PEOE. H. G. SEELET ON THE EEPTILE 



ported by the circumstance that the tibia has a strong ligamentous 

 ridge that would correspond to the rough side of the fibula. 

 Moreover T have found a further small portion of the supposed shaft, 

 not absorutety continuous, but showing that the bone retained the 

 same characters for some length further, and did not expand at its 

 distal end. It therefore may be well to state that this specimen 

 (PI. XXVII. fig. 20) is to be regarded as a right fibula imperfect at 

 the proximal end, but, as preserved, 4^ centim. wide. As pre- 

 served, the main piece of bone is over 10 centim. long, and, with the 

 additional fragment and the lost interspace, would indicate a length 

 of about 14 centim. The distal end is imperfect, having decomposed 

 before fossilization. The anterior margin is concave, the posterior 

 margin straight and rugose. The thickness of the proximal end, as 

 preserved, is about a centimetre, while the fractured distal end is 

 7 millim. thick and about 17 millim. wide. As remarked by Eiinzel, 

 the distal fracture is semiovate, but the flattened side is towards the 

 transversely convex head of the bone, while the convex distal outline 

 is towards the transversely concave or external surface of the head. 

 Other fragments of similar character, also presumably fibular, but too 

 imperfect for detailed description, may be referred, one to a larger 

 and one to a smaller Dinosaur. 



Metatarsal Bone. 

 (See Biinzel, pi. iv. figs. 11, 12.) 



The specimen regarded by Biinzel (t. iv. f . 11, 12) as the phalange 

 of a Crocodile is almost too imperfect for accurate determination ; 

 but since it is certainly either the second or third metatarsal of a 

 Dinosaur, probably the former, it requires a slight notice. As pre- 

 served, it is little more than Q\ centim. long and about 3 centim. 

 wide in front. What I take to be the inferior surface is the best 

 preserved ; only a small portion remains of the anterior articular 

 end, which was unusually convex from above downward. The lateral 

 outlines are concave ; and the bone measures only 2 centim. from 

 side to side in the middle, where most constricted. The superior 

 surface was compressed, so as to form an obscure broad rounded 

 ridge on the outer side, with a very slight broad channel below it on 

 the inner side. The depth of the bone in the middle of the shaft is 

 2-1 centim. The under surface is concave in length, flattened from 

 side to side, with a slight twist in the plane, which is directed a little 

 inward as it extends forward. The posterior fractured end is sub- 

 triangular, owing to the flattening of the base. 



Claw-Phalange. 

 (See Biinzel, pi. iv. figs. 4, 5.) 



A claw-phalange (Pi. XXIX. fig. 6), probably pertaining to the 

 second or third digit of the left hind limb, as indicated by Biinzel, 

 is ascribed by that writer to a species of Scelidosaurus, but may 

 be referred to Crataomus lepidophorus. It is 33 millim. long, 25 

 millim. wide behind, and 22 millim. wide in front, is compressed
