The ribs are long and slender, the first but little expanded distally and 

 united with the prsesternum a little behind its middle. They number 

 eighteen, but as the last is quite long, there may have been another pair of 

 shorter ones not yet exposed in the matrix.

There are four sternal segments preserved, with a fragment of another. 

 They are distinct, and the first is the largest. It is a longitudinal plate, 

 placed on edge, with the anterior border strongly excavated. The inferior 

 margins of the succeeding segments are thickened, but the compressed form 

 remains, the section being triangular. 



The scapula is large for the size of the animal. It has an approximately 

 triangular form, the base being superior. The posterior angle is right, but 

 the anterior regularly rounded. The apex supports the glenoid cavity on 

 a neck which is contracted by a shallow excavation of the anterior margin. 

 The latter is bounded next the glenoid cavity by the short obtuse coracoid, 

 which stands a short distance above the articulation. The spine is long, 

 rather elevated, with a regular convex border curved backward. It rises
