The insects to which it hears the nearest affinity are the Hippoboscidæ or "spider flies," that infest birds and horses, but, unlike them, it is unable to fly.
Its strangest peculiarity, and that which gave rise to the belief that it is headless, is its faculty when at rest of throwing back its head and pressing it close between its shoulders till the under side becomes uppermost, not a vestige of head being discernible where we would naturally look for it, and the whole seeming but a casual inequality on its back.
On closer examination this apparent tubercle is found to have a leathery attachment like a flexible neck, and by a sudden jerk the little creature is enabled to project it forward into its normal position, when it is discovered to be furnished with a mouth, antennæ, and four eyes, two on each side.
The organisation of such an insect is a marvellous adaptation of physical form to special circumstances. As the nycteribia has to make its way through fur and hairs, its feet are furnished with prehensile hooks that almost convert them into hands; and being obliged to conform to the sudden flights of its patron, and accommodate itself to inverted positions, all attitudes are rendered alike to it by the arrangement of its limbs, which enables it, after every possible gyration, to find itself always on its feet.

BIRDS.
Of the Birds of the island, upwards of three hundred and twenty species have been indicated, for which we are indebted to the persevering labours of Dr. Templeton, Dr. Kelaart, and Mr. Layard; but many yet remain to be identified. In fact, to the eye of a stranger, their prodigious numbers, and especially the myriads of waterfowl which, notwithstanding the presence of the crocodiles, people the lakes and marshes in the eastern provinces, form one of the marvels of Ceylon.
In the glory of their plumage, the birds of the interior are surpassed by those of South America and Northern India; and the melody of their song will bear no comparison with that of the warblers of Europe, but the want of brilliancy is compensated by their singular grace of form, and the absence of prolonged and modulated harmony by the rich and melodious tones of their clear and musical calls. In the elevations of the Kandyan country there are a few, such as the robin of Neuera-ellia[1] and the long-tailed thrush[2], whose song rivals that of their European namesakes; but, far beyond the attraction of their notes, the traveller rejoices in the flute-like voices of the Oriole, the Dayal-bird[3], and some others equally charming; when, at the first dawn of day, they wake the forest with their clear reveille.
