named by the writeP in 1879 on the evidence of four 
Mr. Theobald in the Siwaliks of the Punjab, which 
form the subject of the present | notice. 
Phalangeals . — Of the first Specimen three views are given in plate XIV, figs. 2, 
2a, 2b. This bone is the first' phalangeal of the outer (fourth) digit of the right 
foot of a tridactyle struthioid; and is in fair preservation, but has lost a small 
portion of the inner border of \the proximal extremity (fig. 2b). In figure 6 of the 
same plate there is represented the corresponding bone of the opposite foot of a 
slightly smaller struthioid. This specimen has been considerably rolled ; and its 
distal extremity, as well as tlije anterior aspect of the ])roximal extremity, are 
consequently imperfect. In general contour this bone is very similar to the last ; 
but has the inner extremity ofl the proximal surface [a) somewhat more produced. 
It is somewhat doubtful whetheif these differences in size and form should be regarded 
as of individual or specific valjie ; but it seems advisable in the absence of other 
evidence to regard them provisionally in the former light. These bones are very 
near indeed to the correspondi[ng bone of Promceus novce-hollandice ; being mainly 
distinguished by the slighter development of the pit on the inner asjject of the distal 
extremity, and their considerably larger size. They do not come so close to the 
corres^Donding bone of any othdr struthioid. 
In figure 5 of the same pla^e there is represented the second phalangeal of the 
outer digit of the left foot of a jtridactyle struthioid, agreeing in relative size with 
the larger first phalangeal (fi^. 2). This bone is only distinguished from the 
corresponding phalangeal of thej living emeu by its superior size and the somewhat 
greater expansion laterally and Interiorly of the outer articular trochlea [a). Both 
the recent and fossil bones are cparacterized by the presence of a pit on the outer 
side only of the distal extreniitV. There is every j^robability that the fossil belongs 
to the same species as the first phalangeal represented in fig. 2. 
In figs, 4, 4a, 4b of the I same plate there are given three views of a larger 
second phalangeal of the same digit and foot, which corresponds so exactly in form 
with the smaller specimen that it evidently belonged to the same kind of bird.
