older designations. Owen then reassigned B. magnus to the genus Chondrosteosaurus as Chondrosteosaurus magnus in 1876, considering it closely related to the type species Chondrosteosaurus gigas from the Wealden. Hulke described additional sauropod material from the Wealden in 1879, and reevaluated the designations used by Owen and Seeley. Hulke identified BMNH R28632 as the type of O. hulkei, rendering Bothriospondylus magnus and Chondrosteosaurus magnus as junior objective synonyms. As well, Hulke noted that the comment of Owen that the name Ornithopsis was misleading was false, as the vertebrae were lightly-constructed regardless of their relationships. Hulke also referred the genus Eucamerotus, named earlier by him in 1870, and the genus Chondrosteusaurus to Ornithopsis as junior synonyms, with other fossils found in the Wealden beds showing that they all shared the unique internal structure of Ornithopsis. Though William Blows identified in 1995 that most of the Wealden sauropod material has been designated as dubious or intermediate, the type vertebra of Ornithopsis shows unique features in its lateral compression and a ventral ridge, and represents a diagnostic titanosauriform. Additional species Hulke described pelvis material, BMNH R97, from the Wealden in 1882, found associated with a few vertebrae, as the new species Ornithopsis eucamerotus. He retained Eucamerotus and Chondrosteosaurus as synonyms of Ornithopsis, but suggested that O. hulkei should only contain the original vertebra BMNH R2239. The designation by Hulke of BMNH R2239 as type conflicted with his earlier assertion that BMNH R28632 was the type, so Lydekker corrected this in 1888 by formally designated BMNH R28632 as the only type with the consultation of Seeley. Hulke described more material as Ornithopsis in 1887, for some vertebrae, ribs, a pelvis, and fragments collected in the Eyesbury Jurassic deposits of Northamptonshire by Alfred Nicholson Leeds. The vertebrae and pelvis showed many similarities with the specimens of Ornithopsis from the Wealden Group, but the much larger size of the Eyesbury specimens, their robusticity, and their older age were considered sufficient to describe as a new species, which Hulke named Ornithopsis leedsii after the discoverer Alfred Leeds. Hulke placed the genus within the sauropod family Atlantosauridae, suggesting a close relationship with Cetiosaurus oxoniensis. The specimens named as Ornithopsis leedsii are stored as specimens BMNH R1985-1988, having been collected in May of 1892, and possibly being the first sauropod collected by Leeds and his brothers. Unlike the other specimens, O. leedsii came from the lower Callovian deposits of
