are rounded and elevated above the flattened niaxillaries, bend boldly out from the nasals, approx- 
imating only in the anterior third of the beak, then continuing parallel, become flatter and wider, 
and extend slightly beyond the maxilla?. 
The posterior angles of the maxillae are spatulate, the vomer is hidden by the mesethmoid 
cartilage. Below, the vomer appears as a thin flat plate an inch wide, extending to the anterior 
fourth of the beak. The palatines are broad, with the anterior lateral angles obliquely truncate ; 
they have, on the whole, an abbreviated "dice-box" shape. Their greatest length is 9.5 inches; 
width at the anterior and posterior ends across the two, 10 inches. Their least width in the 
middle, 8 inches. 
The length from the tip of the beak to the median notch of the inferior nares is thirty -eight 
inches ; from the bottom of the notch to the posterior recurved process of the alisphenoid, four 
inches; to anterior basi- occipital suture, five inches — the middle of the otic bulla? being in the 
same transverse line. The anterior ends of the bulla? are an inch from the recurved process of 
the alisphenoid. 
The bullae are very regularly ovoid, and smooth below ; the lateral external edges have two 
deep grooves separating three bulbous prominences. They were so attached by dried membranes 
to the cranium that a fuller examination was impracticable. The width of the inferior surface of 
the maxilla?, in the middle of the beak, is G.5 inches. The height of the narial se2ituin, behind, 
is 1.5 inch. Depth of brain cavity, 8 inches; height of orbit, 4.5 inches. The condyles of the 
lower jaw are large and thick ; the rami are stout in proportion to their length. There is no 
angular process ; the coronoid process is sharp and high ; the dental foramen large, just before 
the condyle. The inferior groove between the occipital condyles is almost evanescent.
