I screwed the blue thingers. Anyway the first one is Coire Lagan on the Isle of Skye. The Second mentions a river: "(lg´n) (KEY) , river, c.40 mi (60 km) long, rising in Slieve Croob, SE Northern Ireland. It flows NW, then NE past Lisburn to Belfast Lough at Belfast. The port of Belfast and its shipbuilding yards are located at the mouth of the Lagan; a canal joins the river to Lough Neagh."
