is recognized, Ponco pycmM#us Hoppius, erroneously attributed 
to Linneus, and eight ‘dimorphic’ subspecies, according to the 
presence or absence of cheek callosities as follows:

Pongo pygmzus pygmeus .... agrias nomen nudum .. pygmeus. 
Pongo pygmeus wurmbi ..... TT ee ae Cnet eee skalauensis. 
Pongo pygmeus dadappensis . dadappensis .......... genepatensis. 
Pongo pygmeus bicolor ..... MCA Fk le y ciegs oe bicolor. 
It will thus be seen that all of Selenka’s races are received, but 
with only one peculiarity, and that ‘dimorphic,’ (it cannot be con- 
sidered a character), attributed to them. 
As it has not been proven that cheek callosities are ‘dimorphic,’ 
or any evidence whatever produced to sustain his position, the Author 
of the paper being the only one to express this view of the case, and 
all the indications we possess, obtained from the study of skins and 
skulls, seeming to show that these growths are not ‘dimorphic’ but 
purely an individual peculiarity, as they attain any size only on some 
old males, and are not in evidence in the young or half grown indi- 
viduals, and no skull at any age indicates that these abnormities have 
ever existed, therefore it cannot be said that, with only our present 
knowledge to guide us, the Author’s view of this question should be 
accepted. .

*If the Bornean and Sumatran Ourangs are specifically the same, as at 
present seems the fact, then pyGMus is the proper name for these Apes; but if 
they are distinct the Bornean Ourang should be called “wurst,” the Sumatran 
“ABELII.”
