 Greenland. 



TURBELLARIA. 



Obs. — The Planarice and Nemertece of Greenland have not 

 been studied since the time of Fabricius. The following list does 

 little more than show in what manner his species have been partly 

 interpreted, and does no justice to the richness of this branch of 

 the Arctic Fauna. 



1. Monocelis subulata (Fabr.). (Gr. Kekkursab-Kuma.) 



F. Gr. 308. 



2. Planama lactea, Miill. (Gr. Kumak.) 



F. Gr. 309.* 



* Doubtful species: — PI. operculata, Pabr. (F. Gr. 310), and PL caudata, 

 Miill., F. Gr. 310 (both by the Greenlanders termed "Kekkursab-Kuma," as 

 are other flat Worms). The latter is perhaps a naked Snail (CErsted, Naturh. 

 Tidsskr., IV., p. 546).
