 signification, instead of being rejected altogether. 



SUBGENUS FAVISTELLA. This name is here applied to a part of the 

 true Favosites, in which the cells are stellate with twelve distinct 

 rays, which in some species are quite broad. A species of this sub- 

 genus is well figured by Van Cleve in one of his plates of Western 

 fossils, and named Columnaria alveolaris.

GENUS VI. CATENIPORA. 



Favositidce, gemmis acrogenis uniseriatim latere aggregatis, corallo itaque 

 laminis verticalibus uniseriatim celliferis scepe sese inter secantibus in- 

 structo ; septis internis transversis numerosis. 



Favositidse with the buds acrogenous and aggregated laterally in a 

 single series; the corallum, therefore, consisting of vertical laminae, 

 often intersecting one another, and containing a single series of 

 cells; transverse septa numerous. 



The term chain coral, by which the fossils here included are fami- 

 liarly known, expresses well the appearance of the reticulated lines of 

 oval cells which a transverse section of the corallum presents. The 

 genus was named, by Lamarck, from the Latin catena, a chain. No 

 rays have been distinguished in the cells, and this fact led Lamarck 

 to place the group along with the Favosites, Millepora, Tubipora, 

 and some other species, in his division " Polypiers foramines." 

 Ehrenberg first arranged it with the other Madreporacea. This genus 

 is named Halysites, by Fischer, in his Oryctology of Moscow.
