This feature is also very marked in our specimens. 



The most interesting feature displayed by these skulls, 

 however, is the peculiar deformity of the calvarium, which 

 may be described as follows : — A well-marked furrow 

 about 3| cm. in width is seen to rise from the pariefco- 

 squamosal suture on one side, pass upwards over the 

 bregma parallel to and usually behind the coronal suture, 

 and to lose itself at the opposite parieto-squamosal suture. 

 The bregma, as a rule, lies at the bottom of this furrow, 

 and so is dej^ressed ; but, in some cases (e.g., No. 4), it 

 lies behind the furrow, and in others (e.g., No. 3) it lies 

 in front. 



In No. 3, the furrow is shallower, and much broader, 

 than in the other skulls. This peculiar furrow is shown 

 in each of the eight skulls which I examined. It is 

 especially marked in Nos. 1, 2, and 3. A peculiar de- 

 formity of the frontal bone is shown in No. 3. This 

 consists of a keel-shaped elevation, continuous with the 

 Sagittal suture, which runs down the frontal bone, till it 

 is lost just above the ophryon. On either side of this keel 

 there is a well-marked groove. Apparently this is a suture 

 which has been absorbed late in life. 



In two skulls the obelion is depressed. Nos. 1, 3, and 

 4 show a peculiar flattening at the Lambda, so that, in 

 3 and 4, the occipital bone rides over the two parietals. 



The parietal eminences are not very prominent in any 

 of the skulls except in No. 4, where they are well marked. 



The temporal ridges are very prominent in Nos. 1, 3, 

 and 4, but are faintly marked in the remainder of the 

 crania. 



The glabella is not very prominent in any skull, but s 

 more fully developed in Nos. 1, 2, and 3. 



The orbits are rectangular in form. The nasal bones 

 are well-formed, but have been broken in nearly all the 

 skulls.
