TABULAR VIEW OF THE CLASSIFICATION OF ZOOPHYTES. 
LOOPHYTES. 
Animas of the class Radiata: usually attached at base: having a 
coronet of tentacles above, and an edentate mouth at the centre: 
within, an alimentary cavity, to which the mouth is the only opening: 
androgynous ; gemmiparous and oviparous : nerves indistinct (?) : cir- 
culation very imperfect : no special organs of sense. 
Orper I.—ACTINOIDEA. 
Visceral cavity enclosing the stomach, and divided into compart- 
ments by radiated lamelle, having reproductive functions; ovules 
ejected through the mouth. 
Susorprr —ACTINARIA. 
Tentacles 6, 12, or more, in number, not papillose, (with few ex-. 
ceptions,) and perforate at apex: often coralligenous ; coralla calca- 
reous, very rarely corneous, cells radiate with lamelle. 
Tribe I.—ASTR/ZACEA. 
Tentacles many, in imperfect series or scattered; when gemmi- 
parous, gemmation superior, the polyps widening above: often coral- 
ligenous ; coralla calcareous, cells multiradiate, lamelle prolonged 
outward beyond the cells, and hence the surface in aggregate coralla 
is lamello-striate. 
Famrty I, Acrryipx. Not coralligenous, usually attached. 
Genera. Actinia, Anthea, Adamsia, Edwardsia, Ilyanthus, Capnea, Actinecta, Epi- 
cystis, Actinodendrum, Lucernaria, Metridium, Actineria, Heterodactyla, Epicladia. 
Famiry II. Astraip#. Calcareo-coralligenous ; tentacles arranged along the mar- 
gin of the disks; disks sometimes confluent in simple series; coralla, with excavate cells, 
stars circumscribed, sometimes lobed or linear; lamella, in aggregate coralla, interrupted 
usually along the middle of the septa.
