TRIBE I. ASTRJEACEA. 305 



Large, much elongate, full twice as long as broad, strongly convex 

 and laterally compressed ; below deeply concave. Corallum very 

 stout, lamellae coarsely dentate, not granulous, teeth rounded, often 

 l to 2 lines broad, oririme 4 to 5 parted ; below very crowdedly 

 echinate.

This species resembles in its lamellae the gigantea, of which I have 

 suspected it to be a variety; but it is much compressed laterally, 

 and often a little distorted, and the teeth are larger. One specimen 

 measures ten inches long, three and a half broad, and three and 

 a quarter high, with below a concavity two inches deep, and the 

 corallum one and a half inches thick. The oririme moreover is 

 subdivided. 



Rumph. Amboyn. vi., fig. 2, tab. 88, may be this species. 



GENUS II. CYCLOLITES. LAMARCK. 



Fungidce liberce, non gemmates, itaque simplidssimee ; ore centrali. Co- 

 ralla superne centra depressa et lamellis radiata; subtus concentrice 

 striata, nuda. 



Free Fungidae, not budding, and therefore quite simple ; mouth cen- 

 tral. Coralla above, with a depression (oririme) at centre, and sur- 

 face radiated with lamellae ; below, concentrically striate, naked. 



The Cyclolites are fossil species of small size, resembling closely 

 the Fungiee ; and some of the latter have distinct traces of concentric 

 striae below, or lines of growth, somewhat like the former. Yet the 

 general habit of the two are different, and the Fungiae are always 

 papillose or echinate on the under surface, with the radiating lines 

 far the most decided. This genus was established by Lamarck. 

 Goldfuss unites it with the genus Fungia. Blainville states that the
