262 Prof. J. C. Galtou on the Myology 



The lumlbricales were three in numlber. Thej arose from 

 the common tendon of the flexor commmiis, at the angle of 

 origin of the branches destined for each toe. They appeared 

 to pass to the tibial sides of the three outermost toes, and to 

 terminate by delicate tendons at the point where the deep 

 flexor tendons are bound down to the toes by ligamentous 

 straps. Meckel makes no reference to them, nor does Cuvier 

 figure them. 



The interossei were very well developed, being stronger 

 than those of the palm. They were seven in number, and 

 arose from the plantar surface of the second row of tarsal 

 bones. Each ended in a broad tendon, which joined on either 

 side the extensor tendon of its proper digit. Each toe, the 

 fifth excepted, had one on either side, the latter only on its 

 fibular side. The hallux had none. On the extensor surface 

 of the foot, from the ligament connecting the astragalus with 

 the ento-cuneiform bone, and from the side of this latter, 

 passed a muscle to the tibial side of the proximal phalanx of 

 the second digit. This is the tibial interosseus of the second 

 digit. 



Superficially, on the plantar aspect of the foot, lies a large 

 muscle, which is attached on one side to the strigil bone, and 

 on the other to the metatarsal tubercle of the fifth digit, as 

 Avell as to a ligament passing from this to the calcaneum. 

 This muscle seems to Q.oxxQ,s\)Oii(\.^ functionally at any rate, to 

 the large palmar muscle which is attached to the pollex and 

 to the pisiform bone. 



The ligamentum teres of the hip-joint was well developed. 

 It is absent inBradypus^ according to Prof. Macalister {loc. cit. 

 p. 0)6) and according to Meckel, liapp {op. cit. p. 45) remarks 

 that it is absent in the Sloths and the Manis. 



Though the carpal and tarsal bones of the Tvvo-toed Ant- 

 eater have been described both by Meckel and Cuvier, I am 

 not aware that they have ever been figured in detail ; for 

 though there is an excellent representation of the complete 

 skeleton of the animal in Dc Blainville's ' Ostdographie,' tlie 

 number and arrangement of these bones can by no means with 

 certainty be determined. I have therefore thought it advisable, 

 notwithstanding that my paper professes to deal with myology 

 only, to add a plate comprising figures of the fore and hind 

 pav/s and the carpal and tarsal bones of this curiously modified 

 Anteater.
