MUSCLES OF THE HIND LIMB 103 Flexor secundus (adductor) digiti IV. is a muscle whichappears to be generally absent ( Giconia), and is not,according to Gabow, mentioned by authors. It is presentin Rhea and Bucorvus. The last-named muscle may be the equivalent of thefirst of the two short flexors which arise from the deep longflexor tendons. Of these there are two.
