Prom icoXos 'broken' and Xo'0o9 'a ridge.' 



[In Ann. Mag. Nat. Hist. ser. 6, vol. xvii. p. 289.] 



SYNONYMY : 



Constellaria, 1854, non Dana, 1848. 

 Radiopora, pars, Pictet, non D'Orbigny, 1852. 



Diagnosis. Theonoidse in which the zoarium consists of flat, 

 encrusting sheets, formed of numerous radial groups of zocecia. 

 The radial ridges are broken up into groups, the arrangement of 

 which is irregularly linear. 



Type species. KololopJios terquemi (Haime), 1854. 



Affinities. The type species of this genus was referred by 

 Haime to Dana's genus Constellaria, Which at that time was mis- 

 understood. The American fossil has been redescribed by Ulrich, 1 

 and it is quite different from this species. There is a certain 

 superficial resemblance, due to the prominence of radial, non- 

 poriferous lines; but in Constellaria these lines are solid " maculae" 

 (of Ulrich), and in Kololophos they are depressions between zooscial 

 ridges. 



The nearest ally of this genus is Actinopora. Prom this it 

 differs by the confluence of several radial groups into one sheet, 

 and the broken, interrupted character of the ridges.
