A, B, Quoy et Gaim. Voyage del’ Astrolabe, Pl. xvii. fig. 1, copied in Cuv. 
R. Ani. éd. illustr., Zooph. Pl. uxxxtv. fig. 1. The animal figured and 
described by Quoy and GaIMARD has round the mouth tubercles and no 
arms, is very flat, and resembles an Actinia ; EHRENBERG places this species 
with Meandrina pectinata, Meandr. areolata, and some others under a 
new genus Manicina. The singularly flat and thin leaves of this Polypary 
have given occasion to the name of Endive-Coral (lactuca). 
++ Stars convex. 
Monticularia LAM. 
B. Polyps secreting internally a hard body (Polypary stony, 
not affixed), 
Family XI. Fungina EHRENB. 
The stony polypary is here an internal induration of the animal, 
and is by EHRENBERG compared with the calcareous plate of Cephalo- 
pods (the back-bone of the Sepia). 
Fungina Lam. Polypary free, orbiculate or oblong, hemi- 
spherical or conical, above convex and lamellose, with an oblong 
central lacuna or gap, below concave and rugged. Star single, 
occupying the upper surface with lamellz denticulate or rough on 
the margin. 
Sea-mushroom. The numerous plates, running from the center to 
the circumference, give this Polypary some resemblance to a mush- 
.room, in which however the plates are situated beneath the cap. 
Some have an elongated form, and hence, in the names they bear, are 
compared to moles or slugs. 
The Fungie lie in clefts of rocks and cavities of coral-reefs, 
surrounded by branched corals, so that the force of the current is 
broken whilst the access of sea-water is not precluded. The older 
specimens are quite free: but younger ones are seated on a stem, 
on rocks, or sometimes are fixed to the dead remains ,of other 
Fungie ; in the pedunculate state they resemble the genus Caryo- 
phyllia Lam. The stem is at first hollow, and is afterwards filled 
with calcareous coral-substance ; the disc becomes larger, and at 
last the stem entirely disappears. 8. SrutcHBury, An Account of
