On the CoEALS of the Teiassic, EniETic, and Kossen Strata of the 

 Alps. By Professor Retjss. 

 [Proceed. Imp. Acad. Vienna, July 23, 1864.] 

 The corals of the Alpine Trias and of the Ehaetic beds, although of 

 extremely frequent occurrence in some strata (as in the Dachstein 

 or Lithodendron-limestone), are still but very imperfectly known, 

 owing to their bad state of preservation. All the determinations 

 hitherto established, some of which were made when even recent 

 corals were very imperfectly known, require to be thoroughly revised : 

 and, above all, those of the Palaeozoic genera Cyathoj^hyllum, Cateni- 

 jpora, Syrinriopora, Calamojyora, and Chcvtetes, which seem to have 

 no genuine representatives in the Trias and the Rhfetic beds. The 

 general aspect of the Upper Alpine Triassic Corals is rather uni- 

 form ; they include about thirteen species (still wanting revision) of 

 Mo.itlivaltia, and seven species of free-branched Astrceidce (Clado- 

 philllia, BhahdophiiJIia, CalamophyJlia, and Thecosmilia). Next to 

 them come two or three species of Latomceandra ; Thavxnastrcea, 

 with five species, still wanting rigid determination, is the only genuine 

 Astraean having some influence on the general type of this fauna. 

 The species of Isastrcea and Astrcea are very isolated, as also is a 

 Goniocera, the only representative of the Cladocoracece. One Flet- 

 cheria and one CoccophyUum (a new genus) are the only undoubtedly 

 tabulate Corals connecting the Triassic fauna with the Palaeozoic. 



The Rhaetic Anthozoa, although less abundant in species, are more 

 diversified than those of the Trias ; but their determination is still 

 more uncertain, especially as to the few species occurring in the 

 Dachstein. Not one of the many specific names appKed to the
