lias boon soloclod rrom t.lio collection at Cairo as forming an approximately complete vertebral 
column. Owing, bo\ve\(‘r, to the great variation in size in individuals of the iiresent species it Mas 
impossible to make a very satisfactory set, and it is not even certain that some of the smaller 
vertebric may not bcdtiiig to Paliroinaalodon. Only the discovery of an associated series can make 
it possible to settle didinitidy the structure of the vertebral column and tbe numlier of vertebrre 
composing its difterent regions. The description given above (pp. 27-82) is founded on this series, 
and the ligures also are, for the most part, taken from vertebroe composing it. The numbers of 
the vertebnc bidiind the cervical region are only approximate. 
C. 8303. Third cervical vertebra (text-fig. 10, A). 
C. 9097. Fourth cervical vertidjra. 
C. 8294. Fifth cervical vertebra (text-tig. 10, B). 
C. 9083. Sixth cervical vertebra. 
C 9082. Seventh cervical vertebra (text-fig. 10, E). No vertebrarterial canal. Rib-facets on 
hinder face at ventral outer angle of centrum. 
The dimensions (in centimetres) of these cervicals are given in the following table : —

C. 9089. Anterior thoracic vertebra. Spine higher than in last cervical. 
C. 8270. Anterior thoracic vertebra. At this jioint there is probably a gap in the series. 
C. 7806. Thoracic vertebra (text-fig. 11). Sjduo very high, broad. 
C. 8316. Thoracic vertebra belonging to a smaller individual than the last. 
C. 9215. Thoracic vertebra of a small individual. Neural sjiine shorter than in last. 
C. 9091. Thoracic vertidira (text-fig. 12). Centrum is somewhat narrowed ventrally. Broad, 
flattened, transvei'se process(*s, with oval fiat rib-facets (/./’.) towards the front of their 
outer ends. Neural spine {n.sj).) strongly inclined backwards, upper end slightly bifid.

Behind C. 9091 there seems to be a 
gap in the 
series, in 
which the 
neural 
s[)incs shortened, the 
capitular rib-facets moved higher up, and the zygapoiihyses became cylindroid. This type ol 
vertebra is shown in text-lig. J3,
