138 CAEL BOVALLIUS, AMPHIPODA HYPERIIDEA. I. 2. HYPERIID^. 



Hyperia. 



inferiorlyy> etc, excludes just the type-species Hyperia medusarum, and some other 

 good species from the genus. Spence Bate also wrougly attached as synonyms to Hy- 

 peria the genus Tauria, Dana, and Metoecus, Kroeyer. 



In 1868 he and Westwood gave diagnoses of Lestrigonus and Hyperia almost in 

 the same terms as in 1862 though with an important alteration with regard to the first 

 pair of perajopoda, saying fifirst pair nearly simjAe, the second complexly subchdate». They 

 had the same suspicions as to the relation of Hyperia and Lestrigonus which occurred 

 to Spence Bate in 1862, but still they maintained Lestrigonus as a genus by itself. 



A. GoÉs in 1865, was the first ^) who took Lestrigonus to be synonymous with, 

 and a male form of Hyperia. He was followed in 1869 by A. Merle Norman, and 

 in 1870 by A. Boeck who gave a good diagnosis of the genus Hyperia in its true 

 limitation^): 



» — — — Antennae perfecta;, superioris pedunculo perbrevi, Sarticulato; flagello apud ma- 

 rem multiarticulato et longiore, apud feminam perbrevi, articulis carenti.» 



»Pedes Imi et 2di paris manu subcheliformi carentes; carpo in angulo inferiore posteriore 

 in calcem brevem producto; manu apicem versus attenuata. Pedes 3tii et 4ti paris articulo 4to 

 perbrevi, non dilatato. Pedes trium pariuin ultimorum breves, invicem ferme eadem longitudine; 

 articulo Imo subdilatato.» 



As a synonym for Hyperia he erroneously cited Tauria, Dana. In 1872 he 

 repeated the above diagnosis, saying expressl}? that the difference between Hyperia and 

 Lestrigonus is only sexual, the latter being the male of the former. 



Claus gave in his »Grundzlige der Zoologie», in 1875, the foUowing generic de- 

 scription of Hyperia: 



»Beide Antennenpaare beim Weibchen ziemlich kurz, beim Männchen (Lestrigonus Edw.) 

 mit longer vielgliedriger Geissel. Die beiden vordei-n Beinpaare schmächtig und mit scliwacher 

 Greifhand. Die drel hintern Beinpaare von gleicher Gestalt.» 



In 1877 Streets") strongly argued that Hyperia and Lestrigonus were different 

 genera, misled by the discovery of what he supposed to be a new species of Hyperia, 

 with male; and female having short uni-articulate flagellum of the first pair of antennse. 

 The animal in question, however, belonged not to the family Hyperiidte but to Cyllo- 

 podidce (see above p. 19). 



In 1885 Carus gave a short diagnosis of Hyperia, probably translated from that 

 of Claus in 1875; it runs: 



»Hyperia, Lätr. ($; o^ Lestrigonus, M. Edw., incl. Metoecus, Kr.) Antenna utraque in 9 sat 

 brevis, in (^ flagello longo pluriarticulato ; pedes I. et II. graciles, manu debili prehensili, 

 pedes tres posteriores forma asqua.» 



') In fact Fr. Muller had pronounced tlie same opinion the preceding year speaking about his new 

 species Hyperia {Hijperoche) Martinezii, (see above p. 108), but as this animal does not belong to the genus 

 Hyperia I cannot cite him here. 



-) The first part of the diagnosis here quoted is with full right placed by Boeck in the diagnosis of the 

 family Hyperida and cited here only to show that he fully uuderstood the question.
