its medial and anterior sides are slightly overhanging. The medial border 
rounds off into the posterior one. The greatest breadth of the medial side is 
ii cm. The posterior border converges slightly with the anterior border to- 
wards the lateral side; its length is io cm. The distance from the anterior 
medial corner of the distal end to the lateral end of the processus posterior 
is nearly 16 cm. 
A broad high ridge runs down from the tuberositas tibiae in the direction 
of the anterior medial corner of the distal end, but disappears in the lower 
half of the bone. The lateral anterior edge of the distal end is broadly rounded 
below. Higher up the edge becomes a fairly sharp ridge, which disappears 
above the middle of the bone. There is a broad low boss on the lateral side 
of the bone, below the notch in the lateral border of the proximal surface. 
Its highest point lies about 8-5 cm. below the notch. The surface of the bone 
being generally crushed, no further particulars can be given. The thickness 
of the bone in the middle is 7 cm. and its breadth at this place 5-5 cm. Both 
dimensions were originally somewhat larger. The thickness of the distal end 
is slightly more than 9*5 cm. At the middle fracture the bone shows a thick 
wall of substantia compacta but no substantia spongiosa. The central cavity 
is fairly large. 
There are three fragments of the same specimen which could not be identi- 
fied with certainty. One of these is probably a piece of the shaft of a femur. 
Another piece might be identifiable if better material were present for com- 
parison. The third piece is an end of a large bone. The surface at the end has 
a length of 17-5 cm. and a breadth of 11 cm. At one end the sides of this 
surface meet at an acute angle; at the other end its border is broadly rounded. 
The shaft becomes rapidly narrower and at a distance of 10 cm. from the end 
its breadth is 8-5 cm. Its thickness at this point may be about 5 cm. The 
only bones it could belong to are the ischia and the fibulae. For the distal 
end of the ischium it is far too large, but for the distal end of the fibula it 
also seems too large. Its shape is exactly what one would expect of the distal 
end of the fibula. * 
Two other bones were found in the same locality, which belong to a much 
larger animal. One is a fragment of a tibia and the other of a coracoid. The 
tibial fragment was found loose on the same spot as the remains described 
above. It has probably broken away from higher strata. The coracoid was 
found loose on a very much higher level and was probably originally in the 
same conglomeratic bank as the tibial fragment. 
The fragment of the tibia is the lateral portion of the head of the right 
bone. It has a length of 22 cm. corresponding with about 13 cm. in the tibia 
of Eucnemesauvus . In comparison with the head of the Eucnemesauvus tibia 
the head under discussion may have had a total length of 33 cm. 
The coracoid consists only of the foramen supracoracoideum with some 
bone substance around it. It is apparently a right coracoid. The foramen 
passes upwards and inwards. Its outer opening is oval shaped, having a 
width of 3-5 cm. and a height of 2-8 cm. The inner surface below and behind 
the foramen is concave, the outer surface convex. The thickness of the bone 
immediately behind the foramen is 3 cm. It becomes thinner towards the 
scapular border. Immediately in front of the foramen the bone has a thickness 
of 6-5 cm. Both these bones indicate Theropodous Dinosaurs of tremendous 
size. 
Discussion. 
The described remains of the smaller animal show Plateosaurid characters, 
and especially is the tibia so typically Plateosaurid that I do not hesitate in
