Mr. E. W. H. Holdsworth on new Species of Corals. 143 



The present form, though at the first glance t seems to have a 

 general resemblance to A. flabelliformis, is quite distinct from that 

 species, having the cells much larger and transversely oblong, not 

 round. Moreover, the zigzag character of the branches is much 

 more marked. It may, however, be worth inquiry whether it may 

 not be the A. infundibulifera of Lamarck. 



A. maderensis appears to show that the genera Stylasier and AU 



AUopora maderensis.

lopora ought to be united ; for though there are no " petites pointes " 

 or " tubercules vesiculaires " upon this coral (M. Milne-Edwards 

 giving this as one of the characters of Stylastef), yet the gemma- 

 tion is alternate and distichal — the same writer saying of AUopora 

 that its gemmation is " tout-a-fait irreguliere." 



Description of Two New Species of Corals belonging 

 TO THE Genus Flabellum. By E. "W. H. Holdsworth, 



F.L.S., ETC. 



1. Flabellum campanulatum. 



Compressed, campanulate ; borders straight or slightly convex ; 

 without spines. Base usually terminating in a small pedicel, some- 

 times irregularly compressed. Superior margin slightly arched. 

 Cell deep and narrow. Border of lamellae entire, sloping inwards 

 from the apex for about one-third of their length, thence continuing 

 straight to the bottom of the cell. Columella indistinct. Five prin- 

 cipal lamellee in half an inch. Height 14 Unes; breadth 16 lines ; 

 proportion of axes 7:16. 



Specimens in the British Museum are rather longer in proportion 

 than those in my possession ; but the variation is not very great.
