REPORT ON THE AMPHIPODA. 501 



rim entire, the other Hijale sensu strictiore (Nicea, Nicolet), with the tclson more or less 

 divided. Professor Wrzes^niowski does not appear to have seen Faxon's paper, dated June 

 1876, on the Fauna of Lake Titicaca, which discusses the genera AUorchestes and Hyale, 

 and also shows that the species of Hyale here described from the fresh-water springs of the 

 Peruvian Cordilleras are not the first of their genus or subgenus known from fresh water, as 

 the Professor supposes. 



To the subgenus AUorchestes, " Telson einfach, ganzrandig," are assigned three new species, 

 " Hijale Jelshii," " Fundort. Siisswasserquelle am Ostabhange der Cordillereu. Pumamarca, 

 8000' iiber der Meeresoberflache " ; "Hijale Luhoiiiirsldi," "Fundort Siisswasserquelle am 

 westlichen Abhange der Cordilleren. Pacaunayo, 8000' iiber der Meeresoberflache " ; 

 " Hyale Dyhowskii," " Fundort. Siisswasserquelle am Westabhange der Cordilleren. Paucal. 

 Montana de Nancho, 7000' iiber der Meeresoberflache." 



In the remarks common to all the species it is stated that, in the side-plates of the last six or 

 five pairs of feet, above the branchite, are inserted cylindrical structures, closed at the point, 

 which are considered to be accessory branchiae (Nebenkiemen). To "Hijale JehMl" he assigns, 

 " Nebenkiemen am 2-5. Fusspaare einfach, von vorn nacli hinten immer an Lange zunehmend, 

 am sechsten Fusspaare am liingsten und doppelt, am siebenten Paare fehlend." " Hijale 

 Lubomirnldi" has "Nebenkiemen einfach, am 2.-7. Fusspaare eingefiigt. Am zweiten 

 Fusspaare erscheinen sie ganz rudimentar, an den zwei folgenden etwas grosser, doch immer 

 sehr klein, an den drei folgenden Fusspaaren liinger als die eigentlichen Kiemen." " Uijale 

 DijhowsJiii" has "Nebenkiemen am 3.-7. Fusspaare, einfach." 



With these species Wrze^niowski would group Hijale (Allarehestes) jncdmcmtensis, Sp. Bate, 

 Hijale {Allorcliestes) microphfhalma, Sp. Bate, Hijale {AUorchestes) hirtipalma, Dana, Hi/alr 

 (AUorchestes) media, Dana, and Hi/cde (AUorchestes) ruhricornis, Stimpson. 



To the subgenus Hijale, " Telson mehr oder weniger gespalten," are assigned the new species, 

 " Hijale Stokriiani," " koine Nebenkiemen," found under stones on the sea-coast, and as its 

 nearest relations, Hyale (Nicea) ijlumicoriiis. Heller ; Hijale (Nicea) fasciculata, Heller ; 

 Hyale (Nicea) nudieornis. Heller ; Hijale (Nicea) macromjx, Heller ; Hijale (Nicea) 

 camptonijx. Heller ; Hyale (Nicea) sclimidtii, Heller ; Hyale (Nicea) rudis, Heller ; Hyale 

 (Orcliestia, AUorchestes) perieri, Lucas, Grube ; Hyale (AUorchestes) imhricata, Bate, 

 Stebbing.

The name Goplana is said to designate in Polish a water nymph. The genus is thus defined : — 

 Upper antennas longer and stronger than the lower and provided with a short accessory 

 flagellum. First and second gnathopods subcheliform, subequal. Last uropods one- 

 branched. Telson simple, emarginate. The three last pleon-segments coalesced. 



The last character is said to be its chief distinction from Cramjonyx, Sp. Bate. A description 

 of the species and its habits follows, containing some sufficiently remarkable particulars. 



On the second gnathopod and first peraeopod of both sexes on the front rim of the fleshy part of 

 the side-plate are seated a pair of cylindrical accessory branchiae ; to the fourth and fifth 

 perseopods and to the front rim of the first abdominal segment similar but simple accessory 

 branchiae are attached. They are entirely wanting on the second and third peracopods. [In 

 the original some errors have crept into the printing, which I have ventured to correct 

 according to what I suppose to have been the author's intention.] In tlio male from the
