limax agres- 

 tis, under stones at road-sides. I give this species with some 

 hesitation, for the foreign descriptions and figures generally 

 do not apply to it, and unless two species are confounded to- 

 gether, the differences of color and markings in the varieties 

 are truly extraordinary. Ferussac's description of the variety, 

 " griseus, unicolor, fasciis nigris," is however so very applica- 

 ble to ours, and the figure referred to represents it so well, 

 that I cannot doubt that our animal is identical with that va- 

 riety. From its restricted locality, and small numbers, it is 

 probably an introduced species. It may, however, prove to 

 be a distinct species, and comparison of the foreign and native 

 animals can alone decide its character.
