cit. p. 272) . It was also found bj Giinther and Milde (Die chirurgische 

 Muskellehre, Taf. 30. fig. 5. 18). In the right arm of a muscular soldier 

 Gantzer found a fleshy muscle connected with the insertion of the abductor 

 minimi digiti^ arising from the sheath of the Jlexor-carpi-radialis tendon, 

 to which he gave the name of the accessorius ad Jtexorem carpi radialem"" 

 {op. cit. p. 12), which was evidently a muscle of the same character as the 

 foregoing. Macwhinnie mentions similar high origins of this muscle, 

 arising from the tendon of the palmaris longusy as varieties of the last- 

 named muscle {op. cit. p. 191). This abnormal upward extension of the 

 origin of the abductor minimi digiti seems to correspond to the shortest of 

 the three muscles representing the ulnar carpal extensor found in the 

 Anteater (Meckel, Archiv, B. v. S. 45, U). In both hands of the female 

 (No. 20) the muscle was provided with a double tendon of insertion ; and 

 in the right hand of No. 33 the whole muscle was divided into two parts. 



39. Interossei manus. — In both hands of 4 males and 3 females, and in 

 the left only of one other female, the interosseiis primus volaris^^ of 

 Henle was found. In No. 4 this muscle, as before described, was connected 

 at its origin with an accessory slip of the extensor carpi radialis longior 

 (see fig. 6 d). It has been found in 12 out of 102 subjects, usually on 

 both sides. In the males (Nos. 3 & 4) the first dorsal was separated 

 into two muscles, the abductor and interosseus prior indicis of Albinus. 



40. Sundries. — Besides the scapulo-clavicular and chondro-coracoid 

 muscles described in the former part of the paper, in subjects 4 and 13, 

 this column marks in the male (No. 7) an abnormality of the infra-sca- 

 pular muscle, which consisted in a separate origin and distinct superficial 

 position of the fibres derived from the spine of the scapula. In the right 

 arm of the female (No. 21) the supinator longus received a large muscular 

 slip from the extensor carpi radialis longior^ as described with the abnor- 

 mality of the latter muscle. On the right side of No. 35 two large fleshy 

 slips from the ninth and tenth ribs, and on the left side from the eighth 

 also, quite separate and somewhat distant from the rest of the serratus 

 magnus, were inserted into the lower angle of the scapula, with the lower 

 fibres of that m.uscle, which reached no lower than the seventh rib. This 

 differentiation of the lower fibres of the serratus resembles the depressor 

 scapulcB muscle found in the Birds. The female (No. 36) was remarkable 

 for the very rare absence, in the right hand, of the palmaris brevis muscle. 



The remaining sixteen columns are occupied by the abnormal muscles of 

 the Leg. The additional lines of variation are partly composed of muscles 

 which have not been before especially regarded (such as the pyriformis, 

 gemelli, and opponens minimi digiti) and partly of more numerous speci- 

 mens of abnormalities presented by those which were before comprised in 

 the column of sundries (as the plantaris, peroneus brevis, and adductor 

 hallucis). 



41 & 42. Pyriformis and Gemelli. — In 3 males and 1 female the ten- 

 don of the pyriformis was blended with that of the obturator interims
