Notes 



I By ANGELIN on p. 18 ascribed to the genus Nileus DALM. Compare BROGGER 1882, p. 61. 



See T. Wegelini. 



Identical with T. fractus BARR. Compare TORNQUIST 1884, p. 89. 



By BARRANDE (1852, p. 42) united with the genus Acidaspis MURCH. 

 Compare LINDSTROM 1885, p. 56.) 



\ See the preceding note. 



According to TORNQUIST 1884, p. 84, identical with Tr. seticornis His. 

 ANGELIN'S Ba is surely a misprint for Da. 



Compare J. G. ANDERSSON 1893, p. 532, and SCHMIDT 1894, p. 71. See also Tr. affinis. 



BEYRICH (1845, p. 31) described Trochurus speciosus n. g. et n. sp. (head and tail). Later he found that 

 the head belonged to Staurocephalus Murchisoni BARR. and finding the peculiarities of the tail in 

 question well exhibited on Arges armatus GOLDF., he withdrew the name Trochurus and classed 

 the tail with the genus Arges (BEYRICH 1846, p. 8). BARRANDE and other authors considered Arges 

 as a mere synonyme of Lichas. LINDSTROM (1885, p. 56), however, held forth that the forms ascri- 

 bed to Arges, as showing peculiar characters, ought to be kept apart as making a genus of its own; but as 

 the name Arges was preoccupied for another crustacean he proposed to revive the name Trochurus.
