The "exotic nordics" are referred by Coon in several instances but here is an interesting bit:
"Other local series, which represent the coastal regions of northern Portugal rather than the interior, are relatively Mediterranean, and are comparable metrically to Spanish groups. Some of the fishing villages along the coasts, however, contain locally differentiated populations as do fishing villages everywhere; one, Povoa de Varzin in Minho province,126 is distinguished by a slightly greater than usual degree of blondism, broad faces, and broad jaws (bizygomatic = 133 mm., bigonial, 108 mm.). Whence this broad-faced strain is derived is not known. It is curious that the Portuguese, like the Andalusians, are broader jawed than most Mediterraneans, and comparable in this respect to some Berbers.
The apparent homogeneity of the Portuguese, in a racial sense, masks the presence of several brunet Mediterranean strains, as Portuguese anthropologists are well aware. One may distinguish tall Atlanto-Mediterraneans, particularly in the southern provinces, as well as the small, extremely long-headed type found in São Pedro Magodouro. The coarser mesocephalic strain, which dates back to Muge, may also be identified."
Basically Coon had observed the portuguese population and made a generalist approach to it, nevertheless stating that the most common type was the mediterranean one but of several strains and occasional sub-types (dinarics and alpines).
