Scincus Mitranus, n, sp.* 
Head rather small and much pointed ; tail short and thick at the 
base. Snout contracted behind the nostrils and dilated in front of 
them, sharp, spatulate and fossorial. Nasal crescentic, occupying 
the place of a first superior labial, but with the lateral portion of 
the rostral below it, in contact with the rostral, first labial, anterior 
loreal, large supranasal and small internasal. The supranasals 
large, not contiguous, pentagonal, four of their sides large and one 
very small, in contact with the internasal, Internasal small, round- 
ed, lying between the rostral, nasal and supranasal. Rostral witha 
broad, rounded, sharp anterior margin ; its sides much convergent ; 
its posterior end forming only a narrow suture with the frontal ; 
its under surface broad and slightly shelving upwards ; its posterior 
margin a crescentic, cutting ridge, defined from the surface anterior 
to it, by a deep groove. The frontal large, conical from behind 
forwards, and pointedly unguiform, forming sutures with the ros- 
tral, supranasal, anterior loreal, and contiguous by its hinder mar- 
gins with the post frontals. Post frontrals large, pentagonal, broad 
in front, pointed behind, forming a broad suture together. Vertical 
of moderate size, rather narrow, its anterior margins forming an ob- 
tuse angle; lateral margins concave and slightly convergent; abruptly 
truncated posteriorly. Two pre-occipitals rather small,oblongly pen- 
tagonal, placed obliquely, and contiguous. Occipital considerably 
_ smaller than the vertical and wedge-shaped from before backwards : 
two rather large scales placed transversely along its external 
margin. Two small postoccipitals. Five large superciliaries with an 
internal line of four small plates, the first of which equals the length 
of the three succeeding ones. Four rather large scales form the 
lower margin of the eye, the anterior scale as long as the two be- 
hind it. Loreal region concave. Two elongated loreals one before 
the other, the anterior shield in contact with the supranasal, nasal 
and three lower labials. Hight upper labials, the two below the
