Section I.: Mounting Lizards, Alligators, etc.—Reptiles of this description should be skinned like mammals, through a longitudinal insertion made in the abdomen. The skin from the top of the head cannot be removed however. In mounting, proceed exactly as in mammals, but as there is no hair to hide defects, all cotton, excelsior, etc., wound on the bones must be very smooth. The attitudes of all this class of animals are apt to be stiff and ungainly even in life; but by putting a bend or two into the tail, turning the head, or slightly curving the body, too much rigidness may be avoided.
Section II.: Mounting Turtles.—To remove the skin from a turtle, cut away a square portion of the under shell, using a small saw for this purpose. Then remove the softer portion through this hole, and draw out the legs and head as in mammals; but the top of the head cannot be skinned over. In mounting proceed as nearly as possible as in mammals, only the legs may be filled with clay or plaster in small specimens. Care should be taken not to fill the skin too full; but let the wrinkles show, as seen in life, and imitated as nearly as possible.
The shell of the soft-shelled turtle, like the leather-back, is quite difficult to keep in good condition—is apt to become distorted in drying. The only method which has occurred to me is to cover the body, and exposed under portions, with layers of plaster, which will keep the shell in position until it is dry, when it may be removed.
Section III.: Mounting Fishes.—Fishes are quite difficult to skin, especially those with scales. In flat fishes I remove a portion of one side, skinning the other; then, in mounting, lay the animal on its side. Mounting in this case means filling the fish to its natural life-size with cotton, tow, or other available material. Plaster or clay will also answer. The fins may be pinned out flat against pasteboard, or put in place with fine wire.
In skinning larger fishes, or those which have no scales, or scaled fishes which have cylindrical shaped bodies, open from beneath by cutting nearly the whole length of the body. The skin from some fishes comes off easily, while in others it is more difficult to remove. In mounting large fishes use a hard core to the body, made of either wire or wood. The fins should be wired from the inside; care should be taken that the skin lies smoothly over the surface beneath, as it shows considerably in drying, and all imperfections around it.
In preserving the skins of all reptiles and fishes the dermal will be found excellent, especially in removing the oil from the skins, etc. Cover well with the preservative, and nothing more will be necessary. Skins of this class of animals may be kept for future mounting by simply coating with the preservative, and kept turned wrong side out without filling. When they are to be mounted throw them into water, in which a small quantity of dermal has been dissolved. When they are soft turn and mount as in fresh skins.
