in Greenland. In the mouths of the large rivers, it ascends rather high, over BaBel in the Rhine, to Ennezat in the Loire, to Sierre in the Rhone, to Cracow in the Vistula, and to Narewka in the Narew. As regards the Danube, it lives only in ite delta, the same as in the other southern Russian rivers

. Earlier authors thought that the sticklebacks are entirely absent from the water system of the Danube, as stated, e.g., by MECKEL and KHER /14/.STEINDACHNER was the first /23/ to Bhow its near ally from the tributaries of the Danube, namely from the Save and from some marshes along the Negotin, PungitluB pungltlus L.

Gaeterosteua pungitlus L./, but he later rectified hie erroneous datum /24/ to Pungltlus platygaeter /KESSLER/ /Gasteroeteus platygaster L./. Concerning Gasteroeteus aculeatus L.

, the view, that it is absent from the Blach Sea and the Basin qf the Danube, still held good. Then ANTIPA /1/ demonstrated that it can be found in the Black Sea. With reference to the occurrence of the stickleback in our home literature, authors took different standpoints, according to their notions. REISINGER /1830/, HERMAN /15/, and UNGER /26/ listed it in our home fauna, while HECKEL and KNER /14/, and VUTSKITS /31,32/ excluded it. The explanation of these contrary views lies in the fact that authors who considered this species as a member of our home fauna, hoped to show it from the Poprad in the North, as a species common in the North Sea and the Baltic Sea, known everywhere in Germany. Those opposing this view, after having repeatedly studied the Poprad, did not accept this possibility in the lack of an actual specimen validating it. Two explanations may come into account on how this small fish found its way into the Budapest stretch of the .anube. One of them, and in my opinion the more probable, is • iát it arrived from the lower reaches of the river. ANTIPA /1/ mentions the delta of the Danube as one of its stations;
