At the lower O third of the bone their fibres converge to a point, tobecome attached to a strong and powerful tendoncommon to the two divisions; this, passing through theoblique, fibro-cartilaginous bridge just above the tibialcondyles, goes directly, in the antero-median line, toa point on the shaft of the tarso-metatarsus just belowthe head of that bone, where it is finally inserted upona tubercle, there found, and which is intended for it. Both the peroneus longus and the tibialis anticus arewell developed in such a bird as Geococcyx californianus,and have essentially the same origins and insertions as Vorderer Schienbeiumuskel.

We have good views of them in Fig. 62 bis ofthe present work. Several years ago I devoted no littleattention to the myology of Geococcyx, and publishedmy observations thereon in a number of places. Thebird, as is well known, occurs on the Pacific coast regionof the United States, and presents much of interest inits anatomy. It is a big Ground Cuckoo with affinitiesin other directions. To become impressed with the great number ofchanges to which this muscle is subject, we can do nobetter than to read Prof
