a. The Tarso-metatarsus. 



A. 168. The left tarso-metatarsus ; probably from the South Island. 



{Fig.) This specimen (fig. 66, B) is the type. Its length is 0,228 

 (9-9 inches), the width of the narrowest portion of the 

 shaft 0,084 (3-3 inches) and the width across the trochlea 

 0,164 (6-5 inches). The trochlese are somewhat im- 

 perfect, but exhibit the contour characteristic of the genus. 

 The figure of the specimen is reversed. 



Bij exchange, 1890. 



47444 i. A smaller right tarso-metatarsus, in an imperfect condi- 

 tion ; from Otago. This specimen, which may probably 

 be referred to a male bird, has the same contour as the 

 preceding. The length is 0,205 (8-1 inches), and the 

 width at the narrowest part of the shaft 0,074 (2-9 inches).

b. The Femur. 



32001 k. An associated right and left femur probably referable to 

 this species ; from Ruamoa, three miles south of Oamaru 

 Point, South Island. These specimens are larger than 

 any of the femora referred to P. elephantopus, but present 

 the same generic characters. The length is 0,365 (14-4 

 inches), and the distal width 0,155 (6-1 inches) ; they are, 

 therefore, relatively less expanded than typical examples 

 of the femur of P. elepliantopus.

c. The Skull. 



32303. An imperfect calvarium, provisionally referred to this species ; 

 from the South Island. This specimen, while agreeing in 

 size and generic characters with the cranium of P. ele- 

 phantopus, differs (among other features) by the flattening 

 of the frontal region, the much greater intrusion of the 

 temporal fossae on to the same, the much less prominent 

 basioccipital tubercles, and the longer cavity for the head 

 of the quadrate. Walter Mantell Collection. 



A. 201. Cast of an imperfect skull specifically identical with the 

 preceding specimen ; history of original unknown. The 

 mandible is nearly entire ; but in the cranium the ex- 

 tremity of the premaxillae and the pterygoids and pala- 

 tines are wanting. This specimen agrees in all respects
