Show 1891.] MR. R. LYDEKKER ON A N E W MOA. 479 Since the present specimens are so much larger than the corresponding bones of Ciconia alba, it seems certain that they cannot be referred to Pelargodes magnus, which is of the approximate dimensions of the hitter. Compared, however, with the leg-bones of the unnamed Stork from Allier, which agrees more nearly in size with the larger Leptoptilus javanicus, and is provisionally referred in the Museum Catalogue to the genus Propelargus, the fossils under consideration agree so well in relative size that there is every probability that they belong to the same species. In the Museum Catalogue I suggested that the Allier Propelargus might prove to be inseparable from P. cayluxensis of the Phosphorites, on which grounds I refrained from assigning to it a separate designation. There is, however, no proof of this specific identity ; many of the Mammals of the Phosphorites being distinct from those of the Allier Miocene-a larger proportion being, indeed, identical with those of the Paris Basin. Under these circumstances I propose provisionally to regard the coracoid under consideration as the type of a new species to be tentatively assigned to the genus Propelargus, with the title of P. (?) edwardsi. Even if this should prove to be identical with Milne-Edwards's Argala arvernensis, m y name will still stand. The specimens here described are not only of interest from their unusually fine state of preservation, but also as proving the existence at a period as early as the Lower Miocene of a Stork of the dimensions of the smaller species of Leptoptilus, and evidently very closely allied to genera still existing. 3. On a new Species of Moa. By R. LYDEKKERJ B.A. [Received August 13, 1891.] (Plate XXXVIII.) The large number of more or less well-defined species of Moas already recorded from the superficial deposits of N e w Zealand1 might have been supposed to have included all the members of that group which existed in those islands during the later geological epochs. Among a collection of Moa-bones recently purchased by the Hon. L. W . Rothschild I have, however, found au associated series of specimens clearly indicating an undescribed species, although one which, in my opinion, should be referred to a genus already established. By the courtesy of their owner I am enabled to bring these specimens under the notice of the Society ; and I am especially glad to do this, since nearly all the known species of the group have been first described in its publications. The specimens in question comprise the right femur and the two tibio-tarsi and tarso-metatarsi. They are all much weathered, and 1 In the ' Cat. Foss. Birds Brit. Mus.' (1891) 18 named species are provisionally recognized, while four imnamed forms may indicate as many additional species. PROC. ZOOL. Soc-1891, No. XXXIII. 33 |
