    nus and parvus) and then invests the aorta, vena cava and sympathetic nerve trunks (Fig. 2). As it lies over the quad, lumb. and psoas, it also covers and invests the twelfth tho- racic nerve (ant. ramus) and the descending branches of the lumbar plexus. This portion, furthermore, passes behind the kidneys, adrenals, oesophagus, pancreas and duodenum. At the anterior edge of the quad. lumb. it sends off a very delicate lamina which goes behind the muscle, i.e., between it and the posterior tendon of the trans. abd. Before tracing upward those portions of the transversalis fascia which cover the psoas and quad. lumb. muscles, the following will be in order. Each crus of the diaphragm has a narrow median border of tendon which unites with the one of the opposite side across (ventral to) the aorta forming the middle arcuate ligament from which some of the muscular fibers of the diaphragm arise. From this tendinous edge of each crus, at about the level of the disc between the first and second lumbar vertebrae, is prolonged laterally another nar- row tendinous edge which curves across the psoas (the latter going up behind it), to be attached close to the tip of the transverse process of the first lumbar vertebrae. This is the medial lumbocostal arch, from which also muscular fibers of the diaphragm arise. Another similar tendinous edge arises from where the first one ends and crosses the quad. lumb. to be attached to the twelfth rib just beyond the line of attachment to this rib of the quad. lumb. This is the lateral lumbocostal arch and it also gives origin to muscular fibers of the diaphragm. These lumbocostal arches are also called medial and lateral arcuate ligaments. Counting with them the middle one, the five make a continuous edge to the diaphragm like the selvage of a piece of cloth. Tracing the transversalis fascia upward: this narrow tendinous edge is held closely to the quad. lumb. psoas and
