r*UU aad locantia f tl>ee higher-orgaai^ Batraehia. The caudal vertebra are rvpre- 

 Mated by a angle, elongated, cylindrical style, having aii anchylosed neural eanal. In the 

 seven vertebra?, between the atlas and the sacrum, two prczygapophyses looking upward*. 

 two poatsygapophysrs looking; downward*, and a hort tpioous process, arc developed from 

 ach Moral arch. 

 Tht boon of the cranium arc numbered according to Table I. of SYNONYMS.

591. The scapular arch and sternum of the same Bull-frog (liana boatu). 



The supraacapula is in great part ossified : the scapula divides at it* humeral end into an 

 aoromial and coracoid proccM ; the latter articulate* with the true coracoid bone, the acromiou 

 with the expanded extremity of the clavicle : the glenoid cavity i* formed by both proOHBM 

 of the scapula, and by the coracoid. An epistemal bone, supporting a broad cartilage, i* 

 articulated to the menial union of the clavicle*, from which a bony bar i* continued backward* 

 between the expanded and partially conjoined end* of the coracoid*. The sternum i* articu- 

 lated to the posterior part of the same extremitie* of the coracoid*.

592. The humeri, antibrachial bones, portions of the carpal bones, and some pha- 



langes, from the same Bull-frog (liana bwnt*}. 



The proximal end of the humenu if an epiphyn* ; the distal end presents a hemispherical 

 ball between a small external ridge and a large internal condyloid process. Thr antibrachial 

 bones have coalesced, but an anterior and posterior indentation at the ditlal half indicates the 

 radius and ulna ; their distal articular extremities are represented by a single epiphysis. The 

 ulnar portion of the bone developes a short and broad olrcranon. 



In the carpal series are preserved the Urge scapho-lunar bone, the cuneiform, the magnum 

 and the unciform bones. 



593. The bones of the hinder extremities of the same Bull-frog (liana loan*). 



Both the proximal and the distal extremities of the femur are in the condition of epiphyacs. 

 The tibia and fibula are ronnslr : a longitudinal impression on the front and back part of the 

 expanded distal end indicates their division, but a single epiphysis, partially ancliylosrd, form* 

 the proxiaMl axtreautj, and a similar one the distal extremity, of the connate bones ; they air 

 perforated near their middle, from before backwards, by a vascular canal. 



The asriagahai and laUaaram are much elongated ; the former is slightly bent, the latter 

 straight ; they have coalesced at their proximal and also at their distal extremities with each 

 other, and with the scaphoid and cuboid bones. Two euaciforas bone* remain detached, and 



immediately support the three inner toe*.
