For the lagoon form as described above I propose the name 

 forma laxa (Fig. 80). 



As above mentioned Penicilliis capitatus is a very common 

 species along the shores of the Danish West Indies. Regarding 

 its way of growing I refer to my earlier papers (see f. i. in »Biolo- 

 giske Arbejder tilegnede Eug. Warming«, 1911, p. 52), and shall 



only add here, that it is found 

 in open sea down to a depth 

 of about 40 m. growing on 

 ||K loose, sandy bottom.

Of this species only the 

 var. gracilis has been found. 

 It seems to be rather seldom 

 and seems only to occur more 

 scattered, in contrast to the 

 gregarious growth of P. pyri-

 a depth of about 30 meters. It grows on sandy and muddy bottom, 

 once it was also gathered on rocky coast.
