also, from the World of Gor a brief description along with where they can be found in the books~
Kur, Kurii (noun): the Torvaldsland word for beast, and a Gorean corruption of the Kurii's word for themselves; they are an alien race locked in combat with the Priest-Kings for control of Gor. Brutal and violent, and capable of space technology, some were marooned upon Gor and suffered to live by the Priest-Kings, usually in the northern regions; they regard humans as cattle for consumption. Huge creatures, standing some eight to nine feet, their arms are seven feet in length, terminating in six-digited, extrajointed pawlike hands. The legs are thick, and short, and the creature can run on all fours similar to a simian, with great rapidity.
---Marauders of Gor, 1:21, 6:92 and 11:169-170
