. In almost all measurements greater than the other specimens from the Pliocene of Hungary. Obviously and decidedly greater than the Miocene Rh. delphinensis GAILLARD. In size it approaches the Miocene Rh. lemanensis. If the mandibular molar row 10 in Rh. lemanensis

, then the combined premolar length is 4. 1. In present species it is 3. 96 (the means of the two measurements were used). The lower C crosssection is rather long orocaudally (decidedly less pressed than in recent species). P

2 moderately long orocaudaUy. Pg almost fuUy extruded from toothrow, however.it is comparatively big and in 30% of the cases there is a slight diastema between P

2 and P

4

. In one specimen the Pg is twice as big as in others. P4 is in some cases squarish in cross section and as long aa wide, in other specimens it has oblique frontal margin (outer margin is shorter than the the inner one) and in these specimens the inner and outer margins are approaching orally. The palatal bridge is decidedly longer than those of Pleistocene and Holocene forms, however, it is similar to that of Rh. macrorhinus TOPÁL. Upper C cross-section long and wide. Its labial margin is without any impression prosteriorly

, so it is convex or straight. Its talon is well developed on lingual side posteriorly and even it might also reach the anterior margin of P

4

. P

2 more or less pressed orocaudally. In most of the cases about half in the line of toothrow and there is a distinct diastema between C and P

4

. The talon of molars, especially that of Ml is well developed, back- and inwardly directed. Rhinolophus estramontis n. sp. Derivatio nominis

. Named after another, local name: "Esztramos" of the Osztramos Hill, NE Hungary (aUegedly with Latin origin from extra Möns); likevise the nomination of horizon Estramontian (JÁNOSSY , 1972). Stratum typicum and locus typicus

. Younger stage, Estramontian Horizon of Middle Pliocene from Osztramos Loc. If, NE Hungary. Diagnosis. A large species of Rh. ferrumequinum group. Size near Rh. kowalskii, with more progressed premolars than in that species. Holotype

. Left mandible without angular process and with full dentition, except Ij. In the coUection of the Palaeontological Department of the Hungarian Natural History Museum (Inventar No. V. 79. 191). Measurements of holotype. Mandibular length: 16. 25; C-M

: 0.13-0.32. Description and comparisons

. Although the measurements of this species are near those of Rh

. kowalskii, stiU, it is in many respects slightly smaller than that species, (see, ùgures 5: B, D- 7: A, B, C, E; 8: A, B). In the contrary, it has rather great values for upper C cross-section lengi-i , M

3 length, Mj length, M^-Mg length, with greater values or means than in Rh. kowalskii (see, figu±e = 5: A; 6: B, 8: C). If we take the mandibular molar row as 10, then the combined premolar-row '.ength is 3. 92 in holotype mandible. Thus its dentition seems to be somewhat more evolved than thai 'Rh. kowalskii from Podlesice and expressedly more evolved than Rh. lemanensis from the !.. 7..'. * "
