Itfitscles of Salamander terrestris. pubis and partly from the outer border of the Y-shaped pelvic cartilage, whence it rims forward along the whole length of the abdo- men, enclosed in a sheath, formed between the internal and external oblique muscles of the abdomen as far as the throat, where it is inserted into the middle cornea of the os- hyoides. The rectus abdominis (fig. 208, 8) takes its origin entirely from the Y-shaped pelvic car- tilage, and, first attaching itself to the trian- gular lower rudiment of the sternum, over which it passes, it becomes again connected with the upper transverse piece of the ster- num, from whence it sends a slip forwards to be inserted into the centre of the lower jaw : this last portion represents the genio-hyoi- deus. In its course, this muscle is divided by several tendinous intersections. It is, more- over, attached with some firmness to the pericardium, in the neighbourhood of which it gives off two additional slips of muscle, one of which passes obliquely outwards to join the pubo-hyoid ; the other (10) runs to be inserted into the scapula, becoming like- wise connected with the scapulo-humeral articulation. The mylo-hyoideus (fig. 208,11) fills up the entire space betwen the arches of the lower jaw, from the angle of which, likewise, arise two cutaneous muscles (fig- 207, 12) and (fig. 208, 13), one of which extends into the skin of the inferior and anterior region of the neck, whilst the other mounts backwards and out- wards to be similarly inserted into the skin upon the sides of the cervical region. A muscle (fig. 208,14) passes from the lower jaw near its symphasis, to be inserted into the extremity of the anterior cornu of the os- hyoides ; whilst a second slip
