CLASSIFICATION OF ZOOPHYTES. l]Q 



Family II. Sertl'Lakid-E. Ovules enclosed in ovarian vesicles ; biuls lateral, per- 

 sistent : coralla corneous, calicles sessile. 



Genera. Anfennularia, Pluniularia, Sertulnria, Thuiaria, Thoa, Pasythea. 



Family III. Campanularid.e. Ovules enclosed in ovarian vesicles ; buds lateral, 

 persistent ; coralla corneous, calicles pedicellate. 



Genera. Laomedea, Campanularia. 



Family IV. Tubularidju. Caducous gemmules growing from near the base of the 

 tentacles, and naked ; often coralligenous, coralla corneous, tubular. 



Genera. Pennnria, Tid)iilarin, Svncoryna, Corydeiidriuni, Eudendriuni, Corvna, Hv- 

 dractinia. 



UYLA, separating thus the fleshy species from the others ; tlie former including Lamarck's 

 orders, I., II., IV., and the latter, the remainder of his (jrders. The Zn()|,hvta Hcterohvla 

 arc subdivided as follows : 



1. Lithopliyta nullipora. NuUijiores, lately shown to be of vegetable nature, secre- 

 ting lime. 



2. Liihophyta porosa. The Madrepore tribe, excluding the Favositcs and Catcniportc. 



3. Lithopliyta lamellosa. The coralligenous AstrBeacea and Caryophyllacea. 



4. Litliophyta fslidosa. Lamarck's " Polypiers foramines." 



5. Ccratophijla spioitgiosa. Sponges, and sonic Alcvonida-. 



6. Ceratophyta tiibulosa. The Ilydroidea (excluding the HvdridaO, the Tubularidce 

 in ])art, and some of the Brvozoa. 



7. CeratopUyla foliacca. Brvozoa. 



8. Ceratophyta corticosa. The Anti|iathi and (iorgonidn-. 



9. Penncc marina. The Pennatulidaj. 



Blainville. — Blainville includes under the name Zoophytes, the fleshy Actinia; as 

 well as the coralligenous species, and also the Echinoderms, Acalcpha:, and Sponges. 

 The Sponges constitute his " Amorphozoaircs^^ and the other species, tlic " Actinozo- 

 aires." The " Actinozoaircs" are distributed as follows : 



Class I. " Cirriiodermaires," including the Echinoderms. 



Class II. " Arachxodermaires." The Acalephte. 



Class III. " Zoanthaires." The Aetinidte, Zoanthidffi, together with the coralligenous 

 Astra;acea, Caryophyllacea, and Madreporacea, excluding from the last the Autipathi, 

 MilleporoB, and Favosites, nearly as was done by Lamarck. 



Class IV. " Polypiaires." Includes the Millepora;, uudoi- which name Blainville 

 follows Lamouroux in comprising various unffilied genera, characterized bv' the small 

 non-radiate cells of the corallum ; and in other diyisions, the Brvozoa and Ilydroidea. 



Class V. " Zoophytaires." Corresponding to the Alcyonaria. 



We perceive in this classification a great advance beyond tliose preceding it. The 

 Alcyonaria, before widely distributed, are here united in a single group : the Aelinida' 

 are arranged with the coral polyps ; tlie Brvozoa arc mostly grouped together, and the 

 Hydroidca are brought into close association, although still the Ilvdra forms a sub-class 

 next to Jhe Sertularida.', instead of being united with them. 



Ehrenbehg. — Ehrenberg divides Zoophytes — his Anthozoa — into the two orders, 

 Zoocorallia and Phytocorallia. The former. " Animal Zoophytrf.^' contains the fleshy
