form symmetrical pairs, gradually becoming atrophied towards the 

 hinder members of the series, and their distal margin is in some 

 cases distinctly crimped. At the twenty-seventh caudal vertebra, 

 where nothing but the delicate elongated centra can be seen, the tail 

 is a little distorted and the remainder is only imperfectly preserved ; 

 but there cannot have been less than 25 centra in this attenuated 

 terminal portion. The caudal region is thus about three times as 

 long as the abdominal region. 



As already mentioned, the crushed remains of the pectoral arch 

 are conspicuous immediately behind the head. The clavicles {cl.) 

 are elongate-ovate in shape, and marked with a linear ornament 

 which radiates from a boss on the outer lateral border of each. 

 They distinctly meet in the middle line in front of the inter- 

 clavicle (i.cl.), which tapers forwards, and seems to be fractured 

 by crushing upon the vertebral column at its hinder border. The 

 latter bone also shows feeble traces of a radiating ornament, but 

 does not bear any longitudinal ridge. On either side of the clavi- 

 cular apparatus, but partly obscured on the left, the internal element 

 (sc), provisionally termed scapula by Huxley, is well preserved, 

 vp-ith the excavated triangular end forwards and the tapering pointed 

 extremity directed backwards. The small, almost reniform bone (x.) 

 touching the latter on the right, overlapping it on the left, may be 

 either a coracoid or the crushed remains of the humerus. The 

 radius (r.) and ulna (?«.) are well displayed on both sides, those on 

 the right in juxtaposition, those on the left crossing each other. 

 The ulna is slightly the larger of the two bones, and there is some 

 appearance of a small olecranon process. The carpus is represented 

 by a blank space, and must thus have remained unossified. The 

 digits are imperfectly preserved, a little crowded on the left, spread 

 out on the right, and it is doubtful whether there are more than four. 

 The metacarpals and all the phalanges except the unguals are a little 

 expanded at each end, while the terminal elements just mentioned 

 are relatively small, slender, and pointed. The first digit preserved 

 on the right side is probably No. ii, and exhibits three phalanges ; 

 the next digit, also complete on the left side, has four phalanges ; 

 No. IV on the right side has again only three phalanges ; No. v is 

 not satisfactorily displayed. 



The fragmentary remains of the pelvis are too obscure for 

 description, but the hind-limbs are well preserved. They are 

 slightly larger than the fore-limbs and clearly exhibit five digits, 

 each terminating in a relatively small and pointed ungual phalange. 

 The femur (fe.) is robust and slightly expanded at each end, much 

 longer than the tibia and fibula, indeed as long as the crus with 

 the tarsus indicated by the vacant space. The tibia (t.) is also 

 stouter than the fibula (Ji.), and its proximal end is much more 

 expanded than its distal end. There is no trace of ossification in 

 the tarsus, but the five metatarsals and their appended digits are 

 so well ossified that the bones may almost be described as terminated 

 with complete condyles. The first digit (i) is relatively small and 

 is crushed upon the second in both feet, but on the right side it
