32023, 2. A nearly similar right tarso-mctatarsus ; from Ruamoa.

 its outer as compared with its inner ridge.

32023, 3. A nearly similar left tarso-metatarsus ; from the same 

 locality. Walter Mantell Collection. 



e. The Femur. 

 Some of the more slemhr of the undermentioned specimens pro- 

 bably belonrj to species a, bat it is difficult to separate them 

 decisiveii/ from typical specimens. 



32001 a. The right femur ; from Ruamoa. This specimen, which 

 (i-Vr/.) is figui-ed in woodcut 57, B (p. 223), has a length of 

 0,317 (12-5 inches), and a distal width of 0,164 (6-5 

 inches). It exhibits all the characteristic features of the 

 genus, and is thus in very marked contrast with the femur 

 of Dinomis maximus, represented in fig. 57, A (p. 223). 

 The length of the neck, the lowness of the great trochanter, 

 the structure of the linea aspera, and the large size and 

 ill-defined contour of the popliteal depression being all 

 well displayed. Walter Mantell Collection. 



32001 b. A nearly similar but somewhat more slender right femur ; 

 from the same locality. Walter Mantell Collection. 



A. 180. A right femur ; from Otago. This specimen is somewhat 

 intermediate in contour between the two preceding 

 examples. i\-o history. 



A. 180 a. A somewliat smaller right femur ; from Otago. The 

 proximal extremity is somewhat affected by caries. 



A'o history. 



A. 180 b. A shorter and stouter right femur ; from Otago. 



No history. 

 A. 180 C. A still shorter right femur ; from Otago. No history. 



A. 180 d. A nearly similar but rather more slender specimen ; from 

 Otago. Xo history. 



32001 c. A right femur of a more slender form than either of the 

 preceding specimens ; ft-om Kuamoa. This specimen, 

 which probably belongs to species a, has a length of 0,325
