the suprascapular border, but distally becomes nearly straight. The suprascapular 
border is regularly convex; the coracoid, or anterior, border, is short and nearly 
straight, but’ presents near the juncture with the suprascapular border a tubercle 
which causes a convexity in the outline. The acromion is large, and directed out- 
ward or downward. The shape of the anterior and posterior borders is very char- 
acteristic of the species. Among American specimens this peculiar form is found 
well developed in the type of B. césarctica Cope, at Philadelphia, in the Amagansett 
(N. Y.) skeleton in the National Museum (No. 23077), in the Charleston skeleton, 
in the skeleton in the Field Columbian Museum, Chicago; and less well defined in 
the Long Id. (N. Y.) skeleton in the American Museum of Natural History. 
Holder’s figure of the scapula of this skeleton is taken at an angle and does not, 
therefore, show the true shape. (See text figs. 88 to 93; also pl. 45, figs. 2-5.) 
The following are actual measurements of the greatest breadth and height of 
the scapula in various American and European specimens :

A scapula from a partial skeleton found at Beaufort, North Carolina, has, accord- 
ing to Mr. R. L. Garner, a breadth of 51 inches. The Raleigh Museum skeleton, 
which is as large as the Christiania skeleton No. 2, is, unfortunately, without the 
scapulz. Cope recorded in 1868 that there was in the museum of Rutgers College, 
New Brunswick, N. J., a scapula 484 in. broad and 36 in. high. He estimated that 
this indicated an individual 57 feet long, but in view of the dimensions given in 
the foregoing table this appears improbable.’

Gasco gives (47, 40) the following formula for the Taranto skeleton, I, 0? ; II, 
4; III,5; 1V,3; V,3. Professor Rios y Rial also gives a formula for the Guetaria 
skeleton, but it appears to be entirely hypothetical.
