It is impossible with the material at hand to consider the above as more than geographical races of the same species. Nevertheless the individuality of each colony is remarkable and leads to the suspicion that every island is developing or has developed one or more species of Dendrotrochus. A careful examination of the anatomy of the animal from many of the above localities, fails to reveal any noticeable differences. The foot is as described by Hedley (Rec. Austr. mus., 1895, p. 91, pi. 25). The reproductive organs are also similar to those described by Hedley, several specimens containing one or more large spermatophores, the spermatheca being swollen almost to the bursting point. The radula (Fig. 18, 19, M. C. Z. 32,473, slide 1,864) is similar to.
