width, 59mm, ; mid. width, 32mm.; and distal width, 76mm. 

 I have not seen a tibia which I can refer to this species. Mr. 

 Lydekker gives the average length at 342mm., and distal 

 width 55mm. There are three femoi-a in our collection, all 

 from Te Ante. The largest is : Length, 221mm. ; prox. 

 width, 82mm. ; mid. width, 38mm. ; distal width, 84mm. The 

 smallest is: Length, 201mm.; prox. width, 75mm.; mid. 

 width, 34mm. ; distal width, 72mm. There is also a small 

 pelvis from Te Ante which has the characteristics of Pachy- 

 ornis, and which, therefore, I refer to this species (Plate 

 XLVIIL, fig. D). The middle of the ilium is situated at the 

 posterior margin of the acetabulum ; the pre-acetabular ridge, 

 formed by the ilia, is straight axially ; the posterior portion 

 of the ilium is very broad and flat ; the ventral surfaces of the 

 centi'a of the sacral vertebrge are strongly curved transversely, 

 l)ut are not so narrow as in P. elephantopus. The following 

 are its dimensions: Length of ilium, 305mm. ; length of the 

 pre-acetabular portion of the ilium, 127mm., and its depth, 

 76mm. ; width at the antitrochanters, 159mm.

Professor C. Stewart has been kind enough to send me a 

 cast of the type femur of this species, which is preserved in the 

 museum of the Eoyal College of Surgeons. This specimen, 

 which is slightly abraded at the proximal end, has the follow- 

 ing dimensions : Length, 235mm. ; proximal width, 84mm. ; 

 mid. width, 35mm. ; distal width, 84mm. There is in the 

 Canterbury Museum collectioTi a femur from Te Aute which 

 has the same size and shape, but in which the popliteal depres- 

 sion is deeper. These femora are not those of a true Anomal- 

 ornis, but might belong to a species of Cela or Meionornis. 

 It is just possible that the tibia and metatarsus, here in- 

 cluded provisionally as A. gracilis, may belong to D. dro- 

 mcBoides, but they have the characters of Anomalornis and not 

 those of Meionornis. There is in the Auckland Museum a 

 very imperfect pelvis, which may also belong to D. dro- 

 iiiaoides ; its width at the antitrochanters is 184mm. 



Palapteryx geranoides, Owen, Trans. Zool. Soc, iii., p. 361 

 (1848), pi. 54 (E.B., pi. 45), figs. 1-7. Anovialopterijx(>) 

 geranoides, Lydekker, I.e., p. 290. 

 This species is founded on a skull, and is therefore not 



comparable with the others, which are founded on leg-bones. 



Mr. Lydekker proposes to take either the metatarsus or the 



tibia described by Owen under the same name — Pachyornis
