In references to the pelvis, I fail to find mention of the epipubic 

 cartilage becoming ossified. Such is distinctly the condition in 

 the skeleton of the female, and the following sketch shows its 

 form and relative position. 



This bone is not ankylosed with the pubic, and may therefore 

 be easily lost during the process of maceration. The additional 

 figure in the foregoing table of measurements, is inclusive of this 

 epipubic bone. 



The apex of the entoplastral spine reaches a point situated 

 220 mm. behind the edge of the gular prominence, it has a width 

 of 12 mm., and is quite free from the plastron for 45 mm. at its 

 distal extremity. 



The accompanying Plate (xxii.) is reproduced from a photograph 

 of the skeleton of the female, from which one side has been re- 

 moved to show the internal structure. It will be seen that the 

 horny sheaths covering the jaw have been retained and that the 

 hyoids are suspended in their natural position. The extent and 

 attachment of the epibubic bone, above referred to, may also be 

 traced.
