Its fibres run backwards overthis body and descend between it and the middle temporal muscle. In this coursethe fibres lie posteriorly to the suspensory ligament, and the outer ones, as theyfold about the articular end of the gland, lie in contact with the prolongation ofthe external lateral articular ligament upon that body. Finally, the milscle windsaround the commissure of the lips, and is inserted into the lower jaw some distancein front of the angle of the lips at h, Fig. 4. The middle and posterior temporal muscles.

Asthese two latter muscles descend nearly vertically, their obvious function is toclose the jaws. The use of the anterior temporal is in part also the closure of thejaws, but its more obvious oflQce is to press upon the poison gland, as we shallpresently see. The poison gland of the Crotalus occupies the side of the head, behind the eye,and beneath the anterior temporal muscle, Fig. 5. Its posterior extremity extendsthree or four lines beyond the commissure of the lips. Its anterior end lies belowand just behind the e3e. Thus situated, the gland is in relation with the bonysurface behind the eye, with the middle temporal muscle, with nerves which emergeunder the suspensory ligament, and with the
