(PI. IX, fig. 9). It bears a few conceptacles of cystocarps which are conical and about 1 mm. 

 in diameter, when seen from above. In structure it coincides in the main with the type of the 

 species (Fig. 20 B). What makes it uncertain, however, whether this form in fact belongs to 

 the species in question, is that the cystocarpic conceptacles are considerably smaller than those 

 of sporangia in the type. But the specimens appear to be stunted, and it may be that the 

 said organs are larger in better developed specimens and show the same variation in size/as 

 e. g. Goniolitkon Fosliei and other species. Nor can be jndged from a solitary specimen of the 

 type only hearing a few conceptacles of sporangia, whether the latter are as a rule of the 

 quoted size, or perhaps partly smaller. Therefore, there seems at present to be no reason to 

 classify this form as a denominated one, far less as an independent species. 



The above species is plainly distinguished from any other species known of this genus. 

 It seems to stand nearest to G. Fosliei, but distinguishes itself by essential characteristics. In habit, 

 however, it rather approaches certain forms of Lithothamnion fragilissimum and L. simulans, 

 and sterile specimens may be easily confounded without closer examination. 



Occurrence: As mentioned above, only one specimen is known of the type of the 

 species. It was collected at stat. 129. Of the said differing form two specimens have been 

 brought home from stat. 93.
