man,the most difficult phase of the year,the summer drought. Generally, the length of the captured specimens is 55-69 m™ only slightly below the measurements of green toad specimens originating from other localities of the Great Plains. The bombinator ( Bombina bombin aL.) occurs in the greatest number in the alkali marsh. A smaller amount inhabits also the reeds. The species is less sensitive against the pollution of the water, it can be found also in waterholes defiled by dung. In contrast with the green toad, it is strictly bound to water, be it but a retting-pit. Interestingly, the mating and egg-laying of the bombinator is rather protracted in the alkali area of Kardoskut. Though mating commences already at the beginning of April, single females heavy with eggs can yet be found at the end of May. On 27 May, 1964, I found egg-filled females among bombinator larvae of different phases of development. The general length of the collected specimens lies between 32-36 mm, rather behind the size of our home Bombina bombin a exemplars. I also succeeded to find also the green-coloured variety of the bombinator ( Bombina bombin a 1. var. viridi s MARIÁK). A specimen each was captured on the northern shores, and in a well on the southern side, of the lake. Thus the Fehértó near Kardoskut is the easternmost known locality of the fine subspecies described from the reaches of the Tisza (MARIÁN, 1959). The most interesting frog species occurring in the soda marsh in the spring is the spade-foot ( Pelobates f. fuscus LAÏÏR.). Its grunting voice, calling its mate, can be heard from under the water already during April. After the laying of the eggs, the frog leaves the water and assumes habits similar to those of the green toad on the dry land. The enormous tadpoles can be found in masses also in the water of the hollows near the lake, and in nawypits.
