I have, however, seen only one instance of this premature development, in a single statoblast contained in a small zoarium of P. fruticosa found in Lower Burma in March.

Other tubules of a very similar appearance but with a delicate chitinoid foundation appear to be the remains of a species of Plumatella of which they occasionally contain a statoblast.

B. Processes entirely surrounding the statoblast; many zoaria embedded in a common gelatinous investment so as to form large compound colonies Pectinatella, p. 235.

Three species of Lophopodella, all of which occur in Africa, have been described; L. capensis from S. Africa, which has the ends of the statoblast greatly produced, L. thomasi from Rhodesia, in which they are distinctly concave, and L. carteri from E. Africa, India and Japan, in which they are convex or truncate.

The statoblast is variable in shape and size but measures on an average about 0.85 � 0.56 mm.
