Specially modified cells occur at the ends of the “ tactile processes ” 
and between these bodies are tufts of settn. Eimer has no doubt that 
nerves end in the cells and seta) ; the latter are tactile, and although the 
former may receive impressions they probably only seoroto a viscid sub- 
Btanoo.

This is the same as Fritz Muller’s species, Tamoya haplonema, but has 
been placed by Claus in his genus CharyMea. Greene gives an account 
of the bibliography of the Charyhdeidai.

The homology of the Ctenopliora and the Ilydrozoa will no doubt be 
further w'orked out by Haeckel, but the anatomy of Ctenaria ctenopliora, 
g. & sp. nn. (order Gymnohlastea-Anthomeduscc, fam. Cladonemiden), and 
other allied forms, has proved almost beyond a doubt that the true 
homology of the Ctenophores is not, as formerly supposed, with the 
Anthozoa. Ctenaria possesses on the outer surface of the umbrella (ex- 
nmbrella) eight rows of modified cells — not ciliated — but homologous 
with the eight rows of swimming plates of the Ctenopliora.

The present volume deals in a most complete and exhaustive manner 
with the group Ilydromedusce, for which, rejecting his previous term, 
uApliacellce (1878), Haeckel adopts Gegenbauer’s term Craspedotce. 
Craspedoke are defined as Meduscc devoid of gastral filaments (phacellae); 
with ectodermal gonads, and a true velum ; devoid of true marginal 
lappets ; with a double centralized nerve-ring ; phylogenetically (in all 
probability) and outogenetically (up to the present in the majority) they 
are descended from Hydroid polyps devoid of gastral filaments ; onto- 
genetically there is mostly an alternation of generations ; the sexual 
Craspedote-geueration is derived by lateral budding from the asexual 
Ilydrostome-generation. Craspedotce, according to Hasckel, may be divided 
into two grades: 1. Leptolince\ Craspedotce, sometimes devoid of otocysts, 
sometimes with velar marginal bodies, with ectodermic otolithic cells ;
