bed and its geographica! distribudon is given. The section is cha- 

 racterized by the following peculiarities: cells solitar}^ or two toge- 

 ther; 1—2 chromatophores; setae very thin; resting spores found in 

 several of the species and probably occurring in all. The species are 

 markedly neritic, having their home in shallow coast-waters or in 

 lagoons, some in fresh water. 



A key to the marine species is given. C. H. Ostenfeld.

 videnskaberne. LI. p. 165—203. Kristiania 1913.) 



Verf. sucht die bekannten Ooc^'s^/s- Arten durch neue Beschrei- 

 bungen, wobei besonders der innere Bau der Zellen, der Chroma- 

 tophore, Pyrenoide u.s.w. berücksichtigt wird, zu karakterisieren. 

 14 Arten werden als gut karakterisiert aufgeführt. Als unvollständig 

 beschriebene, aber meistens wohl gute Arten werden 13 Arten auf- 

 geführt. Von diesen zusammen 27 Arten und ihren Varietäten 

 werden gute Abbildungen gegeben. 2 Arten werden als zweifelhafte 

 oder nicht aufklärbare Arten, wovon die meisten wohl zu streichen 

 sind bezeichnet. Als neu werden folgende Formen beschrieben und 

 abgebildet: Oocystis crassa Wittr. form, major Printz, O. solitavia 

 Wittr. form. Wittrockiana Printz, var. elongata Printz und Nzx.pachy-

As a result of a critical investigation of the structure and de- 

 velopment of the papillae, and more especially of the cystocarp, of 

 this species, with a view to determining its position more definitely, 

 the author states that "it would appear that Erythrophylliim delesse- 

 rioides, by virtue of the character of its fruiting proliferations, its
