In Bosnia, we come to the famous site of Glasinac, 21 where a comparatively large series of relatively late Illyrian remains contains again a mixture of types. The majority of the skulls are long headed and these show the same mixture of Danubian and Corded elements which we have already seen at Hallstatt itself. A few of the individual crania are very large, and reproduce the Corded prototype quite accurately. The brachycephalic skulls, although in the minority, are numerous enough to permit one to determine their racial affiliation with some accuracy. Almost all belong to what might be called a modern Dinaric racial type. The skulls are moderately large with flattened occiputs, straight side walls, rather broad foreheads, and a very prominent nose, in the one instance in which the nasal bones were preserved. 22 The jaws are very broad with an excessive bigonial diameter, but not noted for their depth.

This is the first occurrence of crania of this type in the Dinaric Alpine region in any considerable numbers. We have already seen, however, that this same type had entered these mountains by the beginning of the Bronze Age, in connection with the eastward movement of the Bell Beaker peoples. The round-heads at Glasinac and in Carniola may have been the descendants of these Bell Beaker refugees.

Metrically, these brachycephalic crania resemble the Bronze Age series from Cyprus, but are, on the whole, a little larger. They fall, as a matter of fact, into an intermediate position between the Cyprus series and the Bell Beaker group from the upper Rhineland, but in morphology are identical with both. There is no doubt that we are dealing in this instance with a form of Dinaric which anticipates the modern population of Bosnia.
