From Colaiinian'd (tl reahtUi, GuhUuss, and ('. linJli, Nicliolson, the 

 present coral is distinguislied by a much less number of septa, and trom 

 the latter also by the tact that the septa are plain and non-denticulate 

 along the free edges.-' The mode of growth iu another American species, 

 ('. riKjosa, Billings, is quite diffex-ent — "an aggregation of circular or 

 I'ounded polygonal coiallites,"* and the septa amount to forty. C. cdlicliM, 

 Nicholson, is a more diminutive species, the corallites comparatively lax 

 and discrete in their mode of growth, with an average of twenty-eight 

 septa. C. dit<ji(iicta, Wliiteaves, is an extreme form of the genus in which 

 the coi'allites are generally free, with usually thirteen septa. '^ Several 

 other American species have been described, but I regret I have not 

 access to the literature bearing on them. 



In 1897 I described a small coral, for whicli I was indebted to the 

 late Rev. Father Dowling, then of Bathurst, and to which I gave the 

 name of C. pattciseptataj^ There are certain anomalous characters in this 

 coral, but on the whole, I have not, up to the present, seen any reason to 

 change the generic reference. A second Australian species occurs in 

 Victorian rocks, C. cre^isireUi, Chapman, for whicli the author suggested 

 the sub-generic title of Luijolop)hylluviJ but the species is clearly not a 

 typical Cohnnnaria. Mr. Chapman wrote: — "The intermediate calicular 

 pouches [interseptal loculi] are traversed in the outer zone by endothecal 

 or vesicular tissue iu the form of curved dissepiments, the latter rudely 

 concentric." This structure so entirely departs from that typical of 

 ('olam.)uiria that I would suggest to Mr. Chapman the advisability of 

 considering his name of generic rather than sub-generic rank. 



Several European species exist, sucli as G. snlcnla, Lonsdale (non 

 Goldfuss),*^ found in Russia ; C. [lothlandica, Ed. and H.,'-* and possibly the 

 species referred by Dybowski to his genus G yatliopliyll oi den }^ — G.fusciculiis, 

 Kutoi'ga, and G. irregular in, Dybowski. The two first-named are clearly 

 of the type of G. aveolata, and therefore quite distinct from the present 

 species.
