that the cell rising from the germinating spore is not different from the cells 

 which it produces. To judge from the figures of Bornet and Thuret the spor- 

 angia become a little larger in 

 Ch. corymbifera than in Ch. 

 Nemalionis, namely up to 22 

 long. It is interesting that this 

 species hitherto only known 

 from the Mediterranean and 

 the Gulf of Gascony has been 

 found in the Limfjord, a water 

 with relatively high salinity 

 and summer temperature.

The greater part of the 

 frond of this species grows in 

 the thick outer wall of the 

 Bryozoan Alcyonidium gelati- 

 nosum. The endozoic filaments 

 are dichotomously branched 

 and give off numerous free, 

 short , branched fertile fila- 

 ments bearing monosporangia.
