between the two first lower incisors of a mature man (No. 383). The alveolar cavity of a supernumeral permanent tooth was detected between the right upper 1 st and 2nd teeth of a woman assigned to the senile age group (No. 208). The lack of teeth, eruption disorders and the lack of tooth-buds were observed in a number of cases. The place of the missing right upper 3rd tooth was filled in by the broad and flat rooted upper 2nd tooth in a mature woman (No. 218). Lower right and left 3rd teeth are missing of an adult woman (No. 437). Both upper 2nd teeth of a 13-14 year old child (No. 196) are missing. Their place was taken over by the 3rd permanent teeth while the 3rd deciduous teeth are found in the place of the latter. In the case of another 13-14 year old (No. 199), upper 2nd teeth are missing on both sides, however, root remains of a deciduous tooth were found on the right side. The retention of deciduous teeth was observed in the following cases. A 31-37 year old man (No. 372) retained the upper left Illrd tooth thereby hampering the eruption of the 3rd permanent tooth. In the case of a 20-22 year old woman (No. 182) the right upper Und as well as the two lower Vth teeth remained in place, the right upper 2nd tooth is missing. The right upper Illrd tooth of a 18-20 year old woman (No. 259) was retained, while the right upper Vth was preserved in a 18-20 year old woman (No. 358). The right upper Vth and both the left and right lower IV-Vth teeth remained in place in the case of a 13-14 year old child (No. 11). The lower Vth teeth survived on both sides in the mandible of a 12-14 year old (No. 55). Right and left upper Illrd teeth were retained in a 13-14 year old child (No. 196). In another 13-14 year old (No. 199), the right and left upper Vth was retained and the alveolar cavity of a deciduous root is visible in the place of the right 2nd tooth. The upper Illrd, more exactly the alveolar cavity of its root, was found in yet another 13-14 year old child (No. 306). The other major group of developmental anomalies includes phenomena observed on the postcranial skeleton. Statistically arranged occurrences of these disorders are summarized in Table 4. The phenomena presented in that list are especially interesting in terms of their distribution by sex which suggests that males at Tác more frequently developed bony posterior bridges on the first cervical vertebra and spina bifida as well as sacralisatio. Similarly to the trend observed in other series, the occurrence of canalis intraclavicularis on the clavicle is also more common with men (ERY 1990fl). On the other hand, the variability in the number of vertebrae is more frequent with women, and (with the exception of the relevant trend in the sacrum) discontinuities in the vertebral arch also occur more commonly with females. In the material discussed here the occurrence of os acromiale on the scapula was recorded more frequently with females, although this phenomenon cannot be consid-
