noun plural scim·i·tar o·ryx·es, (especially collectively) scim·i·tar o·ryx.

a large antelope, Oryx dammah, once widespread across North Africa, noted especially for its thin, backward-curving, symmetrical horns, which can reach a length of nearly 4 feet (1.2 meters) on both the males and females: hunted nearly to extinction for its horns, it is now believed to exist only in special reserves and was thus classified as extinct in the wild in 2000.
Also called Sa·har·a o·ryx [suh-har-uh awr-iks, suh-hair-uh, suh-hahr-uh] /səˈhær ə ˈɔr ɪks, səˈhɛər ə, səˈhɑr ə/.
