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 burner us ; the fibres, forming a thick fusiform 

 muscle, pass obliquely across the interosseous space to 

 become inserted on the tilnar 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 pronators, they agreeing substantially 



with my pronator brevis and longus (Nos. 77 and 78) respectively. 



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



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



internal condyle of the humerus and is inserted 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 brevis ulnce. 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 



Watsou) 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.
