of the species from Griind, first described by Frech, in one species — C. Iictcro- 

 pJiylloides; the type specimen of Frech bears a little less numerous septa 

 than the fossils from Poland and China, and shows the outermost layer of 

 vesicular dissepiments occupied by horizontal but not oblique vesicles. For 

 a while, however, we follow the opinion of Gukich, in taking all of them speci- 

 fically identical ; the question can not be settled with out the detailed study 

 of more material. 



Localities and Geological Age : — South of Ping-yi-pu, Ping-wu-Hsien, 

 prov. Sze-chuan, and Lao-sa-tei, Hsing^an-hsien, Kuei-lin-fu, prov. Kwang si. 

 At the first locality, this species is found in association with Cyatliophylliivi 

 cacspitosuui var. brcviseptata, and at the htter, with Pachypora reticulata 

 and Stromatopora / sp. 



Devonian, and probably Middle Devonian. 



C. Jictcropltylloidcs is known from Grund, Germany and Kadzielnia,

Corallum composite, massive, composed of numerous straight, columnar 

 corallites. CoraUites more or less irregular in cross section, 4-6-sided, some 

 4-6 mm. in diam. Walls of the corallites thin, but strong. Septa in two- 

 distinct orders; longer ones 14-16 in number, ^hin, but thickened at their 

 ba,se, not quite extended to the veiy center of the corallites. Shorter ones, 

 in alternation with the longer, quite rudimentary, often hardly vi.sible. Dis-
