The bones of the thoracic limb of forty-one Japanese serows (♂22, ♀19) from Ina and Kiso in Nagano Prefecture were anatomically investigated, and compared with those of the goat, sheep and ox. The nomenclature was based on Nomina Anatomica Veterinaria Japonica (1981). 1. The bones of the thoracic limb of the Japanese serow consisted of the scapula, humerus, radius, ulna, carpus, metacarpus, digits, sesamoids and two nodular vestigial phalanges in a dew claw. The various parts of the bones were observed. 2. The bones of the thoracic limb of the Japanese serow had general features of the bones of ruminants and generally resembled those of the goat and sheep, and they could be distinguished from those of the ox with size of each bone. 3. The scapula of the Japanese serow was distinguished from those of the goat and sheep in the following points:spine, tuber spinae, acromion, neck, glenoid cavity, glenoid notch, supraglenoid tubercle, coracoid process, free border and nutrient foramen. 4. The humerus of the Japanese serow was distinguished from those of the goat and sheep in the following points:greater tubercle, teres minor tuberosity, deltoid tuberosity, teres major tuberosity, lateral epicondyloid crest, olecranon fossa, coronoid fossa, radial fossa and nutrient foramen. 5. The radius and ulna of the Japanese serow were distinguished from those of the goat and sheep in the following points: proximal interosseous space, body of the radius, nutrient foramen of the radius, olecranon, coronoid process, body of the ulna, and fusion of the radius and ulna. 6. The carpal bones of the Japanese serow resembled of those of the goat, sheep and ox. But the accessory carpal bone did not resemble that of the ox, and resembled those of the goat and sheep. 7. The fifth metacarpal bone in the metacarpus of the Japanese serow was found in one third of the all Japanese serows. 8. The digits of the Japanese serow were long and thin, which were similar to those of the goat and sheep, while those of the ox were short and thick.
