38. Oscillatoria additicia sp. nov. Plate 1, fig. 2.

Trichomes relatively short, straight, and comparatively rigid, 12-13 /j. diam.,
not constricted; cells pale aeruginous, contents homogeneous, one half to one

third as long as broad, 1-3 apical cells slightly narrowed, apical wall decidedly
thickened.

Growing in small masses attached to Amphiroa Tribulus, in the littoral belt,
Salinas Cove, near Guanica Harbor, June 27, 1915, Howe, 7209. Type and only
known collection.

The material upon which this species is based is very sparse and is mostly in
the hormogonial stage. There are, however, a few typical apices. The trichomes
resemble very much those of Hydrocoleum lyngbyaceum but there is no sign of any
sheath having been present and the apices are not quite typical. A study of more
and better material will be required definitely to establish the validity of the
species.	*
