For Ateles, Cynocephalus and Cercopithecus the data were derived 
from individuals of ditferent species. The species of the two former 
genera are not accurately known to me, of Cercopithecus the skulls 
belonged to the species: albogularis, patas, talapoin and Campbelli. 
The small skulls of Hapale belonged to individuals from the environs 
of Paramaribo; it would be difficult to assert whether they all belong 
to one species. Also of Hylobates I did riot know the exact species; 
two of them originated from the south-western part of Borneo 
(probably H. concolor), the three remaining ones from Deli on Sumatra 
(probably H. agilis). But it must be borne in mind that Schlegel, 
Thomas, and Max Weber are of opinion that these are no distinct 
species, but regional varities. 
The skulls, mentioned here as Frisians, are old ‘‘mound” skulls 
from the first centuries of our aera and hence may be looked upon 
as representatives of the Germanic skull which may be indicated as 
skulls of the Homo europaeus, frisius. The above mentioned skulls 
of Zeelandians were obtained from the drowned land of S. Beveland.
