Discussion 



There appear to be distinct differences in the rate of growth with size (or age) in certain 

 parts of the body in Hintonia candens. Although isometry is indicated for most of the charac- 

 ters given in Table 44, allometry is also indicated in that the smaller sizes tend to have higher 

 values for thousandths of standard lengths (with no overlap), the values decreasing with 

 increasing size offish; this is true for the lengths of the head and upper jaw, and the prepec- 

 toral, prepelvic, and predorsal lengths. Conversely, the depth of the caudal peduncle appears to 

 be relatively greater in smaller than in larger specimens. 



An unusual, and not readily explained, curvature of the vertebral column, determined by 

 X-ray, occurred in about 29%> of the specimens. This curvature (Fig. 207) appears not to be a 

 result of distortion during preservation, for several specimens having a distinct bend in the 

 body in the area of the curvature shown in Fig. 207 were manually straightened and pinned to 

 a paraflfm block and X-rayed; the curvature of the vertebral column persisted. Similar vari- 

 ously pronounced curvatures of the vertebral column were found in the remaining specimens, 

 although some of the bodies were somewhat bent. As the figure of the holotype, drawn by Bolin 

 (Fig. 205), shows a distinct bend in the body, the vertebrae column is probably also curved.
