There are five sacral vertebrae anchylosed together, which have flattened haemal surfaces. The left ischium, which has been described by the writer, op. cit. p. 50, is represented in fig. 39; its total length is 0,870 (36-5 inches). Apart from the evidence of the vertebrae, the fact that the ischium agrees in relative size with the type ilium, and comes from the same horizon, leaves little doubt as to its specific identity. The resem- blance of these bones to the ischia of Camptosaurus and Hypsilopliodon renders it probable that the pubis was of the elongated type of these genera. It. 811 a.
