metacarpal commences ridge-like, immediately distad of the conical 
process on the postaxial side of the head. This is the most obvious 
of the several means of distinguishing this bone from P. carbo. Size 
considerably less than in P. gregorii. Locality, Wurdumulankula. 
Distal half of a left carpometacarpal (Plate IX., figs. 5 A, B). The 
junction of the third with the second metacarpal is much longer 
than in P. carbo, The distal articular surface is very similar to 
that of P. carbo, and in size it approaches very nearly to that 
of P. gregorii, to which, indeed, it might be referred, rather than to 
the present species. Locality. Lower Cooper. 
Proximal end and part of the shaft of a left bone similar to 
the first, Locality, Malkuni. (Plate IX., figs. 7 A, B.) 
Nearly complete bone of the right side, but minus the third 
metacarpal and with the distal articulation imperfect. This is a con- 
siderably smaller bone than the preceding, but on all other accounts 
cannot be separated from them. Locality, Lower Cooper. 
Femur. — Plate VIII., figs. 5 A. B. — A right femur, entire but 
for the loss of a small part of the fibular facet of the outer 
condyle. Compared with the femurs of the larger cormorants, 
P. carbo and P. gregorii, the dimensions of this bone vindicate 
the belief that it belongs to a distinct species. In length, it is 
51.5 mm., in the least breadth of its shaft, 5.3 mm. ; in P. gregorii 
the length is 54.5 mm., the breadth, 6.5 ; in P. carbo the length is 
58 mm., the breadth, 6.5 mm. The salient structural features of 
the bone are a thin, sharp, somewhat tortuous linea aspera (B a), 
and from the trochanter an extensor cruris ridge of the same 
character, a continuation of the ridge proximad in an oblique 
line on the shaft (B b), immediately proximad of the inner con- 
dyle, and the pit on the head for the inter articular ligament, as 
deep as in P. carbo — that is, much deeper than in P. gregorii. 
Locality, Malkuni. 
A left femur, entire except for superficial injury to the head 
and condyles. The identification of this bone depends on size 
and proportions, which are very much the same as in the preceding 
case, but it is rather stouter in proportion to its length. Its ridges 
are not quite so pronounced, and the interarticular pit is shallower. 
Locality, Lower Cooper. 
Tibia. — Proximal half of a right tibia (Plate VIII., figs. 6 A, 
B, C), corresponding in size to the femur from Malkuni. Its inner 
crest (A a) is much deeper than in P. carbo or P. gregorii. The 
outer crest is much less expanded. As in P. gregorii, the articular 
surface viewed perpendicularly (C)" is comparatively short, the 
crests being much less extended forwards. Locality, Malkuni. 
Proximal third of a right tibia (fig. E.). Locality, Malkuni. 
Tarsometatarstts. — Shaft of a left metatarse (Plate VIII., 
fig. 7). The proportions of this bone are the only means of determining
