After having studied a bipedal and a quadrupedal Orthopodous Dinosaur I thought it desirable to turn my attention to a bipedal representative of the Saurischian order.
Though Streptospondylus is by no means an exclusively British Dinosaur, since the type-specimen is preserved in the Jardin des Plantes in Paris, and was described, under the names Streptospondylus and Megalosaurus by Cuvier and Gaudry, still, the only other specimen known, and by far the best, is in Mr. J. Parker's private collection at Oxford. It is to Mr. Parker's kindness that I owe the possibility of studying and drawing what may be called one of the most complete Theropods ever found, while in the Paris Collection Streptospondylus is only represented by several vertebrae, a fragment of the femur, and the distal part of the tibia with the corresponding astragalus. Mr. Parker's specimen includes the skull, most of the cervical, dorsal, sacral, and some of the caudal vertebræ, the scapulo-coracoid, parts of both humeri, the ilium, ischium, parts of the pubis, both femora, tibiæ, and fibulæ, some tarsal and all the metatarsal bones, and several phalanges.
