Apteryx

Definition and stakes

Portrait of Edward Hamilton Aitken Edward Hamilton Aitken,  Concerning Animals and Other Matters

“ Its nostrils, unlike those of every other bird, are at the tip of its beak, which is swollen and sensitive; and Dr. Buller says that as it wanders about in the night it makes a continual sniffing and softly taps the walls of its cage with the point of its bill. But the apteryx is one of those odd geniuses which come into the world too soon, and perish ineffectual. Its kindred are all extinct, and so will it be ere long.
When we come to the beasts we find the right conditions at last for the growth of the nose. Take the horse for an example of the average beast without idiosyncrasy.

“ But the Apteryx differs most essentially in the structure of the cranium and mandibles, from the extinct types to which Professor Owen has given the names of Dinornis, Palapteryx, Aptornis, &c.
With regard to the construction of the feet it may be further remarked, that the length of the inner and outer toes is nearly equal, as in the Cassowary; but the middle toe, which in the Cassowary is one-third longer than the other digits, in the Moa scarcely exceeds in length by one-fifth, the inner and outer toes. The ungueal segments are very large, being equal to one-third the length of the toes.

“ Apteryx, which since Owen has generally been stated to be devoid of such an organ, likewise possesses a pecten; its base is, however, trumpet-shaped, covers almost the whole of the optic disk, and extends nearly to the lens in the shape of a thick, densely pigmented cone, without any plications, resembling in these respects the pecten of many Lacertilia (see G.L. Johnson, Phil. Trans., 1901, p. 54) . In the retina the cones prevail in numbers over the rods as in the mammals, and their tips contain, as in other Sauropsida, coloured drops of oil, mostly red or yellow. ”
