though rarely, that epecimene can be met with far from the ueual habitats of the specieB. In the annihilated ICHTHYOLOGICA1 COLLECTION OF THE HUNGARIAN NATURAL HISTORY MUSEUM, there was a specimen collected in the Tisza, at Szeged, on 14 March 1918. In the 'thirties, both the brook and the rainbow / Salmo irideua GIBB./ troute were captured several times in the Balaton. Thua, A.SZABADOS /12/ mentions a Salmo irideus specimen caught at Tihany /8 June 1937/, K. LUKÁCS /7/ a Salmo trutta fario from between Szárszó and Szemes, in January 1938 /this specimen was given to the ICHTHYOLOGICAL COLLECTION OF THE HUNGARIAN NATURAL HISTORY MUSEUM/, and the same author /8/ also states that a Salmo Irideus was captured at eaiacBony in February 1938, and a brook trout from Keszthely i£~-y*e beginning of the same month. The explanation of thsi pelativeijF^requent occurrence of the two trout species in thfBalaton is the fact that, at that time, both fish had been bred in the fisheries of Csopak and Lesencetomaj , from where they have reached the Balaton indubitably by the Nosztor, that is, the Lesence, brooks. VUTSKITS /15/, who compiled the chapter on fishes for the FAUNA REGNI HUNGÁRIÁÉ, did not list Salmo trutta m. fario from the Danube, and, ae far ae I know, this species had not been shown from this river yet. Its occurrence in the Hungarian reaches of the Danube is in any case a real rarity. A specimen was found luckily, when looking over the haul of fishermen on 1 April I960. At this time, they were working the reach between Zebegény and Visegrád. The brook trout, caught in their net, found its way into the ICHTHYOLOGICAL COLLECTION OF THE HUNGARIAN NATURAL HISTORY MUSEUM. Cottus goblo LINNÉ Cottus gobjo is also an inhabitant of the trout-level, but it also occurs at lower gradée. Thus, it was &hown also from the Hungarian reaches of the Danube, but, according to our present informations ,it is a rare species here. VUTSKITS
