D'Azara gives 30 inches as the length of the young bird described by him ; that of the l'rinco de Vied was half an inch more, and the adult male of the Museum of the Netherlands, from which Tenuninek's figure was taken, measures, according to him, 32 inches. The nestlings are covered with down, and with the iris of a very lively yellow. They are very soon able to run.
Temminck, after observing that the eariama at first view seems to offer some resemblance to the Secretary-Bird of Africa (G,ypogeranus with that of the Common Bittern (Botaurus stcllaris), of the Agatni (Paophia orepitans), and the Grallatorcs generally. There is a skeleton of fl female in the museum of the Zoological Society of London pre sented by the Earl of Derby, in whose possession the bird died. An account of the anatomy of this bird by Mr. Martin was published in the Proceedings of the Zoological Society.' In this paper Mr. Mnrtin observes that "in its general aspect the skeleton of the carinum is very remarkable. The comparative shortness of the neck, the com pactness of the chest, and stoutness of the ribs, together with the abbreviated condition of the wings, appear as if out of harmony with the length of the limbs, especially of the tibia and tarsus, while the toes concluding this length of limb are short, the hinder one being situated high and not touching the ground.
" Though the eariama in its osseous structure exhibits but little resemblance to the birds of the Raptorial order, it approaches that order very remarkably in the structure of the eye, which is surrounded by a firm consolidated osseous ring. This ring departs materially in its formation from what obtains among the Grallatores generally, where it is imbricated and slight, and indeed scarcely merits the name of osseous." For the anatomy of the bird we refer the reader to Mr. Martin's paper, but we may observe that, according to Mr. Martin, " in the whole of the visceral arrangement a close affinity may be observed to the Gres tribe." In the Stanley Crane (Anthropoids,' paradimrus, Bechst.) the intestines are similarly disposed in folds or loops, and the two cteca, given off 6 inches from the anus, nre 4 inches long. In the Stanley Crane however the muscular coat of the gizzard is thicker than in the eariamn, being in some parts an inch across, while in the latter bird it is about one-fourth of an inch; hence is there in this point an index of a loss vegetable regimen. In the Stanley Crane the total length of the intestines is 5 feet 3 inches. In the eariama it is 3 feet 54 inches.
