LERNEADJE. 315 



Burmeister ; * an Austrian naturalist, Vincenz Kollar ; f 

 and the acute observer Ratlike. | 



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 tlie proper place in the 

 system in Avhich 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 Lernese would not have re- 

 mained, as they now do, amongst his intestinal worms. 



In 1837 Kroyer published, in his ' 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 

 ' Nov. Act. Acad. Cses.' 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 1 have not enume- 

 rated many original observers of Lernese after the time of 

 Linnaeus; how^ever, their number is considerable. Strom, 

 in the 'Physiske og Oeconomisk,' 1762; Ellis, in the 

 'Philosoph. Trans.,' liii; Fabricius, in the ' Fauna Groen- 

 landica,' 1780; Miiller, in the ' 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 '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
