The insidious larvae, however, are not so easily observed, burrowing as they do among the feathers, or in the interior of a skin ; whilst the minute eggs are commonly altogether overlooked. But the "bugs" are not long at work without leaving their unmistakable traces. Shreds of feathers float off when a specimen is handled, or fly out on flipping the skin with the fingers, and in bad cases even whole bundles of plumes come away at a touch. Sometimes, leaving the plumage intact, bugs eat away the horny covering of the bill and feet, making a peculiarly unhappy and irreparable mutilation. I suppose this piece of work is done by a particular insect, but if so I do not know what one. It would appear that when the bugs efi'ect lodgment in any one skin, they usually finish it before attacking another, unless they are in great force. We may consequently, by prompt removal of an infested specimen, save further depredations;.
