known by the extent to which the inner edge of the base overlaps 
the edge of the sternum when it is in place, but the transverse 
extent of the overlapping is apparently shorter than in living 
Cormorants, as short, indeed, as in Plotus. Locality, Lower Cooper. 
Humerus. — Plate VII., fig. 2 A, B. — Proximal two-fifths of a 
left humerus, fairly well preserved, its worst injury being the loss of 
the proximal border of the pneumatic foramen. The bone is, on the 
whole, very similar to that of P. carbo, but the following differences 
are observable : The capitum is shorter, and is more distinctly 
marked out by greater depth in the incisura capitis on the one 
side (fig. B a.), and in the space ventrad of the tuberculum 
externum (fig. B b.) on the other. The whole of the bone is 
narrower in proportion to its length. Locality, Malkuni. 
Distal four-fifths of a right humerus, in good preservation, 
of the same length as in P. carbo, but with a slenderer shaft. The 
probrachialis scar (Plate VII., fig. 3 B a.), which in P. carbo is 
interrupted in the middle, is in this continuous or nearly so ; the 
proximal end of the ulnar condyle (fig. B b.) is more deeply incised 
on its ventral side, and the proximal edge of the incision is sharp ; 
the entepicondyle (c.) is shorter and more tumid, the ridges on 
the postaxial surface (A a.) are sharper, the grooves between 
them broader and deeper. Locality, Kalamurina. 
Distal two-thirds of a right humerus, fairly well preserved, 
In this the probrachialis scar is continuous. In other respects, it 
is similar to the preceding. Locality, Lower Cooper. 
Distal half of a right humerus, scar continuous, postaxial 
surface of joint abraded, otherwise as before. Locality as 
preceding. 
Shaft of a right humerus. Locality, Malkuni. 
Distal fourth of a left humerus, well preserved. Locality as last. 
Distal fourth of a left humerus, also well preserved. Locality, 
Lower Cooper. 
Carpometacarpal. — Entire length of a carpometacarpal 
of the right side, somewhat longer (by 2 mm.) and slenderer than 
that of P. carbo. The rotular groove of the proximal articulation 
is narrower and the cavity at the anterior side of the conical process 
on its ventral aspect is broader and deeper. There are numerous 
points of difference in the sculpture of the two bones, but these 
cannot be explained without dwelling to an unjustifiable extent 
on minute detail ; some of them are apparent in the drawing 
(Plate VII., fig. 4). Locality, Lower Cooper. 
Fragment from the preaxial side of the carpometacarpal 
joint, consisting of the carpal process for the pollex metacarpal, 
and part of the rotular groove. This conveys no further information. 
Locality, Malkuni. 
Femur. — A left femur, nearly entire ; shorter by 3 mm. than 
a P. carbo femur, and with narrower ends, it is yet of the same
