 A, B, QUOT et GAIM. Voyage de V Astrolabe, PL xvm. fig. i, copied in Cuv. 

 R. Ani. ed. illustr., Zooph. PI. LXXXIV. fig. i. The animal figured and 

 described by QUOY and GAIMABD has round the mouth tubercles and no 

 arms, is very flat, and resembles an Actinia; EHBENBEBG places this species 

 with Mceandrina pectinata, Mceandr. 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}. 



ft 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 EHRENBEKG 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 lamellse 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 Fungice 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 

 Fungice ; in the pedunculate state they resemble the genus Garyo- 

 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. S. STUTCHBUEY, An Account of 

 the Mode of Growth of Young Corals of the genus Fungia, Trans-
