The appended account of North American earth- 

 worms has been drawn up largely from the works of Eisen, 

 Rosa, and Uhde. Only the oligochn'ta terricohr are given, and 

 probably the list of these will prove far from complete when 

 more attention has been given to collecting and studying our 

 species. The Lumhricus americanus, Perrier • {Becherches 

 2)our servir Vhistoire des Lumbriciens Terrestres, p. 44), which 

 is said by its describer to represent in New York the L. terrestris 

 of Europe, is probably one of the species of Allolobophora of the 

 list given below. The description of L. apii^ Kinberg, from 

 California, has not been seen. 



I wish here to acknowledge indebtedness to Prof. Forbes 

 for his kindness and liberality in the matter of special papers 

 on 01igochff;ta, and to Messrs. McCluer and Weed, who have 

 remembered me on several occasions with fine lots of living 

 specimens.
