1891.] MR. R. LYDEKKER ON A NEW MOA. 479 



Since the present specimens are so much larger than the corre- 

 sponding bones of Ciconia alba, it seems certain that they cannot be 

 referred to Pelargodes inagnus, which is of the approximate dimen- 

 sions of the latter. 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 provisionallj^ referred in the 

 Museum Catalogue to the genus Propelargus, the fossils under con- 

 sideration 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 re- 

 frained 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-Edvvards's Argala arvernensis, my 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. 



[Eeceived August 13, 1891.] 

 (Plate XXXVIII.) 



The large number of more or less well-defined species of Moas 

 already recorded from the superficial deposits of New Zealand ' 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. Kothschild I have, however, jbund an associated series of 

 specimens clearly indicating an undescribed species, although one 

 which, in my opinion, should be referred to a genus already estab- 

 lished. 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 



^ In the ' Cat. Foss. Birds Brit. Mus.' (1891) 18 named species of Dinorni- 

 thidm are provisionally recognized, while four unnamed forms may indicate as 

 many additional species.
