There were about 32 septa in 1 incomplete and 3 complete cycles. Only the septa of 

 the 2 first ordines reached the center, the others protruded but slightly from the edges 

 of the theca. This is known from the stone kernel by the fact that the interseptal fillings 

 lie adjacent, 2 and 2, with deep furrows between the separate groups and slight furrows 

 between the fillings in the same group. This gives the stone kernel a two-serried (bi-seriate) 

 appearance. 



Locality: Senone. The zone with Scaphites constrictus: Cerithium chalk at Stevns Cliff.

From the cerithium chalk from Stevns Clifî we have a couple of stone kernels and the 

 impression of a coral, so characteristic that they permit determination. 



The impressions are very long; the longest is 28 mm with a diameter of about 8 mm. 

 The impressions show that the coral was long, shaped like a worm with many bends. The 

 theca was thin, covered on its outer surface with quite prominent costae, broken by numerous 

 epithecal lines running in a transverse direction, thus dividing the outer surface of the coral 

 into many small quadrilaterals. No actual smooth epithecal covering was seen. 



The fragments found were not sufficient to determine whether the coral was attached 

 or free. 



The stone kernels show traces of dissepiments, for they are short, and, measured by 

 the impressions, only a fraction of the entire length of the coral. There were about 30 septa, 

 that is to say, 4 ordines in 1 incomplete and 3 complete cycles. 



The lateral surfaces of the septum were covered with rows of sharp granulations.

19. Parasmilia parva, n. sp. 



Table IV. Figs. 13—16. 



This little species is easily recognised by its external appearance. It seems to be 

 common to all the Danien strata. 



Its form is obovate-conical, seen best in young specimens. When older it shows an 

 inclination to irregularly curved elongations. It adheres by means of a small root extension. 



The largest specimen known measures 15 mm in length and has a diameter at the edge 

 of the calyx of about 5 mm. The majority of the specimens are much smaller. 



The theca is dotted on its outer surface with thin costae. These are sometimes broken 

 olT, forming a row of small ridges. 



The calyx is deep. 



The septa protrude but slightly beyond the edge of the calyx and, as a rule, close to the 

 thecal tissue, they sink deep into the bottom of the calyx. Here their inner edges unite, forming 

 a pseudo columella the upper portion of which is just visible. The septal edge is wavy. The 

 lateral surfaces of the septum are covered with rows of quite conspicuous granulations.
