 Corallum massive, large, more or less discoidal, composed of numerous- 

 long corallites. Corallites straight, prismatic, always in complete contact ; . 

 narrow, varying from i to 1.5 mm. in diameter; subangular in cross section,, 

 owing to non-uniformity of the wall in thickness ; usually 4-<5 sided. Mural : 

 pores few in number, but pretty large. Where three or more corallites come 

 in contact, walls often become much thickened and appear transluscent, thus 

 giving rise to the appearance of lucid asterisks at almost all angles of the poly- 

 gons in cross section. Tabulae numerous, more or less irregularly distributed, 

 about 12 in a space of 5 mm., thin, sometimes very undulating, often incom-- 

 plete and rarely coalescing. Septal spines rare, usually obsolete and seldom 

 developing to long spines, one or two rows of them being found in a number 

 of corallites, but not in all. 



Obs. — This is Favosites asteriscus of Frech, first described from the De- 

 vonian of Hoa-ling-pu, prov. Sze-chuan and characterized by beautiful lucid 

 asterisks in cross section and numerous undulating and often incomplete, in- 

 osculating tabulae, reminding of those of Hininotisia hemisphaerica, in iongi'-- 

 tudinal section ; the first mentioned feature seems also really to be constant, 

 because it is very characteristically exhibited by our example from quite a.-
