0,241 (U-5 inches), and a width at the middle of the shaft of 

 0,004 (2"G inches), so that its i)roportions are very similar 

 to those of the corresponding hone of the type skeleton. 

 The third trochlea shows the characteristic shape very 

 clearly ; hut the external border of the outer proximal 

 articular surface is less squared than is usually the case.

47444, 9. A slightly shorter and stouter right tarso-metatarsus ;

32018 a. The right tarso-metatarsus ; from lluamoa. This speci- 

 men resembles Xo. 47444, 8, but the shaft is somewhat 

 less flattened. Walter Mantell Collection.

32018 c. A still smaller right tarso-metatarsus ; from lluamoa. 



The length is 0,223 (S-8 inches), and the width at the 

 middle of the shaft 0,00o (2-55 inches )

32022 a. A considerably smaller right tarso-metatarsus ; from 

 Euamoa. Walter Mantell Collection. 



32022 b. A similar right tarso-metatarsus ; from the same locality.

32023 a. A smaller right tarso-metatarsus ; from the same locality.

32023 b. A still smaller right tarso-n^etatarsus ; from the same 

 locality. Length 0,108 (7'8 inches).

32022 C. The right tarso-metatarsus ; from Ruamoa. This specimen 

 has nearly the same length as Xo. 32022 a, but in the 

 more flattened and wider shaft it approximates to the 

 next form. Walter Mantell Collection. 



32019 a. The left tarso-metatarsus ; locality unknown. This bone 



has the same approximate length as the largest speci- 

 mens of the right side ; the lateral expansion of the outer 

 border of the third trochlea is less sudden than usual.
