Gloeocapsa quaternata major var. nov.

Plate 3, figure 27

Families composed of 2, more rarely of 4, cells, broadly ellip-
soidal, 13-15 m long, closely crowded together but not confluent;
cells 3.5-4.2 jj diam. and 6.7 p long without tegument, homogene-
ous, aeruginous; tegument very distinctly lamellose, hyaline, be-
coming yellowish brown with age.

Growing on the wall of an old conservatory, San Juan, no.
131 a, type.

The variety is to be distinguished from the species in having
larger and ellipsoidal colonies, in having elongated cells and in
having yellowish-brown tegument on the surface of the stratum
when aged. The cells are distinctly elongated, a character not,
strictly speaking, that of a typical Gloeocapsa, but the cells
divide in three planes, thus excluding it from the genus Gloeo-
thece.
