A line coral dredged in Barbados agrees in every essential particular with 

 the description of the above species, except in the columella, which is con- 

 siderably thicker than in the figure of Mi-Edwards and Haime, so that it 

 scarcely deserves the name of lamellar, still it is much elongated and ob- 

 scurely trilobed, so that it may be simply a variety. Duehassaing. in his 

 Revue des Zoophytes et des Spongiaires des Antilles, 1S70, asserts that this 

 species is only a young and still simple corallite of a compound genus which 

 he has named OxysmUia rotundifolicb. The specimen in cpuestion is undoubt- 

 edly adult, and shows no signs of gemmation.

On re-examining the subject, it seems to me preferable to retain the generic 

 name of Axohelia, which 1 had joined to Madracis, for the species with com- 

 pact coenenchyma, and the latter name I'm- those in which it remains cellular. 



AXOHELIA M.-Edw. & II.

To Duchassaing's description ought to lie added that there are always ten 

 equal septa, hence it is no Stylophora The columella is pointed, and is hir- 

 sute a- well a- die septa. The branches are 8 to I" em. high, slender, 6 to 

 8 min. in diameter at tin- liase. Color while with purple polyps.
