[ σκελετόν , & dry body: see skele- ton.] Those hard or skeletal parts, collectively flamm at i on of the sclerotic and choroid coats considered, which result from the o ification of tendons, ligaments, and similar sclerous tis- sues, as sesamoid bones developed in tendons, o ified tendons, as those of a turkey's leg, the marsupial bones of marsupials, the ring of bonelets in the eyeball, etc. Such o ifications are generally considered apart from the bones of the main endoskeleton. To those named may be added the bone of the heart and of the penis of various animals. Tendons of birds are specially prone to o ify and form scleroskeletal parts.

In birds the sclerotals are usually from twelve to twenty in eye number. The sclerotic coat is very dense, almost gristly in some cases; and it is reinforced by a circlet of bones, the scle rotals. These are packed alongside each other all around the circumference of one part of the sclerotic, like a set of splints. The bony plates lie between the outer and middle coats, anterior to the greatest girth of the eyeball, extending from the rim of the disk nearly or quite to the edge of the cornea. Coues, Key to N.
