Phronima is as a genus by itself the oldest in the whole tribe being instituted 

 by Latreille as early as in 1802 in his »Histoire naturelle generale et particuliere des 

 Crustaces et Insectes», third volume. He gave the following diagnosis: 



»Antennes apparentes au nombre de deux, presque setacees, des trois articles. Des palpes 

 saillans, setaces. Dix pattes; les quatre anterieures et les quatre posterieures terminees par une 

 piece conique, un pen arquee; celles de la troisieme pair les plus longues, et terminees par une 

 main ayant deux pinces. Dei'niers anneaux etroits: plusieurs stylets alonges, articules et bifides, 

 a l'extremite du corps. 



Corps mou. Tete fort grande. Animal vivant dans un corps ovalaire, transparent, presque 

 gelatineux (Cadavre d'un Beroe?)» 



In the sixth volume of the same work he gave a close description of the type spe- 

 cies Phronima sedentaria, Forskal. 



In 1806 he characterized the genus with the following words: 



»Pedes decern; tertio pari longiore manibus didactylis.» 



In the same year Dumeril gave an extract of Latreille's description. 

 In 1815 Leach gave the following diagnosis: 



nCaput magnum, nutans; antenna; biarticulatas, articulo primo parvo. Thorax 7-articulatus, 

 segmentis omnibus pedigeris. Pedes compressi;, paria duo antica articulo antepenultimo ad 

 apicem processu foliaceo instructa; articulo penultimo apice bifido, ungue minuto termiuato: paria
