configuration of the palate, precoracoid, pelvis, intestinal convolutions, copulatory organ, &c. Loss of the keel is co-ordinated with the power of using the forelimbs for locomotion; although a " Ratite " character, it is not sufficient to turn a Notornis, Cnemiornis or Stringops, not even a Phororhacos into a member of the Ratitae.
The most novel feature, and one the importance of which most ornithologists of the present day are fully prepared to admit, is the separation of the class A y es into two great divisions, which from one of the most obvious distinctions they present were called by its author Carinatae' and Ratitae, 2 according as the sternum possesses a keel (crista in the phraseology of many anatomists) or not.

Its leaves are five or six in number, are about a foot in length and an inch in breadth, and have a blunt keel and flat edges.
The keel has been lost, and is being lost, at various epochs and by various groups of birds.
Although loss of flight (correlated with more or less reduction of the wings and the sternal keel, and often compensated by stronger hind limbs) has occurred, and is still taking place in various groups of birds, it is quite impossible that a new Ratite can still come into existence, because the necessary primitive substratum, whence arose the true Ratitae, is no longer available.
In conformity with these reductions the breastbone of the moas is devoid of any coracoidal facets; there is no trace of a keel, and the number of sternal ribs is reduced to three or even two pairs.
Society, 18 74, p. 594) to be "lost," whereas the clavicles, which in most birds unite to form that bone, are present, though they do not meet, while in like manner the bird has been declared (op. cit., 1867, p. 624, note) to furnish among the Carinatae " the only apparent exception to the presence of a keel" to the sternum.

Two days after this they sighted land to the right hand, and came to a cape, where they found the keel of a ship - perhaps a relic of some earlier, possibly Scandinavian explorer - and which they called therefore Kialames (Keelness; Cape Breton, or some adjacent point?); the long bleak sandy shores of this coast they called the Wonderstrands (on the east coast of Cape Breton Island?).

It is absent in the Ratitae, which from this feature have received their name, but considerable traces of a cartilaginous keel occur in the embryo of the ostrich, showing undeniably that the absence of a keel in the recent bird is not a primitive, fundamental feature.
The separation of the Ratitae from the other birds, and their seemingly fundamental differences, notably the absence of the keel and of the power of flight, induced certain authors to go so far as to derive the Ratitae from the Dinosaurian reptiles, whilst Archaeopteryx (q.v.) and the Carinatae were supposed to have sprung from some Pterosaurian or similar reptilian stock.
Often it reaches the keel of the sternum, with subsequent syndesmosis or even synostosis, e.g.

40), in which there are five petals: - one superior (posterior), st, placed next to the axis, usually larger than the rest, called the vexillum or standard; two lateral, a, the alae or wings; two inferior (anterior), partially or completely covered by the alae, and often united slightly by their lower margins, so as to form a single keel-like piece, car, called carin g, or keel, which embraces the essential organs.
But it was now made to appear that the struthious birds in this respect resembled, not only the duck, but a great many other groups - waders, birds-of-prey, pigeons, passerines and perhaps all birds not gallinaceous - so that, according to Cuvier's view, the five points of ossification observed in the Gallinae, instead of exhibiting the normal process, exhibited one quite exceptional, and that in all other birds, so far as he had been enabled to investigate the matter, ossification of the sternum began at two points only, situated near the anterior upper margin of the side of the sternum, and gradually crept towards the keel, into which it presently extended; and, though he allowed the appearance of detached portions of calcareous matter at the base of the still cartilaginous keel in ducks at a certain age, he seemed to consider this an individual peculiarity.
Some of the usual characters employed for systematic purposes, for the making of convenient keys, are the following: The number of rows of scales across the body and in a longitudinal direction; shape and structure of scales, whether smooth or with a longitudinal keel; arrangement of the shields on the head; shape of the contracted pupil.

This is a very disappointing performance, since the author observes that, notwithstanding his new classification of birds is based on a study of the form of the sternal apparatus, yet, because that lies wholly within the body, he is compelled to have recourse to such outward characters as are afforded by the 1 From carin g, a keel.
3 Some unkind fate has hitherto hindered 2 Thus he cites the cases of Machetes pugnax and Scolopax rusticola among the " Limicoles," and Larus cataractes among the " Larides," as differing from their nearest allies by the possession of only one " notch " on either side of the keel.
The sternum has no keel, and ossifies from lateral and paired centres only; the axes of the scapula and cora.coid have the same general direction; certain of the cranial bones have characters very unlike those possessed by the next order - the vomer, for example, being broad posteriorly and generally intervening between the basisphenoidal rostrum and the palatals and pterygoids; the barbs of the feathers are disconnected; there is no syrinx or inferior larynx; and the diaphragm is better developed than in other birds.'
They also decrease the specific gravity, so that the grain is more readily carried by the wind, especially when, as in Briza, the glume has a large surface compared with the size of the grain, or when, as in H olcus, empty glumes also take part; in Canary grass (Phalaris) the large empty glumes bear a membranous wing on the keel.

In the following year .another set of hints - of a kind so different that probably no one then living would have thought it possible that they should ever be brought in correlation with those of Nitzsch - are contained in a memoir on Fishes contributed to the tenth volume of the Annales du Museum d'histoire naturelle of Paris by Etienne Geoffroy St-Hilaire in 1807.1 Here we have it stated as a general truth (p. too) that young birds have the ' sternum formed of five separate pieces - one in the middle, being its keel, and two " annexes " on each side to which the ribs are .articulated - all, however, finally uniting to form the single " breast-bone."
