suggests, that is the case, the muscle described by him as 

 a Ghiteus Miuimus is iu reality a Gluteus Medius aud 

 Minimus combined. I think there is every evidence that 

 such is the case. 



My dissection of the manus of Tachyglossa differs con- 

 siderably from that which Mivart describes and figures. 

 In the first place, he states, that of the five smaller ten- 

 dons, formed by a division of the great tendon of the 

 Flexor Communis Digitornm, all, with the exception of 

 that to the thumb, are bound down by a ligament. 



In the specimen which I dissected, the tendon of the 

 pollex passed under a ligament, similar to that of the 

 other diijits. The Abductor Pollicis, which Mivart de- 

 scribes as " Some muscular fibres " which " arise from the 

 Trapezius, and are inserted into the radial side of the 

 Pollex," was in my specimen a well developed muscle. 



M. Flexor Brevis Pollicis. 



A well developed muscle of uniform size, represents 

 in function a Flexor Brevis Pollicis. It arises from the 

 combined flexor of the wrist (Flexor Communis Digit- 

 ornm), on the radial side of the flexor tendon of the 

 pollex. It separates from this tendon, passes parallel 

 with it, and is inserted into the radial side of the pollex, 

 proximally placed to the insertion of the tendon of the 

 l^ollex, which comes from the Flexor Communis Digitornm. 

 Its origin from the tendon of the Flexor Commnnis Dig- 

 itornm, recalls to mind the origin of the same muscle in 

 human anatomy, from the annular ligament. 



M. Flexor Brevis Digitorum. 



The Flexoi* Brevis Digitorum is represented by a small 

 muscle below the plantar fascia. It arises from a bone
