The XX"' node has a short, deformed cirrus in the same radius 

 as I Br = 12. The XXI and XXII nodes have no cirrus in this radius. 

 The infranodal facet of the last node is not newly broken, but oxer- 

 grown by some Bryozoan colony, which also occurs in the empty 

 cirrus-facets on the XXP' and XXIP' nodes. The intei'nodal joints at 

 the XX**" node are a little shorter than in the other parts of the stem. 

 The I Br-series with 4 and 12 components stand alongside of each 

 other and are noi'mally directed upwards; the bases of the other ones 

 are horizontally directed and 2 (the 4"' and 5*'') are a double-arm 

 standing on 4 radial small ossicles. Thus the whole crown turns, as 

 if it had been lying on the side on the 4"' and 5"' radius and by the 

 continued growth had tried to rise into a vertical position. J^issibly 

 one might infer from what is said above (hat the crown \\as injured, 

 when it was on the present XX**" node and that at the same time the 

 stem was broken at the present XXX"'(last) node. If this is the 

 case the abn(»rmiil tlivei-gences are to be explained by this accident. 



In some specimens there occurs a large Mijzostonm. probably
