Burmeister ; * an Austrian naturalist, Vincenz Kollar ; f 
and the acute observer Rathke. \ 
Cuvier, in a note in the second edition of his ‘ Regne 
Animal/ 1830, p. 256, seems to have been somewhat 
staggered in his opinion as to the proper place in the 
system in which the Lernese should be placed. The 
difficulty with him, as to referring them to the Crustacea, 
seems, from this note, to have depended upon the males 
not having as yet been observed. Speaking of MM. 
Audouin and Milne Edwards’s opinion as to their being 
crustaceous, he says, “pour conserver cette opinion, il 
faudrait pouvoir retrouver ces males/’ Had Nordmann’s 
discovery of the existence of the males been known to 
Cuvier, in all probability the Lerneae would not have re- 
mained, as they now do, amongst his intestinal worms. 
In 1837 Kroyer published, in his 4 Tidsskrift,’ vol. i, 
a very excellent paper upon the Natural History of 
Parasitical Crustacea , to which I am much indebted 
for many particulars with regard to their economy and 
habits. And since then, M. Rathke, in vol. xx of the 
4 Nov. Act. Acad. Caes.’ 1843, has still further illustrated 
many points of the anatomy, habits, and manners, of 
some of the animals belonging to this group. 
In this short bibliographical sketch I have not enume- 
rated many original observers of Lerneae after the time of 
Linnaeus; however, their number is considerable. Strom, 
in the ‘Phvsiske og Oeconomisk,’ 1762; Ellis, in the 
‘ Philosoph. Trans.,’ liii; Eabricius, in the ‘ Fauna Groen- 
landica,’ 1780; Miiller, in the 4 Zoologia Danica,’ 1781; 
Hermann, in the ‘ Naturforscher/ xix, 1783; Schrank, 
in his ‘Voyage en Boheme/ 1786; Lamartiniere, in 
the ‘Journal de Physique,’ 1787, and in the Atlas of 
the 4 Voyage of La Perouse;’ Holten, in the ‘Acta 
Danica,’ v, 1799; De la Roche, in the ‘ Bulletin de la Soc. 
Philomath.,’ 1811; Chamisso and Eysenhardt, in the 
* Nov. Act. Acad. Caesar. Nat. Cur., xvii, tli. i.
