so that I cannot give any particulars about its mode of adhe- 

 rence. The costee are closely covered for the greater part of 

 their length with a thin, rose-coloured, calcareous crust, which 

 seems to be rather a nulliporine growth than a true epitheca. 



The species is easy to tell from the following ; its affinities 

 are more with the American forms, from all of which it differs 

 in the absence of the sixth cycle, the small number of the 

 larger septal teeth, and the direction of the costal spines.

In a young specimen (produced by intracalicinal gemma- 

 tion) there are only three cycles of septa ; the columella is 

 low and consists of a few coarse trabecular. 



11. Cynarina*. 



Agreeing in all respects with Scolymia, except that the coral 

 is free when adult, turbinate, and covered with a thick epi- 

 theca. From Antillia it differs in having the costae roughly 

 spinose ; the free edges of the larger septa lacero-dentate, the 

 septal teeth increasing in size from within outwards, the 

 calicular fossa very shallow ; the calice circular in the adult,, 

 compressed in the young (the reverse being the case in Antil- 

 lia). From BomophyUia it is likewise distinguished by the 

 structure of its costal, septa, and fossa ; besides, Homophyllia 

 is always fixed by its base, and shows a very thin, appressed 

 epitheca, whereas the latter is thick and only loosely adherent 

 in Cynarina. 



■ I am acquainted with only one species referable to this 

 genus, 



Cynarina Savignyi. B.M. 



Coral turbinate, somewhat ventricose, ponderous, free. 

 Outside of wall covered till near the edge with a thick epi- 

 theca, through which, however, the costge and their spines are 

 visible. Costge unequal, prominent, roughly spinose ; scabrous 

 from being, covered with minute pointed granules. Calicle 

 circular, extremely shallow ; the free edge of the larger septa 



* From Cynara, a genus of phanerogamous plants, in allusion to 

 Scohpnia.
