are also laterally compressed. The bronchise are almost entirely 

 membranous, having only seven or eight weak and narrow rudimen- 

 tary rings externally. 



The gizzard and oesophagus were filled with a species of zoophyte 

 apparently allied to the common sea anemone. The tongue is long 

 and taper, channeled in the middle and horny ; from the epiglottis to 

 its tip it measures five and a half inches. 



The sternum of Aramus is long in proportion to its breadth, mea- 

 suring three and a half inches in length, and at its broadest part, 

 which is near its posterior extremity, one inch in breadth ; its nar- 

 rowest point is at the junction of the posterior ribs, where it is eight- 

 tenths of an inch in breadth, from which point it gradually increases in 

 breadth posteriorly and anteriorly. The posterior margin is entire, 

 without any fissure or foramen, but has a slight undulation in the 

 centre opposite to the point of the keel. The keel is eight- tenths in 

 depth at its widest point, which is about one-third of its length from 

 the anterior extremity ; its inferior edge is much rounded and the 

 anterior much scolloped. 



The OS furcatum, coracoids and scapulars are strong and massive ; 

 the former arched anteriorly, each branch flattened laterally at its 

 junction with the coracoids, and in the opposite direction at its junc- 

 tion with the sternum, so as to have the appearance of being twisted 

 on its axis ; the point at which the branches unite is destitute of any 

 process. 



The coracoids are one inch and seven-tenths in length, and jointly 

 occupy the whole breadth of the sternum, being much expanded at 

 their junction with it; their interior edges are furnished with a thin 

 process beginning at their junction with the scapulae, where it is 

 slightly deflected and continued for about two-thirds of their length, 

 gradually narrowing to that point where it is eventually lost. 



The scapulae are two and a half inches in length, and of uniform 

 breadth to within a short distance of their extremities, where they 

 become pointed, the upper edge becoming deflexed. 



The pelvis is two inches and seven-tenths in length from its ante- 

 rior extremity to the junction of the caudal vertebrae. The upper sur- 

 face on viewing it laterally presents a waved outline, being depressed 

 near its centre, and somewhat raised between that point and its an- 

 terior extremity by means of the anterior branch of the ilium being 

 much expanded. The breadth of the pelvis at its junction with the 

 dorsal vertebrae is one inch ; immediately posterior to the articulation 

 of the femur, which is its widest point, the breadth is one inch and 

 a half; between these points the iliac bones are slightly narrowed 

 laterally, so as to present a nearly uniform curve between them. 

 The ischium is placed nearly perpendicularly, the edge of the ilium 

 projecting over it and forming a prominent ridge along the edge of 

 the plane of the upper surface of the pelvis ; the ischiadic foramen is 

 of moderate size and oval, its greatest diameter being four-tenths of 

 an inch, and its smallest little more than two- tenths ; the obturator 

 foramen is small, or about half the size of the ischiadic one. The 

 OS pubis is rather broad, not prolonged far backwards behind the
