Abstract
THE greater part (pp. 522-686) of these two sections of the Handbuch is devoted to an account of the Scyphozoa contributed by Prof. T. Krumbach, of Berlin, He defines the class and gives a short history of the Scyphozoa, in the concluding paragraph of which he refers to the Tessera princeps of Haeckel and remarks that this owed its existence to Haeckel's need for a primitive form which, however, never existed in life. The Tesserantha connectens of Haeckel is a larval form of the imperfectly known rhizostome Leonura, and a similar larval form is known in the genus Cassiopea. The author describes each of the five orders of Scyphozoa, beginning with the Lucernariida and ending with the Rhizostomeae, giving under each a definition, a short history, the characters of the principal genera illustrated by schematic diagrams, accounts of the morphology, development., and physiology, references to recorded abnormalities, and brief discussions of the ecology, geographical distribution (with maps), and phylogeny. Appended to each section is a useful bibliography of the order.
