A large, long-legged, light-boned argali with the most spectacular horns of all the world's sheep. The summer coat is a light, speckled brown, with the face, chest, underparts, rump patch and legs white. In winter, the upper parts are a somewhat darker brown and there is a full white neck ruff extending to the brisket. The winter hair is much longer, making the animal appear larger and heavier than it is. The long, slender horns are homonymous, forming 1-1/4 to 1-1/2 open spirals, and triangular in cross section with a sharp orbital-nuchal edge. The longest sheep horn ever recorded (75 inches, or 190.5 cm) (Rowland Ward, 1895), is from a Marco Polo; however the largest circumference for this race is only 17 inches (43 cm), with 14 to 15-1/2 inches (36-39 cm) usual. Horns and skull together will weigh only about 25 pounds (11-12 kg), the horns' slimness making them seem longer than they actually are.
