42685. The imperfect distal extremity of the right tibio-tarsus ; from 

 the cavern-deposits of the ^\'ellington Valley. Xoticed by 

 Davies in the ' Gaol. Alag.' decad. 3, vol. i. p. :^65, as 

 D. novce-lioUand'uT. The ectocondyle is wanting. In the 

 great width of the distal extremity of the shaft, and also 

 in the large size of the internal cavity, this specimen 

 agrees with the smaller and more imperfect example figured 

 by Etheridge, Joe. dt. 



A. 57 a. Cast of the imperfect distal extremity of a somewhat larger 

 right tibio-tarsus. The ectocondyle is wanting. The 

 proportions are similar to those of the preceding specimen. 



A. 57 b. Cast of the proximal half of the left tarso-metatarsus. 



Subfamily C a s u a r 1 1 n >e. 



The femur has no pneumatic foramen on the posterior aspect of 

 its proximal extremity, and its shaft is not compressed. The distal 

 extremity of the tibio-tarsus may be either broad, with a deep semi- 

 lunar pit on the lateral surface of the ectocondyle (C. mneu and C. 

 unicqjpendmdatus), or narrow and without such pit (C. j^icticullis) ; 

 its extensor groove is deep, but most so in the latter type. The 

 tarso-metatarsus is stout and much shorter than the tibio-tarsus. 

 The second phalangeal of the third digit of the pes is thick and 

 much constricted laterallv.

Casuarius, sp. 



[Allied to C. picticoUis\ of New Guinea.] 



The distal extremity of the tibio-tarsus is narrow, without a 

 semilunar pit on the lateral surface of the ectocondyle, and with 

 a very deep extensor groove.
