20 Leach, The Myology of the Bell-Magpie. [i.f""!)- 



87. The flexor minimi digiti [28] arises fleshy from the posterior 

 side of the upper end of the metacarpal, and is joined by a distinct 

 branch from the ulna. It runs down a groove provided for it, 

 and the delicate tendon is inserted into the base of the phalanx 

 of the medius finger. 



88. The flexor minimi digiti brevis [28], a fleshy, rudimentary 

 muscle, arises from the distal posterior aspect of the metacarpal, 

 becomes tendinous, and is inserted at the apex of the phalanx of 

 the medius. * 



89. The abductor minimi digiti [28] is a small rudimentary 

 muscle — indeed, almost a ligamentous band. It arises from the 

 anterior proximal aspect of the medius digit, passes outwards, 

 and is inserted upon the posterior edge of the proximal phalanx 

 of the index finger. 



90. The flexor metacarpi brevis [27] arises partly fleshy and partly 

 tendinous from the outer side of the distal extremity of the ulna 

 in the superficial fascia to which the primary wing quills are 

 bound. The fleshy part soon ceases, and the delicate superficial 

 tendon runs obliquely down the carpo-metacarpus to be inserted 

 at the base of the proximal phalanx of the index finger on its 

 ulnar side in front. This is not an easy muscle to dissect. The 

 tendon runs so superficially that there is danger of removing it 

 when the primaries are freed from the hand, to which they are 

 so firmly lashed. 



91. The interosseous dor salts [27] is the outer and higher of two 

 flat paper-like muscles that are found in the long vacuity in the 

 index and medius metacarpal, as described by Shufeldt for the 

 Raven. It sends a slender tendon in a shallow groove to be 

 inserted at a point on the anterior aspect of the base of the distal 

 phalanx of the index digit. 



92. The interosseous palmaris [27] lies in the same vacuity under 

 and more distally than the interosseous dorsalis (91). Its tendon 

 passes more posteriorly to the outer side of the index digit even 

 to the apex of that digit. 



THE MUSCLES OF THE LOWER EXTREMITY. 



Shufeldt named 30 muscles in the lower extremity of the Raven. 

 I find in Strepera and the Australian Raven one additional 

 muscle, the gluteus quartns of Mayer, quoted by Owen. Shufeldt 

 named the thigh muscles as follows : — 



93. The sartor iiis. 



94. The gluteus primus. 



95. The glutetis medius. 



96. The gluteus minimus. 



97. The extensor femoris (crurcpits, vastus externus). 



98. The vastus inter nus. 



99. The biceps flexor cruris. 

 100. The semitendinosus.
