The author illustrates one Bohemian Paradoxides and enumerates six 

 other species of tribolites, with citations to the illusti'ations of other 

 authors. 



Entomolithus paradoxus andEntom. incoguitus, pi. 3, fig. 6, have been 

 referred by Sternberg to Tril. tessini. Entom. expansus caput truncatus, 

 to IVil. hausmanni Entom. paradoxi caput Ifeve, to Tril. sulzeri. 



The last reference is doubtful. Born cites Wilken's figure Tab. 7, fig. 

 .36, which is a direct coj^y of Lhywd's illustration of Trinuclexis. The 

 Entomolithus from Andrarum is probably OJenus truncatus. Bromell's 

 woodcut on p. 77 is given as a reference for this species. The Entom. 

 expansus caj^ite Ifevi tuberculis nullis (Acta Soc. Eeg. Holm, 1759, Tab. 

 2, fig. 1), from Bohemia is a doubtful species.
