  • Discussion

    PLATE 2, FIGURE 23

    The collection of Gloeocapsa mentioned above seems very close to G. Uvula (Carmich.) Kuetz., judging from the descriptions and illustrations of Kuetzing, Hassall, and Meneghini. In its present state of development the cells, in a large part, gravitate from each other after each division, but remain within the same colonial tegument. Generally they are to be found in groups of four. Certain other colonies may contain as many as sixteen cells before disintegration of their teguments. In the description of G. livida it is stated that the families contain "16-24 cells."
