The anal opening in the shape of a slit is situated close to the anal fin. The branchiostegal membrane
is provided with 15 rather short rays. The edges of the jaws are cutting, along their entire length packed
with a series of rather small teeth, the free tips of which are very sharp and somewhat inward curved.
Rostrally on the lower jaw two patches of similar shaped teeth are placed opposite the transversely placed
series of teeth on the vomer. From these teeth a rather broad band, densely packed with acutely pointed
teeth, runs along the outer edge of the palatine bones extending backwards. This band at a third of its
length mixes with a large patch of very fine granulated teeth that occupies the entire surface of the palate.
The inner side of the gill arches as well as the gill rakers are covered with densely packed small teeth. The
same is true for the surface of the hard element that supports the tongue, but the tooth-like elevations of
this part, especially in the centre, are larger and rounded at their tips (fig. 4) The tongue has an elongated
shape, as one can see from this element which serves as a support, it tapers a little rostrally and it is
rounded at its tip. The element itself is edged with a fleshy margin, which is almost half of its width.
