Genus DACTYLOCOCCOPSIS Hansgirg 1892. 
Dactylococcopsis acicularis Lemmermann. 
Ber. d. D. bot. Ges. 18: 309. 1900; Kryptogamenfl. d. M. Brandenburg 3: 
Algen 1. 51, 44. /. 5. 1907.

The cells of this species that have been observed have a parie¬ 
tal ehromatophore. Lemmermann does not state this fact in 
his original description of the alga, but parietal chromatophores 
have been described in the genus by G. S. West (Brit. Preshw. 
Algae p. 348. 1904). The presence of a parietal chromato- 
phore suggests that the alga is possibly a member of the 
Chlorophyceae but since its color is a pale blue green it should 
be placed in the Myxophyceae. ’(Plate 14, figs. 2-4).
