Abstract
In the year 1877 I published a preliminary description of certain Dinosaurian remains obtained from the Lameta group of the Jabalpur district of India, to which I applied the name of Titanosaurus indicus . The Lameta beds, it may be observed, have been usually referred to the Middle Cretaceous (Upper Greensand), but later observations indicate that they may be of somewhat newer age. The remains on which the genus was founded are preserved in the Indian Museum, Calcutta, and comprise an imperfect femur, and a considerable number of late caudal vertebræ, together with one imperfect vertebral centrum from an earlier part of the series. In a later memoir I gave figures of some of the more important of these specimens, and came to the conclusion that the vertebræ indicated two species, for the second of which I proposed the name of T. Blanfordi , adding the proviso that this form might eventually turn out to be generically distinct from T. indicus . Both these types of late caudal vertebra3 are characterized by their strongly proccelous centra, to the anterior half of which the anchylosed neural arch is confined; and in the one perfect specimen of T. indic~es the arch carries two well-marked processes, one of which is directed anteriorly and the other posteriorly. The preaxial process is bifurcated anteriorly, and bears a pair of prezygapophysial facets ; while the hinder one, which (judging from the caudal vertebrm of the Sperm-Whale and of certain other Dinosaurs)I think includes the representative of the neural spine
