Vet. Ak. Handl. Bd 6, K:o 18, 21. 

 Type : D. involutum long confounded 

 with Clisioph. Hisingeri Edw. H., which 

 in reality is a Devonian coral from the 

 ilorth of France. Polypary simple, never 

 found In compound masses, conical, epi- 

 (heca strongly ribbed and with a bluntly 

 prominent ridge opposite a narrow septal 

 groove in the calice. The septa form in 

 the median axis a whorl, which is ele- 

 vated and columella like. The tabulae 

 are also elevated toward the central axis. 

 Near the epitheca there exists a peculiar 

 kind of intraseptal structure, consisting 

 of narrow twisted strings of whitish 

 colour, such as are not seen in anv 

 other coral. S.

 Streptelasma as Hall 28:th Rept., 106, 

 states; the same genus occurs as well in 

 the Devonian of Eifel and of Spain, from 

 where Ch. Barrois has described a spe- 

 cies. The Eifelian species is commonly 

 called Cyathophyllum proles Goldf, S.D.

 has however been applied by Geinitz

 forms of Heliolites and others. 



Fascicnlaria Dyb. 1873. Mon. I, 80, 

 II, 202. This is no doubt a well estab- 

 lished genus, but as the name is already 

 given by M. Edwards to a brvozoan a 

 new one must be adopted. Type: F- 

 dragmoides. S. D.

Faviphyilum Hall 1852 in Stans-

 and seems to be a highly altered Cyatho-

 and I cannot find that the name occurs 

 elsewhere.
