1 molars of Collimys dobosi. — 1 = 2003.4., morphotype AaOv; 2 = 2003.15., morphotype AaOw; 3 = 2003.13., morphotype Aalv; 4 = 2003.36., morphotype ApOv; 5 = 2003.38., morphotype ApOw; 6 = 2003.20., morphotype Aplv; 7 = 2003.50, morphotype Aplv; 8 = 2003.37, morphotype Aplw. The metalophule is simple, posteriorly converged and connected to the posteroloph (v variation in Table 1 and in Figure 8) In 14 molars (19%) the metalophule bears a short anteriorly directed extra enamel ridge (W variation in Table 1 and in Figure 8). A very similar element was found in the tooth crown of Collimys primus (KÄLIN & ENGESSER, 2001, abb. 36 f). A weekly developed mesostyl is found in 21 molars (26 %) but it is missing in 59 specimens (73 %). Amongst the Ml molars the ApOv configuration is the most frequent (23 specimens). This represents the coexistence of the following features: uninterrupted anteromesoloph + presence of protolophule II. + mesoloph does not reach the buccal margin + simple metalophule. The type Aplv is subdominant (16 molars). It differs from the ApOv type with the mesoloph reaching the buccal margin of the tooth crown (Figure 8). Figure 8 — Schematic morphotype-system of Collimys dobosi M

1 molars and the distribution of the morphotypes. — A — anteromesoloph long and uninterrupted; B — anteromesoloph interrupted; a = protocone and paracone are connected by protolophule I.; b = protocone and paracone are connected by protolophule II.; X = protolophule I. and II. are equally developed; 1 = mesoloph reaches the buccal margin of the tooth crown; 0 = mesoloph does not reach the buccal margin of the tooth crown; V = metalophule is simple; W = metalophule bears accessoric enamel ridge.
