THE VARIETIES OF THE HUMAN SPECIES. 



3t 



Of this singular form I have so far found two variations dis- 

 tinguishable by the norma verticalis: ist, the australejisis, of which 

 I give the type in Fig. 5 ; and 2d, the brachyrhoniboides 

 aegyptiacus, shorter and wider than the preceding. 



N. B. That these forms are often found in infantile crania is a 

 fact worthy of attention. 



4th. Ovoid (ovoides). This form (Fig. 6) is distinguishable only 

 by the norma verticalis. The enlargement of the cranium is at 

 the parietals at about a third of their entire length and posteriorly. 

 The occiput terminates at the large apex of the ^^^, while the 

 second apex is represented by the frontal. The cranium has sym- 

 metrical curves; the arch is not always very convex and may have 

 a transverse curve, slight and easy. 



Fig. 6.— Ovoides. 



The ovoid cannot be confused with the pentagonoid, because it 

 has no sides, nor apparent corners, nor has it the occipital obli- 

 quity which forms the posterior part of the two posterior sides of 

 the pentagonoid. 



The " Sardinian ovoid," which I have described and named 

 sardiniensis, diverges a little from this type; the enlargement of 

 the parietals is situated a little in advance of that in the type 

 described,, and, besides, the ovoidal appearance is also perceived 

 in the norma lateralis.
