i) Thunberg's article was published as N°. 30 in 

 the first volume of the Physiograph. Selsk. Hand- 

 LiNGAR which was edited between 1776 and 1786. 

 Prof. E. LoNNBERG of Stockholm was kind enough 

 to inform us, that part 4 of the first volume contained 

 the articles 28 — 33 and was ready May 1786. It is 

 therefore probable, that Thunberg's article (N^. 30) 

 appeared already in 1785 or even earlier and that 

 therefore his name S. tetragonus is prior to 5. biacu- 

 leatus of Bloch, as one is inclined to suppose in 

 accordance with the nomenclature and synonymy of 

 Linne-Gmelin. But this can not be proved as, according 

 to the kind information of the present secretary of 

 the Physiographic Society of Lund, the "Protocols" 

 of the Society contain nothing about the article 

 of Thunberg.
