are also laterally compressed. The bronchie are almost entirely 
membranous, having only seven or eight weak and narrow rudimen- 
tary rings externally. 
The gizzard and ceesophagus 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 scapule, 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 scapule 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 vertebre. 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 vertebre 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
