Show 272 PROF. ST.-GEORGE MIVART ON THE [Feb. 21, evenly with small, fine, soft conical papillae directed backwards. Amongst them a few round fungiform papillae are scattered; but these become much more conspicuous on the intermolar eminence. There is no sublingua. The salivary glands are very largely developed. The parotid is exceedingly large and of very loose texture, its very numerous lobules being very much scattered and in part loosely coherent. It is arranged in two superimposed layers in folds of gland-substance, and extends over the whole side of the neck, where it forms a large mass dipping into a triangular cavity above the cleido-mastoid muscle, between it and the levator clavicula, and even a little beyond the clavicle. Its anterior margin is strongly concave forwards, extending almost as far anteriorly Fig. 1.

Its duct runs forwards across the masseter muscle, just below and parallel with the lower border of the zygoma, to open beside the anterior molar tooth. The submaxillary is large and of very similar texture to, but only between ? and i the size of the parotid. It is pyriform in shape, lying beside the inner border of the masseter, and separated from its fellow of the opposite side by the sternohyoid muscles. Its duct runs forwards along the inferior margin of the masseter muscle to end as usual. The length of the submaxillary is about 2"*4 its breadth about 1"*5. The gland is almost divisible into two parts |
