CARL SKOTTSBERG, MARINE ALGiE 2. RHODOPHYCEiE. 



Two growing tips are illustrated in fig. 17 a — b. The structural principle is the same 

 as in Phycodrys, birt in the new genus we find a marked difference between the lateral 

 branches, as of each pair only one, alternately right and left, develops into a marginal 

 tooth, while the other appears reduced. The slight difference in the anatomy is, perhaps, 

 of less importance, although the monostromatic medulla (fig. 17 c) is quite conspi- 

 cuous. The anatomy of Neuroglossum Andersonianum seems to be the same as in my 

 species. The cystocarps are unknown in both. Nött, Nitophylla of Oalifornia p. 32,

brought Neur. Andersonianum to Nitophyllmn, without an examination of the apex. 

 His figure (pl. 9 f. 45) shows that it is not conspecific with my species. The prostrate 

 part of the frond spöken of by Nött is absent in the latter, where I observed the erect 

 frond springing from a small basal disc, that also emits a few hapters.
