year. Observations on vertebrae revealed formation of growth checks with
in a short period and gradual decrease in growth rate with age. The length
at formation of first growth check was 226.43 mm. Average back calculated
lengths at formation of successive annual grovvth checks were 224.35,
357.01. 456.77. 553.59. 629.56. 692.05 and 770.90 mm. The Von Bertalanffy
