1865, Heller, Camil. 



Kleine Beitriige zur Kenntniss der Siisswasser-Ampliipoclen, Mit 1 Tafel : 

 (Taf. 17.) (Aus den Verliandlungen d. k. k. zoologisch-botanisclier Gesellschaft in 

 Wien [Jahrgang 18G5] besonders abgedruckt.) 



The new species O-irliedia mvimana is here described and figured. It was taken on Mount 

 Olympus in Cyprus, at a height of 4000 feet by Dr. Kotschy. The new species, "Gammarus 

 Veneris" wae also taken by Dr. Kotschy in Cyprus, 50 feet above the sea. This species is 

 said by Heller to be intermediate between Gamiiircnis warinus and Gammarus piilex. In 

 " a review of the hitherto known South European fresh-water amphipods," he says that 

 " they all belong to the genus Gammarus Fabric." He arranges them as follows : — 



" A. First gnathopod somewhat larger than the second, telson simple, undivided ; third uropod 

 with a single ramus. (Subg. Crangonyx, Sp. Bate.) 



"1. G. recurvus. 



" A A. First gnathopod not larger than the second, telson deeply split, or double ; third uropod with 

 two rami : — 



"a. First gnathopod almost as large as the second, eyes rudimentary, the three last 

 segments of the pleon without bundles of spines, the outer ramus of the third 

 uropod bi-artieulate. (Subg. Niphanjus, Sch.). 

 " 2. 6r. puteanus. 



" b. First gnathopod smaller than the second, eyes well developed. The three last pleon- 

 segments with bundles of spines, the outer ramus of the third uropod uni-articulate. 

 (Subg. Gammarus, Sp. Bate). 



" a. The three first pleon-segmeuts prolonged backwards to a pointed spine- 

 tooth. 



"3. G. Boeselii. ' 



" p. The three first pleon-segments straight behind, without spine-tooth. 



" t The outer ramus of the last uropod only a little longer than the 

 inner. 



" 4. G. pulex. 



" tt The outer ramus of the last uropod much longer than the irmer. 

 "5. G. imngens." 



These divisions are founded on 1. Crangonyx recurvus, Grube ; 2. Niphargus {Gammarus) 

 puteanus, Caspary, with which Heller unites Niphargus siygius, Schiodte, and Niphargiis 

 aquilex, Sp. Bate ; 3. Gammarus roeselii, Gervais, identified with Squilla fluviatilis, Eosel, 

 and Gammarellus pulex, Herbst ; 4. Gammarus pulex, Desmarest, identified with Gammarus 

 fluviatilis, M.-Edwards, and 5. Gammarus pungens, M. -Edwards. Of this last he says that 

 it closely agrees with his own new species Gcommarus veneris, only that, according to 

 M.-Edwards' short description, Gammarus pungens appears to have the inner ramus of the 

 last uropod quite rudimentary. Of Gammarus veneris itself. Heller thus describes the last 

 uropod, "ramus interior pedum sexti paris postabdominis exteriore multo brevior, ramis 

 hirsutissimis." Gummarus roeselii, he says, " lebt in tiefen stehenden oder schwach 

 fliessenden Gewiissern. Ich kenne ihn aus der Umgebung vou Salzburg, Wien und Ofen, in 

 Tirol habe ich ihn noch nicht angetroffen,"
