Genus Pseudohealdia Gründel, 1964 Pseudohealdia acuticauda sp. n. (Pl. I: 6) Derivatio nominis: After its acute posterior end. Locus typicus: Hárskút, Közöskút Ravine Stratum typicum: Carixian, Ibex Zone, sample No. 1. Diagnosis: Both valves terminate posteroventrally in a short but strong acute cauda. Description: The anterior outline is very asymmetrical, its upper part is fairly, lower part is considerably rounded. The dorsal arch is nearly symmetrical, its posterior part is suddenly curved to the stright posterior outline runnig at right angles to the ventral one. There is a short and strong caudal process at the connection of the posterior and ventral outlines. The ventral outline is fairly convex. On the right valve the upper part of the anterior outline, the dorsal outline and the posterior outline are less rounded, they are somewhat "trapezoidal". There is a short cauda at the posteroventral corner, the ventral outline is fairly sinuous. The anteroventral part of both valves are fairly projected. The left valve overlaps the right one except its posteroventral and anteroventral ends. Comparison: Pseudohealdia nasuta (Drexler, 1958) is similar in shape. Its anteroventral projection is more distinct, the posterocentral spine is smaller and not cauda-like. Dimensions: L = 0.77 mm, H = 0.53 mm, L/H - 1.45 Material: 2 specimens. Familia Saipanettidae McKenzie, 1968 Genus Cardobairdia van den Bold, 1960 Cardobairdia harskutensis sp.n. (Pl. I: 7-8, Pl. II: 1-2) Derivatio nominis: After the locality Hárskút. Locus typicus: Hárskút, Közöskút Ravine. Stratum typicum: Carixian, Ibex Zone, sample No. 1. Diagnosis: Stubby form with posterodorsal depression and a very fine reticulation on the lateral surface. Description: The anterior outline of the left valve is broadly and somewhat asymmetrically rounded, the dorsal outline is from 0.1 to 0.7 of the length broadly rounded, than it is straight. After a break the posterior outline is asymmetrical, with a break at the level of the 2/3 heighth. The ventral outline is broadly rounded. Some large specimens have more symmetrical and narrower anterior and posterior outlines and also more symmetrical and very broadly rounded dorsal and ventral outlines. There is a strong depression on posterodorsal part and a weak at the anterodorsal corner. In case of very fine preservation there is a fine reticulation visible on the lateral surface. The anterior and posterior outlines of the right valve is nearly symmetrically rounded, the dorsal arch is very low, the ventral outline is straight.
