Note {459} — Chapter VIII · UNITY OF TYPE IN THE GREAT CLASSES; AND MORPHOLOGICAL STRUCTURES
Reading edition
In the margin C. Bell is given as authority, apparently for the statement about Plesiosaurus. See Origin, Ed. i. p. 436, vi. p. 598, where the author speaks of the “general pattern” being obscured in “extinct gigantic sea lizards.” In the same place the suctorial Entomostraca are added as examples of the difficulty of recognising the type.
