(1897, p. 31) that Otto's type-specimen, preserved at Breslau, was 

 undoubtedly A. pentagona. The necessity of the change was pointed 

 out by Schneider (1898).

The eudoxid (Aglaismoides eschscholtzii Huxley) was taken at 

 Station 5616, 19 specimens. 



This small series, not in very good condition, does not add any- 

 thing of importance to the previous descriptions of the species. It, 

 or its eudoxid, was taken at 33 stations by the Siboga, and 22 by the 

 Albatross in the eastern Pacific. Lens and Van Riemsdijk (1908) and 

 the writer (19116) have discussed its relationship to tetragona, and 

 the characters which distinguish its nectophores and eudoxid from 

 that species.
