The Mexican Axolotl (Siredon mexicanum) is the neotenic larval form of Ambystoma mexicanum. The axolotl is a convenient laboratory animal, suitable for many types of investigation. This paper supplements a previous article where the natural history, variations, and races of axolotls and their handling and breeding in the laboratory have been described. The skeleton, the nervous and vascular systems, the alimentary tract and its appendages (including the spleen), and the respiratory and genitourinary systems have been described. Some histologic features of the epithelium, the connective tissue, the blood, and the nervous tissue have been briefly described and the skin, the teeth, the gills, the lungs, and the eye have been considered. Underdevelopment of the female sexual apparatus, some hereditary malformations, and abnormalities connected with the ability for regeneration and malnutrition have been described. Pigment spots, melanotic tumors, adenocarcinoma, and tumorlike structures (after implantation of parts of axolotl embryo) have been considered.
