1. On some Remains of large Dinosaiieian Reptiles from the Storm- 

 BERG Mountains, South Africa. By Professor Huxley, F.E.S., 



y.p.G.s. 



In a box of fossils sent to Sir E. I. Murchison, Bart., by Mr, Alfred 

 Brown of Aliwal I^orth, South Africa, and snbmitted to me for 

 examination and determination, I found certain •fragmentary large 

 reptilian bones, to which a very considerable interest attaches. 



The most im23ortant of these are two femora, a right and a 

 left. The articular ends of both of these bones are wanting ; and 

 the shaft of the left is far less complete than that of the right, to 

 which the following remarks more particularly apply. 



It is broken into four pieces ; but these, when carefully fitted 

 together, have a total length of 25*5 inches; and it may be safely 

 assumed that the length of the entire femur exceeded 30 inches, as 

 its distal extremity is only beginning to widen for the condyles. At 

 20'5 inches from the proximal end, the transverse diameter of the 

 shaft is 5-1 inches, the antero-posterior diameter 4*2 inches. The 

 contour of the transverse section at this point is a transversely 

 elongated oval, the posterior face being so much more flattened than 

 the anterior as to make it almost semilunar.
