21706**. A nearlj' similar left tarso-metatarsus ; from Te Raii- 

 gatapu. Mantell Collection. 



**Anomalopteryx didina (Owen '). 

 Syn. Dinornis didinus, Owen -. 



Founded upon the associated skull, cervical vertebrae, and lower 

 portions of the limbs. 



Distinguished from the type of A. didiformis by the longer tarso- 

 mctatarsus ; and from the skeleton referred to that species by the 

 proportionately much larger skull and the greater size of the hallux. 

 In the type the length of the tarso-metatarsus is 0,188 (7"4 inches), 

 and that of the tibio-tarsus 0,492 (15-5 inches). 



It is quite probable that this form may be cither not distinct 

 from A. dromaoides or only a local race of that species. It is like- 

 wise probable that some of the specifically undetermined specimens 

 mentioned above (pp. 267-269) should be referred to this species. 

 The form of the temporal fossa of the skull is not exhibited. 



Ilah. Typically the South Island. 



A. 16. Part of a .skeleton, with remains of the integuments and 

 {Fig.) feathers ; found in a fissure-cave, disclosed by a landslip, 

 near Lake Wakatipu, Queenstown, Otago, Soiith Island. 

 The type. The specimen includes the head, neck, and the 

 limbs, exclusive of the femora. The sclerotic ring of the 

 eye and the rings of the trachea remain in their natural 

 position. The specimen is described by Owen in the 

 ' Trans. Zool. Soc' vol. xi. pp. 257-261, with figures of 

 the head, neck, and one of the feet in pis. lix.-lxi. The 

 length of the tarso-metatarsus is 0,188 (7'4 inches, not 

 6-8 inches as given in Owen's description). The tibio- 

 tarsus has a length of 0,492 (15-5 inches), and a distal 

 width of 0,061 (2-4 inches). The large size of the ter- 

 minal claw of the hallux is very noticeable. The skull 

 has a narrow rostrum and mandibular symphysis, but the 

 form of the temporal fossa is concealed by the integuments. 

 The trachea is seen to be composed of very slender rings.
