the parotid (fig. 8, P. gl.) needs be mentioned, as of very large size, 
wide, flat, and coarse in texture, as, indeed, is the case throughout 
the larger Bovidee. Stenon’s duct (S¢.d.) is capacious and long, 
curves round the mandibular angle in company with the facial vein 
(F.v.), dips into the cheek-tissues, and finally opens by a papillary 
orifice close behind the angle of the mouth. In the Common Goat 
Stenon’s duct opens much further back in the mouth. There is a 
small flat glandular mass (fig. 8, G@/. s), spread thinly upon the sur- 
face of the buccinator muscle, and entirely separate from the parotid, 
though in connexion with the Stenon’s duct. This buccal gland may 
be the homologue of the so-called socia parotidis in Man, here 
thrown considerably forward, and quite isolated from the parotid itself. 
The submaxillary gland appears closely commingled with the pa- 
rotid. The sublingual gland is well developed, lies in the usual 
situation alongside the tongue, and is very elongate, corresponding 
with the shape of the latter organ. 
The large dimensions of each and all of these salivary apparatus 
is not peculiar to the Saiga; for, as is well known, in the whole of 
the ruminants it attains considerable volume. 
5. Vocal and Respiratory Tract. 
When the pharyngeal wall is cut through and reflected, the upper 
laryngeal parts present the following aspect (vide C, fig. 11) :—The 
aryteno-epiglottic folds are large, and lie outwards, giving breadth to 
the deeply excavated laryngeal opening. The glottis is an elongate 
arrow-headed fissure, wide in front and narrowed behind. The 
posterior floor or basal end of epiglottis has two parallel longitudinal 
narrow ridges, which descend towards the rimal aperture. Outside 
the aryteno-epiglottic folds and between them and the thyroid carti- 
laginous alee are deep and wide cavities (exterior laryngeal pouch, 
l. p), the posterior ends of which curve inwards. Bounding the 
narrowed hinder end of the glottis are two long narrow membrano- 
fatty projections, which unite behind and thus form a compressed 
V-figure ; these (lettered s.p, in cuts A, B, D, fig. 11) are eminences 
produced by thickened tissues surmounting the upper border of the 
cartilaginous plates of Santorini, or, possibly, combined with these 
cuneiform cartilages. With its side folds, the epiglottis looks full, is 
somewhat triangular in outline, and less than an inch in its dia- 
meters. 
A deeper dissection of the upper laryngeal cavity, as in the side 
view B and upper view D, shows that this is capacious, and that 
the walls, both laterally and in front, are padded with fatty matter 
(f). This, with its mucous lining, forms numerous thick longitu- 
dinal folds ; and quite in front is a sulcus, which, descending, leads 
into a small pouched cavity within the depending globosity of the 
thyroid cartilage. This recess, hidden by the folds spoken of, is 
slightly locular or gland-pitted within. The chink of the glottis (g), 
commencing immediately behind this pouch, has an antero-posterior 
diameter of 2 inches. Its anterior half is bounded by two consider-
