176 REPORT—1883. 
In the first family M‘Coy placed Paleozoic genera—such as Ptilodictya 
and Berenicea, and in the third Phyllopora (Retepora), Glawconome 
= Penneretepora, D’Orb., Acanthocladia, King, and also Fenestella. With 
these were associated recent and fossil Polyzoa (not Paleozoic), belong- 
ing to Cheilostomatous genera, which were not at that time so distin- 
guished by authors.

In the ‘ Annals and Mag. of Nat. History,’ and also in the ‘ Mono- 
graph of Permian Fossils,’ Prof. King established the following family 
grouping for the inclusion of genera and species founded by himself or 
by others.

1849. E1asmoporipa, King. 
Genus Elasmopora = Millepora celluiosa, Linn. (type). 
This family founded upon the above type is inadmissible as a Paleo- 
zoic representative group. 
1849. THamniscipa, King. 
Genus Thamniscus, King. 
? Syn. Ichthyorachis (pars), M‘Coy. 
Genus Acanthocladia, King. 
As some of the family and also the generic names will be retained in 
this Report, it may be advisable to direct attention to a few particulars 
furnished by the author. 
The sub-class in which the Permian Polyzoa are placed by Prof. 
King is the Ciliobrachiate of Farre, and the synonyms of the sub-class 
are given by him in the following order :—Poryzoa, J. V. Thompson; 
Bryozoa, Ehrenberg ; Zooruyta Ascrporpa, Johnston; Potypes TUNICIENS, 
Milne-Edwards. ‘The divisions Infundibulata and Hippocrepia proposed 
by M. Gervais, as based chiefly on difference of habitat, whether marine 
or fresh-water, appear so divested of the necessary structural in- 
dividuality, and of so little value compared with the orders already 
noticed, that in place of adopting them it seems a much safer plan to 
regard the Ciliobrachiates as resolvable into only one order, for which 
Ehrenberg’s name Bryozoa may be very conveniently retained.’ ! 
1846-1851. Hacrnow. 
In the classification of the Cretaceous Polyzoa? by Friedrich V. 
Hagenow, the author adopts some of the genera previously established by 
Lamarck, Blainville, or Milne-Edwards, and also adds some few of his 
own. The genera adopted from Goldfuss and Lamouroux are redefined,
