Show 876 MR. ST. GEORGE MIVART ON THE [DeC. 6, upper part of the shaft of the femur, passing beneath what I have distinguished as the first part of the gluteus medius, and just below and slightly tibiad to the insertion of what I have called gluteus minimus.

Vastus internus. Gluteus maximus (figs. 2, 17, & 27, X). This name has been applied by me in the Iguana*, Menopomaf, and Menobranchus J, to a muscle which, on further consideration, seems to me can have little claim to it. On the other hand, I think that the muscle which I called pyriformis in the Iguana§, answers to the one I am now about to describe in the Chameleon, and which has a considerable resemblance to that which I designated as gluteus maximus in theEchidna||. It arises, in Parson's Chameleon, from the transverse processes of the more anterior caudal vertebrae, and is inserted into the tendinous arch which passes from the posterior margin of the ilium to the tuberosity of the ischium. It is blended posteriorly with the transversus perinei, and, but for the tendinous arch, would be continuous with the biceps, thus strongly resembling the gluteus maximus of the Echidna. * P. Z.
