Amiphipoda balcanic^a, 99 



Gakbini in Zool. Anzeiger is idenlical with the Carinogam- 

 marus roeselii (Ger v.) 



3. Carinogmnmarus argaeus (Vávra) 

 (Pí. L, 3; text fig. 18.) 

 described by Dr. V. Vávra {Gammarus argaeus Yavra 1902) 

 is coming from this group. But it has very small eyes, pro- 

 podits and carpopodits of the 1^^ and 2"^ peraeopod are wi- 

 thout long setules. Dorsal spinules on the uropod seginents 

 are as follows in the schéma on page 40. 



The 3^'^ uropod with a very slender terminal-segnieiit 

 of the exopodit and with a few long setules. 



y>G.'< argaeus var. hrachyurus (Vávra) is in my opinion 

 a specimen with regenerated uropods. 



b) The group with an arched car i na: 



4. C ar ino gammarus tJioni n. sp. 

 (PÍ. I. 4; text fig-. 19, 20. 21.) 



Arched carina on the 6'*^ and 7^^ peraeon segment and 

 the 1®^ — 3^^ pleon segments. 



Found by f Dr- K. Thon in the lakes oť Herce- 

 govina: Modro Oko, Deransko and in the springs 

 Slano vřelo and Lukavac. 



5. Carinogammarus scutarensis n. sp. 

 (PÍ. L. 5, 5a2, 5p3-5; text fig. 22, 23.) 



Eyes large reniform. Conus excretorius on the antennal 

 glands as long as headand grows crooked at the basis. The 

 last peraeon segments and the first three abdominal segments 

 with an arched dorsal carina. 



Lives in the lake Scutari (légit Mrázek) at llie 

 mouth of the river Rybnica, with C. triacanfhus. The long 

 conus excretorius is a very rare phenomenon, and ])erhaps 

 a mutation, which is fixed by heredity. 



6. Carinogammarus pungentiformis n. sp. 

 (Pi. I., 6.) 

 Only pleon segments with an arched carina. 

 Setules very well developed arid frequent.
