634 LINDSTRÖM, ON THE »CORALLIA BALTICA» OF LINN^US. 



1887 Stauria favosa Id. List of Fossil Faunas of Sweden, 

 II, 21. 



1894 Stauria astraeiformis Weissermel Korallen d. Silur- 



gesch. Ostpreussens p. 612. 



Columnaria sulcata Lonsdale, Russia I, p. 601, pl. A. f. 1, 

 by M. Edw. & H. considered as identical with Stauria, is quite 

 different and belongs to another generic type. Nor can the 

 Columnaria sulcata of Eichwald be congeneric with Stauria. 

 The »notse characteristicffi» which Linn^us ascribed to this fossil 

 leave not the least doubt that it is the same as Stauria astraei- 

 formis of MiLNE Edwards and Haime. There does not indeed 

 exist any other Gotlanc^ coral exbibiting the four large septa. 

 It was also the opinion of the said celebrated authors, but 

 surely it was the circumstance that Linn^us in the twelfth 

 edition of Syst. Naturse p. 1275 united with it exotic recent 

 forms from the Indian Ocean that induced them to form a new 

 name for it. He refers it, however to the figure and description 

 in Amoen. AcademicaB. He, as we know, sometimes mingled the 

 fossil Baitic corals with recent ones, which is explained by the 

 circumstance, that he believed that the corals which had become 

 extinct in the Baitic, had migrated to warmer seas. None of 

 the recent corals mingled up with the fossil M. favosa is pro- 

 vided with the characteristic four large septa and they belong 

 probably to the genus Prionastrsea. Now, if a new name is to 

 be given, it should be to the recent species, which have been 

 confounded with the original »favosa», nor is it necessary to 

 abolish this name altogether and create new specific names for 

 all: for the oid species and for each of the new ones. I there- 

 fore think it most advisable to keep the Linnean name for the 

 fossil which originally received it and still had it in the tenth 

 edition of Syst. Nat., that basis for the future nomenclature, and 

 to abolish the new name. 



P. 27, N:o IX. Millepora ramis vagis; punctis sparsis fig. XII. 



There is no further mention made of this coral in the låter 

 works of LiNN^us.
