44 SOLENODON PARADOXUS. 
third begins at the anterior corner of the first premolar on each side and is 
bowed forward; the fourth and the fifth arise on the palate at the base of the 
second and third premolars respectively; finally, the sixth, seventh, and eighth 
join the anterior edges of the first, second, and third molars respectively. The 
amount of bowing forward varies slightly. Brandt, in his original account 
figures but seven, and Dr. J. A. Allen has recently described the same number 
in the specimen at New York. These may represent actual variations or, as 
seems probable, one of the folds may have become relaxed and thus have dis- 
appeared through partial maceration. It is the smallest and anteriormost fold 
that is lacking in Dr. Allen’s specimen. Peters figures nine transverse folds for 
S. cubanus. 
The tongue (Plate 9, fig. 4) is long, narrow, and tapering. It is free at the 
tip for about 19 mm., and closely resembles that of the Cuban Solenodon in 
the character and distribution of the papillae. These are of three principal 
kinds: first, the fungiform papillae, that are scattered over the surface of the 
tongue from the muscular prominences at its root, where they are most numer- 
ous, to the tip; they are white, and either round columnar projections or ex- 
panded at the top, and project conspicuously from the surface of the tongue; 
secondly, the cireumvyallate papillae of which there are three, one circular and 
median, just posterior to the swellings at the root of the tongue, and two oval, 
one on each side and slightly in advance of the median papilla; in Gymnura 
there is no median circumyallate papilla; and thirdly under a lens, the surface 
of the tongue is seen to be thickly covered with minute pointed filiform papillae, 
which become larger and flattened with appressed and backwardly directed 
points in the region of the circumvallate papillae. There is a slight median 
groove at the tip of the tongue. ; 
The epiglottis is short and cartilaginous, with a prominent median process 
anteriorly. 
The salivary glands (Plate 5, fig. 1, p, s) are large and prominent. The 
parotid is the most conspicuous and lies behind the masseter muscle and the ear, 
with a forward prolongation nearly to the orbit in one specimen examined. Its 
duct is with difficulty traced from a point below the ear, forward parallel to the 
roof of the mouth to about opposite the first molar. The submaxillary gland 
consists of two portions as in Gymnura, one slightly more median, posterior 
to the angle of the jaw. Both are oval, smaller than the parotid, and slightly 
darker in color. In Centetes, this gland is in three divisions. _Wharton’s duct 
may be traced from the deeper portion of the gland near its center, forward, 
along the inner side of the ramus to the root of the tongue.
