A solution to these problems awaits more careful and complete observations on the life history of this interesting sponge. Reference to the graph in figure 28 indicates that the larvae settling on shells suspended from the dock considerably outnumbered those settling on shells hung from the float. Since the shells in the latter location outnumbered the former, so that there was actually more surface area available for settling, it seems reasonable to expect a correlation with some environmental

LIFE HISTORY STUDIES 99 On the other hand, an anlysis of settling on white marble as opposed to dark gray phyllite fails to show any tendency for one to be favored over the other. Comparison of settling on both of these substrata, as well as on shells of Crassostrea virgiyiica (fig. 29) reveals that settling on the several types of backgrounds was es- sentially random. In the figure, half the total number of colonies which settled on oyster shells is shaded so as to permit comparison with similar surface areas on marble and phyllite. It is of
