III.—Notes on Yunnan Cystidea. III. Sinocystis compared with similar Genera

Published online by Cambridge University Press:  01 May 2009

Extract

Essentially the pores of Megacystis are diplopores, for they are arranged in pairs. This is evident on the inner surface of a plate (E 16169, E 7671). Here each pore-pair lies in a shallow depression, and each pore again lies in a slight depression at the bottom of this (fig. 14). Compare Sinocystis yunnanensis (antea, p. 538).

page 113 note 1 The term “peripodium” was extended to these structures by Lovén (1883, Pourtalesia, p. 57), since he believed that tube-feet sprung from them as from the similar structures in Echinoidea. It seems advisable to drop this use of the term, along with the belief that it implies.
