122 and are somewhat longer than the 3rd. The 6th is slightly wider & longer than the 5th. The 7th is longer & broader than the 6th & the 8th is the longest of the series. From this back they decrease gradually in length & increase very gradually in width. These observations are of the chevron's in situ - whether or not the actual measured length would correspond with this or not I can't tell until they are cleaned. The 8th is however, the highest or longest as the series stand in position. The anterior chevron's base of the series are directed back- ward & permit a considerable antero-posterior movement. The 2nd + 15th chevron's are about equal in height as they stand in position, but The last chevron is exceedingly minute but it ossified - 1 The last two caudals very small all both very small Teeth 19-19 Posterior teeth on both jaws 22-22 exceedingly minute to rent show severe the gums, with 'the alveoli' are distinct juts in which the teeth may be found.
