 of the Cataraqui.

In Crustacea, vol. 2, p. 5. 



The author illustrates one Bohemian Paradoxides and enumerates six 

 other species of tribolites, with citations to the illustrations of other 

 authors. 



Entomolithus paradoxus and Entom. incognitus, pi. 3, fig. 6, have been 

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

 to Tril. hausmanni Entom. paradoxi caput loeve, to Tril. sulzeri. 



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

 36, which is a direct copy of Lhywd's illustration of Trinucleus. The 

 Entomolithus from Andrarum is probably Olenus truncatus. Bromell's 

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

 expansus capite laovi tuberculis nullis (Acta Soc. Eeg. Holm, 1759, Tab. 

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