be remembered, that the presence of a network of small rhabds 

 in the gastral cavity seems not to be a vaUd character, since 

 Breitfuss has found the same gastral network in specimens 

 of Sycon raphanus (Zool. Jahrbuch. Abth. für Systematik, XI, 

 1898, HO), and the same author also mentions (Mém. de I'Acad. 

 Imp. de St. Petersb. VI, 1898, 22) specimens of Grantia capil- 

 losa which showed slight distal cones and which he therefore 

 declares to be nearly related to Sycon raphanus.

This species I have not examined as it is not represented 



in our material; it was taken at North-Shannon (Die zweite 



deutsche Nordpolarfahrt; Haeckel 1. с).
