3 complete cycles (24 septa) and a fourth, incomplete. The single septa greatly resemble 

 each other so that it is impossible to judge from their appearance to which species they belong. 

 As a rule only two kinds of septa are found in a calyx, a comparatively large one alter- 

 nating with a comparatively small one. 



The lateral surfaces of the septa are almost smooth, though diagonal rows of slightly 

 protruding granulations may be seen running inwards and downwards. The upper edge 

 of the septum is uneven, finely dentate, further down the edge is wavy. Dissepiments often 

 occur in the interseptal compartments, many appearing at the same height. The hollow 

 beneath the calyces fills up cjuickly as a rule, but sometimes we find long pieces of the trunk 

 with open interseptal compartments without dissepiments. 



There is no columella. In the deeper sections of the trunks however, we observe that 

 the septa coalesce by the help of their slightly billowing edges, turning towards the center, 

 without tliough forming an ostensible pseudo-columella. A cross-section reveals septa from 

 one side of the theca forming an easy transition with septa from the other side (table I, 

 fig. 3). 



New individuals are formed by splitting. The mother individual increases in breadth 

 and number of septa; it then contracts in the middle and two equally large individuals are 

 formed. 



The colony may have a considerable extent but the trunks are apparently very little 

 thicker in the lower parts than in the upper parts. The colonies seem to prefer to spread 

 out like a fan, the branches dividing on the same plane. This characteristic is common to 

 this form and to the majority of the Octo- and hydro-corals of Faxe.

This species, which is the most common coral species to be found at Faxe and forms 

 the largest part of the coral chalk there, was for many years determined as a Cladocora, 

 because its outward appearance presents many points of resemblance with a Cladocora species 

 from English tertiary formation. Much credit therefore is due to Hennjg, who with extremely 

 insufficient material at his command, (only stone kernels and impressions), was able to see 

 that its internal construction consigned it to the porous coral group, thus determining it as 

 a Dendrophijllia. The same determination had, in the meantime, already been made by 

 Stkknsthup and Forchhammeh, as is proved by drawings of liuit species preserved in the
