272 THE HISTORY OF CREATION, 
(Huxley’s last three families), from Genuine Apes, or Simiz 
(the first four families), For, as I have already shown in my 
General Morphology, and explained in the last chapter, the 
Semi-apes differ in many and important respects from 
Genuine Apes, and in their individual forms are more 
closely allied to the various other orders of Discoplacentalia. 
Hence the Semi-apes must probably be considered as the 
remnants of the common primary group, out of which the 
other orders of Discoplacentalia, and, it may be, all De- 
ciduata, have developed as two diverging branches. (Gen. 
Morph. ii. pp. 148 and 153.) But man cannot be sepa- 
rated from the order of Genuine Apes, or Simiz, as he is 
in every respect more closely allied to the higher Genuine 
Apes than the latter are to the lower Genuine Apes. 
Genuine Apes (Simiz) are universally divided into two 
perfectly natural groups, namely, the Apes of the New 
World, or American Apes, and the Apes of the Old World, 
which are indigenous to Asia and Africa, and which for- 
merly also existed in Europe. These two classes differ prin- 
cipally in the formation of the nose, and they have been 
named accordingly. American Apes have flat noses, so that 
the nostrils are in front, not below; hence they are called 
Flat Noses (Platyrrhini). On the other hand, the Apes of 
the Old World have a narrow cartilaginous bridge, and the 
nostrils turned downwards, as in man; they are, therefore, 
called Narrow Noses (Catarrhini). Further, the jaw, 
which plays an important part in the classification of 
Mammals, is essentially distinct in these two groups. All 
Catarrhine, or Apes of the Old World, have exactly the 
same jaws as Man, namely, in each jaw four incisors above 
and below, then on each side a canine tooth and five cheek
