InMgotlieles there is a slight difference in that there is hardlyany trace of the wristward branch of the tendon. Steatornishas an expansor secundariorum, apparently absent amongthe other genera. The muscle is attached to the teres by itslong tendon. The insertion of the deltoid is extensive, andit receives a tendon from the scapula. In many Caprimul-gidae the biceps is split for some distance before its insertion,,the bifidity even invading the muscle itself and not being.
