gulare, lies between the distal end of the radius and the styloid pro- 

 cess of the ulna, proximal to the joint cavity of the wrist and anterior 

 to or in the triangular fibro-cartilage. 2, Pkiforuie seaui'Jariuni, a 

 proximally directed derivative of the Pisiform, which articulates with 

 the cuneiform. B. Proximal row : 3, Naviculare radicde, the 

 larger radial half of the semilunar. 4, Naviculare ulnare, the smaller 

 ulnar half of the semilunar. 5, Limahcm j^rojminn, the chief mass 

 of the semilunar, excluding Epilunatum and Hypolunatum. 6, Tri- 

 qiietram radiale, the radial half of the cuneiform. 7, Triquetnim 

 idnare, the ulnar half of the cuneiform. 8, Pisiforme projrrmrn, the 

 normal pisiform. C. Central row : 9, Ra<liale externum, placed to 

 the radial side of the tuberosity of the scaphoid and articulating with 

 the trapezium. 10, Eintrappzium, lying on the dorsal surface of the 

 trapezium, near the scaphoid. 11, Centrale volare, the volar and 

 more radial half of the centrale, intruding itself from the dorsum 

 between the scaphoid, trapezoid, and os magnum. 12, Centrale dor- 

 Kale, the dorsal and more ulnar half of the centrale. 1 3, U2^ituna- 

 tum, the distal, dorsal, and radial angle of the .semilunar, lying on the 

 dorsal surface between semilunar, scaphoid, and os magnum. 14, 

 Hypolunatum, the distal, radial, and volar angle of the semilunar, 

 lying on the volar surface between scaphoid, semilunar and os mag- 

 num. 15, Epipyramis, the distal, dorsal, and radial angle of the 

 cimeiform, lying dorsal between cuneiform, semilunar, and unciform. 

 16, Ulnare externuin, on the dorsal surface of the triquetrum ulnare, 

 near the unciform. D. Distal row: 17, Trajjezium proprium, the 

 principal mass of the trapezium : the normal trapezium, excluding 

 paratrapezium and Tr. secundarium. 18, Trape-ioides iiroiivium, the 

 volar part of the trapezoid, reaching the dorsum of the hand proxi- 

 mally. 19, Metadyloid, dorsal- between trapezoid, os magnum, and 

 the styloid process of metacarpal iii. 20, Gapitatum proprium, the 

 principal mass of the os magnum : excluding C. secundarium and 

 subcapitatum. 21, Hamatum propi'iura, the unciform, excluding its 

 hook. E. Carpo-metacaepal row : 22, Paratrapezium, the disto- 

 radial angle of the trapezium : pushing itself in from the radial aspect 

 of the hand between the trapezium and the i. metacarpal. 23, Prae- 

 trapezium, Volar : at the distal end of the tuberosity of the trapezium, 

 between it and the metacarpal i. 24, Trapezium secundarium, the 

 disto-ulnar angle of the trapezium, lying between trapezium, trapezoid 

 metacarpal i. and metacarpal ii. 25, Trapezuides S'cundarium, dorsal : 

 lying between trapezium, trapezoid and metacarpal ii. 26, Epitra- 

 /jezoideum, the dorsal half of the normal trapezoid : larger than that 

 bone, but ])urely dorsal : lies between the trapezium, os magnum, 

 metacarpal ii. and the styloid process of metacarpal iii. : is separated 

 from the scaphoid by the dorso-proximal angle of the trapezoides pro- 

 prium. 27, Parastyloideum, dorsal: between trapezoid, metacarpal 

 ii. and styloid process of metacarpal iii. 28, Slyloidemn, the styloid 

 process of the iii. metacarpal : dorsal : lies between metacarpal iii., 

 metacarpal ii., os magnum, and trapezoid. 29, Sidjcapiiatum, the 

 volar part of the distal end of the os magnum : lies volar between 

 the head of os magnum, trapezoid, unciform, and metacarpal iii. 30,
