We owe to Loiimann a very full account of the Appendiculariidce 
collected during the Plankton Expedition ; which, as he has been able 
to include the examination of several other collections, almost amounts 
to a monograph of the group. In addition to a revision of the classifi- 
cation and definitions he describes a large number of new species, and 
also describes more fully the new species and genera which he had 
diagnosed briefly in his previous work. There is also a lengthy analysis 
of the geographical and bathymetrical distribution of the species.
