TRIBE I. ASTR^EACEA. 299 



This species has some resemblance to the two described by Quoy 

 and Gaymard ; but the character of the teeth and of the under sur- 

 face, is quite different. The lamellae also are more unequal and dis- 

 tant. It is possible, however, that it may prove to be the crassitenta- 

 culata, on a re-examination of that species. 



12. FUNGIA ACTINIFORMIS. ( Quoy <Sf Gaymard. ) 



F. orbicularis, convexa, subtus planiuscula ; tentaculis longis, cylindricis, 

 fuscis, apice subluteis. Corallum lamettis sub&qualibus, lobato-den- 

 tatis ; subtus, lamello-striatum, striis tenuiter denticulatis. 



Orbiculate, convex, below nearly flat; tentacles long, cylindrical, fus- 

 cous, with yellowish tips. Corallum with subequal lobato-dentate 

 lamellae ; below lamello-striate, with the stria3 finely denticulate. 



Island of Cocos. Quoy <$ Gaymard. 



Quoy and Gaymard's figure represents the lamellae with rounded 

 teeth, often nearly a sixth of an inch broad, separated by narrow acute 

 interstices. This coarse dentation, united with the fine denticulate 

 striae below, distinguishes the species from the others here described. 

 The specimen measured four inches in diameter, was regularly convex 

 above, an inch thick at middle. The tentacles according to the figure 

 are about an inch long.

13. FUNGIA CRASSITENTACULATA. (Quoy $ Gaymard.) 



F. orbicularis, planulata ; tentaculis conicis, crassis, apice luteo-virescen- 

 tibus. Corallum lamellis incequalibus, valde lobato-dentatis, majoribus 

 alternis ; subtus, regulariter striatum. 



Orbiculate, flat ; tentacles conical, stout, greenish-yellow at tip. Co- 

 rallum with unequal lamellae, strongly lobato-dentate, the larger 

 alternate ; below, regularly striate.
