Jaresh-Inyo, a male Grazerite.
The Grazerites are humanoid members of the Federation hailing from the planet Grazer. They require little sleep and a layer of fine, downy fur covers their hide-thick skin. Grazerite facial features include a pronounced, deeply furrowed brow and a bovine snout. Two slightly curving horns, which may reach 10 centimeters in length, crown the Grazerite skull. Current fashion calls for a tight-fitting cloth cowl to cover the horns.
The Grazerites had a position on the Federation Council in the late 24th century held by Jaresh-Inyo until he was elected Federation President. (DS9: "Homefront, "Paradise Lost")
Background Information
