caudal haemal arch is attached below the interspace between the third and fourth caudals. 

 The epicotyloid tubercle is strongly developed : the ilia articulate with the first sacral vertebra 

 exclusively, but the ischia abut against the long transverse processes of the first caudal : 

 beyond this vertebra the ischia develope on each side two tuberosities, one at the visual place, 

 the other and stronger one near the lower end of the symphysis. 



2277. The left scapula. 



It is remarkable for the number and strength of the intermuscular cristae : of these, that 

 which is commonly called the ' spine ' is the largest, its breadth being equal to that of the 

 infraspinal fossa : this fossa is bounded by a second ridge, formed anteriorly by the outwardly 

 bent lower cost a, but being distinct from the costa at its posterior third. The two principal 

 masses of the ' subscapularis ' muscle were divided by a longitudinal crest, like the spine, 

 rising from the inner surface of the scapula. Both the acromion and coracoid are well 

 developed. 



2278. The left clavicle. 



2279. The left humerus. 



It is perforated above the inner condyle : this is a tuberosity which appears to be supported 

 by four converging columnar ridges or processes. The deltoid and snpinator ridges are well 

 marked. 



2280. The left ulna. 



The shaft is much compressed. 



2281. The left radius. 



2282. The left femur. 



It shows the almost equal development of the three trochanters. The medullary artery 

 enters on the inner side of the shaft, just below the small trochanter. 



2283. The left tibia and fibula with the interarticular ossicle of the knee-joint. 



2284. The left tarsus and metatarsus. 



There is an accessory ossicle wedged between the calcaneum, astragalus, naviculare, and 

 entocuneiforme .
