Distinr/uished from the iirccediny forms by the infedion of the distal 

 extremity of the tihio-tarsus. 



Anomalopteryx (?) geranoides (? Owen). 



Syn. (?) Palapteryx geranoides, Owen '. 

 Dinornis geranoides, Owen -. 



A small aberrant species, in which the tibio-tarsus has an average 

 length of 0,342 (13-5 inches), and a distal width of 0,055 (2-15 

 inches), the distal width thus being about one sixth of the length. 

 The tibio-tarsus is longer and relatively stouter than the corre- 

 sponding bone of A. curta, and is characterized by the inflection of 

 its distal extremity, after the manner of Pachi/ornis. Tertebrse 

 probably referable to this species are mentioned under the head of 

 A. curta. 



The tarso-metatarsus accords in relative stoutness and shortness 

 with the tibio-tarsus, its average length being 0,152 (6 inches), and 

 the width at the middle of the shaft 0,034 (1-35 inch). In this 

 respect it presents a marked contrast to the corresponding bones of 

 A. didiformis and A. ixirva. The femur referable to this form is 

 mentioned on page 273, and is likewise characterized by its extreme 

 shortness and stoutness, as compared with the corresponding bone 

 of A. parvci. 



The under-mentioned cranium, which must be taken as the type 

 of Palapteryx geranoides, agrees better iu relative size with the 

 above-mentioned limb-bones than with those of A. curta. 



The name Pedapteryx r/eranoides was said by Owen to indicate 

 " an unpublished species defined from certain leg- bones sent home 

 by the Rev. Mr, Cotton since the communication of my former 

 memoir."' These bones were, however, never described or figured, 

 and cannot now be identified. The imperfect crania mentioned 

 below, which were provisionally referred to that species, must 

 therefore be taken as the actual types of that form. The tarso- 

 metatarsus subsequently figured by Owen as Dinornis geranoides 

 may belong to the same form as the skull ; but, if not, the under- 

 mentioned specimens of the tibio-tarsus may be taken as the act ual 

 tj'pes of A'. (?) geranoides, which will then rank as a new species. 

 This type of skull resembles that of A. didiformis, and differs from 

 that of A. parva and A. oweni in having a flattened surface sepa-
