130 THE MYOLOGY OF THE RAVEN. 



pair of powerful pronators in the forearm of this bird. 

 It arises by a tendon rather above the internal condyle 

 of the humerus ; the fibres, forming a thick fusiform 

 muscle, pass obliquely across the interosseous space to 

 become inserted on the ulnar side of the shaft of the 

 radius, just beyond the junction of the proximal and 

 middle thirds. This muscle is somewhat compressed

This synonymy is immediately followed by a concise description 

 (in the same work) of the proaators, they agreeing substantially 

 with my 2jronator hrevis and longus (Nos. 77 and 78) respectively. 

 Then comes a description of Prof. Gadow's m. entepicondylo-ulnaris, 

 a muscle, according to his description, that takes origin from the 

 internal condyle of the humerus and is insei'ted into the ulna. Thus 

 far I have failed to discover the particular muscle to which he 

 refers. From the synonymy given above it will be observed that 

 Tiedemann and others designated it as the Flexor hrevis idnce. Prof. 

 Gadow's descriptions are in the main very brief, and the figures of 

 his plates (for the most part copied from Alix, De Man, and 

 Watson) are by no means satisfactory, so that it is possible, or more 

 than likely, that one runs the chance of mistaking the muscle he 

 refers to in some cases. I have omitted the synonymy in several 

 instances, as will be noted below.
