Spider leg-muscles have been redescribed and the absence of extensor muscles at two joints confirmed. The possibility that the flexors at these joints act in antagonism to the blood-pressure is discussed. The coxal muscles are inserted on to sclerites in the rim of the trochanter and autotomy occurs at this joint. At autotomy the sclerites are detached from the trochanter and support the articular membrane, which restricts bleeding.
