Bulletin of the British Ornithologists' Club. cribed as Elornis (?) show characters suggesting that they originate from a flamingo similar to recent species, which may be assigned to the Phoenicop- teridae. Introduction One of the two flamingos described by Lydekker (1891) from the Upper Eocene of Britain, Agnopterus hantoniensis, has been placed in a separate family, the Agnopteridae (Howard 1955). The type humerus of the other, Elornis anglicus, is now considered referable to a species of a different suborder (Harrison & Walker, in prep.), leaving in the material ascribed to the true flamingos, Phoenicopteridae, at this period only two bone fragments assigned by Lydekker to Elornis (?) spp. Both are from Hordle (=Hordwell), Hamp- shire, and were said to be portions of right tibiotarsi. The first, presented by Sir Richard Owen in 1884 (B. M. reg. no. A 2) is from the proximal part of the shaft of a right tibiotarsus, showing part of one end of the fibular crest. The other, from the Hastings Collection, purchased in 1855 (B. M. reg. nos. 30289 = A 2670) is, in fact, a portion of the shaft of a tarsometatarsus, apparently from a similar bird. Description The first specimen is 95 mm long and about x mm at its thickest point, tapering a little before the fibular crest begins. The shallow proximal end of the tendinal groove is visible on the anterior surface, almost as far as the fibular crest. There is a conspicuous ridge almost along the centre of the posterior surface but a little nearer the internal side; the internal half of the surface curving away to join the more flattened anterior surface at a rather rounded edge, while the external half slopes away to join the anterior surface abruptly, producing a blade-like ridge along the external edge and giving the bone a characteristic transverse section (fig. 2, B). The second specimen is mm long and X mm thick. It is sufficiently uniform to prevent B 0. Please note that these images are extra
