TRIBE I. ASTRJGACEA. 221 



This is a neat species, with large prominent subcylindrical calicles 

 often a little distant, and deep cells. The texture is light cellular ; 

 the dissepiments within are extremely delicate, and on the lateral sur- 

 face of the lamelke they are quite oblique. The species resembles 

 the A. Orbicella radiata, but besides being more light and delicate in 

 texture, it increases by disk buds. 



Madrepora radiata, Esper, Fortsetz. i. 74, near the speciosa, in having prominent, 



tab. 61. A characteristic figure, though nearly cylindrical, circular calicles, with 



coarse. Esper alludes to the lightness of plano-convex interstices ; but the figure 



the coral, and its very cellular texture. they give as representing it, has the in- 



The Astrcea annularis, of Quoy and Gay- terstices a simple ridge, perhaps a little 



mard (Voy. de 1'Ast. iv. 209, pi. 17, sulcate. The calicles are described as 



figs. 17, 18), as described by them, is three or four lines in diameter.

 nulis, subangulatis, rotundato-conicis, contiguis (itaque sulcis inter- 

 mediis subacutis), extus confertim lamello-striatis et denticulatis ; ce.ttis

Polyps prominent and often 9 lines broad. Corallum with the 

 calicles 1 to 2 lines prominent, subangular and rounded conical, 

 contiguous (and hence the intermediate sulcus subacute) ; exterior 

 crowdedly lamello-striate and denticulate ; cells 4 to 5 lines broad, 

 and often elongated. 



China Sea. Esper, from M. Chemnitz. Red Sea, Ehrenberg. 



This coral resembles somewhat the A. Orb. argus, in its conti- 

 guous conical cells and striated exterior, but has much larger calicles, 

 which elongate and subdivide. Esper's figure represents a convex 

 mass 4 inches across, with some of the calicles nearly an inch long. 

 He states that the lamellae within the cell are minutely appendiculate 

 at base.
