The posteroloph connected with the posterior ridge of the metacone and linguelly formes a small spur. On the scatter diagram (Fig. 4) we can see 4 small sized molars different from the main mass of the Meydan material. M 2 (Flg. 5). The molar is 4 rooted. On the anterolabial side there is a well developed cingulum separated by a ditch from the paracone. The 4 main cusps form an X in the center of the tooth crown. The protocone-parecone and the metacone hypocone pairs are divided by a ridge of the lingual and labial margin. Between the paracone and the metacone in the sinus there Is a rare conulet: the mesostyle (MSST). Other accessory ridge is the Posterolophule (PLL.) between the posteroloph and the metacone. The distribution of the morphotypes is the next! type no. 4 1 no accessory elements 2 PLL + 3 PLL +, MSST • On the scater diagram (Fig. 6) there is only 1 tooth which is undisputably the member of the smell sized group and there are 4 problematic molars on the lower margin of the main mass. One of them is from the max. fr. no. 15. where the M 1 is small sized too. But in the max. fr. no. 51. there are small M 2 and normal measured H 3 together. M 3 (Fig. 7.). The molar is 3 rooted. Among the 4 main cusps of the tooth crown the hypocone and the metacone is reduced. The accessory elements of the tooth are the lingual anteroclngulum (LAL), the extra ridge between the paracone and the anterobuccal cingulum (ALD), and the reduced posteroloph (PL). The morphotypes are distributed as follows: type 2 LAL +, AL0-, PL+ 3 LAL -, AL0-, PL+ 4 LAL -, AL0-, PL5 LAL -, ALD-, PL6 LAL -, AL0+, PL+ On the scatter diagram wa can recognize 2 small sized molars. m 1 (Fig. ?.). The molar is 2 rooted. The anteroconld is divided in two by a depresion which is deep on the unworn teeth. Before the anteroconld, on the oral surface of the molar there is an accessory conulet, the preanteroconid cingulum (PAC). The ridge coming down from the anteroconld connected In reversed Y-shape with the anterior arms of the protoconid and metaconid. On the majority of the teeth between the protoconid and the endoconid there is the mesolophid (ML). This is reduced and fuses with the metaconid. On the lingual edge of the crown between the metaconid and the endoconid there is an accessor 1c conulet: the mesostylid (MSSTO). no. s 2 3 35 51 29 42 2 3 1 1 è) 100 / 113
