    arising from the whole outer surface and upper margin of the ilium as far down as the acetabulum, as also from the sacrum and several caudal vertebrae. It is inserted into the great trochanter. The tensor vagina femoris is thick though small. It arises from the anterior inferior spinous process of the ilium, and is inserted into the fascia as usual. This muscle does not lie here so superficial as ordinarily, but is somewhat wedged in between the glutei and iliacus (fig. 11, T. v.f.). It has been described by Meckel* as the sartorius. The psoas magnus is a stout muscle, arising from the fronts of the bodies of the last dorsal and all the lumbar vertebrae, and from the bases of the transverse processes of the lumbar vertebrae. Insertion, into the small trochanter (fig. 10, P. m.). The psoas parvus has attachments upon the fronts of all the lumbar vertebrae, and is inserted by a long tendon into the ilio-pectineal ridge. Its proportion to the psoas magnus seemed to us larger than as described by Meckelf. The quadratus lumborum is very long and narrow, arising from the sides of the bodies of the last twelve dorsal vertebrae and from the heads of the ribs, also from the transverse processes of all the lumbar vertebrae, and from the anterior part of the sacrum. It is inserted into the sacro-iliac synchondrosis. The iliacus is a moderate-sized, laterally compressed muscle, arising from the anterior superior spine of the ilium, and the margin between it and the anterior inferior spine; it is inserted into the lesser trochanter (figs. 10 & 11, I.). The coccygeus arises from the spine of the ilium, and, spreading out in a fan-shaped manner, is inserted into the caudal vertebrae (fig.9,C). Although the tail is so extremely rudimentary, yet the pubo-coc- cygeus is distinctly developed as a delicate band of muscular fibre arising from the pubes behind the symphyses, and inserted into the caudal vertebrae. This muscle is not noticed hy Meckel. (Fig. 9, P. c.) The pyriformis is very closely connected with the gluteus minimus, appearing as it were to wrap round it at its lower part; so that the line of demarcation is not easily ascertained. It arises from the ven- tral surface and outer border of the sacrum, immediately behind the sacro-iliac synchondrosis, and is inserted into the great trochanter in union with the gluteus minimus, as Meckel J describes. The quadratus femoris, as justly observed by Meckel §, is very voluminous (fig. 10, Q.f.). It arises from the front part of the tuberosity of the ischium, and is inserted into the line between the greater and lesser trochanters. The gemellus superior extends from the spine of the ischium to the trochanteric fossa. The gemellus inferior has the following attachments, viz. from the surface of the ischium, near the tuberosity, to the trochanteric fossa (fig. 9, G.L). The obturator internus is rather a small muscle, arising from the * Loc. cit. p. 399. f Loc. cit. p. 368. % Loc. cit. p. 361. § Loc. cit. p. 365. [17]
