corrib, lough, a lake of western ireland, in the counties galway and mayo. it lies n.w. and s.e., and is 27 m. long, including a long projecting arm at the north-west. the extreme breadth is 7 m., but the outline is extremely irregular, and the lough narrows near the centre to a few hundred yards. lough corrib is very shallow, hardly exceeding 30 ft. in depth at any point, and it is covered with islands, of which there are some 300. it lies 29 ft. above sea-level, and drains by the short river corrib to galway bay. the large lough mask lies to its north and is connected with it by a partly subterranean channel. the scenery is pleasant, but the shores are low, except at the north-west, where the wild foothills of joyce's country rise. corridor (fr. _corridor_, from ital. _corridore_, med. lat. _corridorium_, a "running-place," from _currere_, to run), a main passage in a large building, on which various apartments open. in public offices, prisons, workhouses, hospitals, &c., the corridors are usually of severe simplicity; but in mansions and palaces large corridors (galleries) are often adorned with works of art, whence comes the term "picture gallery" applied to many collections. the term "corridor carriage" is applied to the modern style of railway carriage in which a narrow passage connects the separate compartments, the object being to combine a certain degree of privacy for the traveller with access from one compartment to another whilst the train is in motion. corrie (gaelic _coire_, cauldron; hence whirlpool, or circular hollow), a term used in the highlands of scotland for a steep-sided, rounded hollow in a mountain-side, from the lower part of which a stream usually issues as the outlet of a small lake ponded by glacial debris. corrie-lakes are common in all glaciated mountain regions.
