222 ZOOPHYTES. 



20. ASTRjEA ANANAS. (Ellis.} 



A. subhemispherica ; polypis 3-5'" latis. Corallum caliculis rotundatis, 

 subangulatis, scepe oblongis, incequalibus, contiguis ; interstitiis con- 

 cams ; cellis 2-3'" latis; lamellis denticulatis. 



Subhemispherical ; polyps 3 to 5 lines broad. Corallum with rounded 

 or convex calicles, subangular, often oblong, unequal, contiguous ; 

 interstices concave ; cells 2 to 3 lines broad ; lamellae denticulate. 



West Indies. Ellis, Lamarck. 



The calicles are much smaller than in the preceding, and are con- 

 vexly rounded instead of conical. 



Lesueur describes a coral, which he refers to the species figured by 

 Ellis, as having polyps without tentacles ; but it is probable that they 

 were only unexpanded in the specimen under examination. His. 

 figure agrees nearly with Ellis' s, and he states that the cells are some- 

 times trilobed. 



Mad. ananas, Ellis and Solander, 168, calicles a little distant, as in the spe- 



tab. 47, fig. 6. ciosa, but more conical ; cells four to 



Astrcea ananas, Lamk. ii. 406, No. 5. five lines long, one and a half to two

, Lamour., Exp. 59, tab. 47, fig. 6 ; berg refers this figure to his Explanaria 



Encyc. 127. (our Orbicella) ananas, which he makes

A. subglobosa, brunneo-fuscescens ; polypis J" latis. Corallum cellulosum ; 

 caliculis rotundatis, subangulatis, contiguis, subtequalibus ; cellis sub-
