Material examined.
Simalia amethistina (Schneider, 1801) (QM J51148 View Materials ); Simalia boeleni (Brongersma, 1953) (SMF PH 110).
Description (Figs 162-167).
Trunk vertebrae. Centrum much shorter than wide; cotyle and condyle orbicular or moderately (ventrally) depressed; neural arch vaulted or moderately vaulted; posterior median notch of the neural arch deep; neural spine of medium height; prezygapophyseal accessory processes vestigial or very short; hypapophyses disappearing after V 70 ( Simalia boeleni ) or between V 80 and V 90 ( Simalia amethistina ); haemal keel in more posterior vertebrae moderately developed and moderately broad; paracotylar foramina absent.
Trunk / caudal transition. A hypapophysis, that appears in the last trunk vertebra, diminishes gradually in size in more posterior vertebrae; in the last cloacal vertebra(e) or first caudal vertebra it can be considered a haemal keel, with flattened (slightly grooved in Simalia amethistina and Simalia boeleni ) posterior end. Haemapophyses (unpaired unilateral in S. amethistina ) first appear on the second caudal vertebra (Fig. 167 View Figure 167 ).
Number of vertebrae. Simalia amethistina (QM J51148): 416 (355+4+57, including a final fusion); Simalia boeleni (SMF PH 110): 378 (305+5+68).
Data from literature: Simalia amethistina : 323 trunk vertebrae plus 106 cloacal and caudal vertebrae ( Nopcsa 1923); Simalia amethistina : 318-322 ± 5 trunk and cloacal vertebrae plus 118-119 ± 1 caudal vertebrae ( Alexander and Gans 1966); Simalia amethistina : 322 trunk vertebrae plus 10 cloacal vertebrae (apparently erroneous) plus 92 caudal vertebrae ( Rochebrune 1881); Simalia boeleni : 360-363 vertebrae in total ( Parmley and Reed 2003).
