Splenial teeth 3 In dorsal view, the posterior of the head is slightly narrower than the nuchal region. The lateral margins are almost straight and subparallel for most of their length. The positions of the tentacular apertures are visible as strong bulges. The snout in front of this is subtriangular, with the tip forming an angle of approximately 60º, gently rounded only at the extreme apex. The snout projects moderately (

The distance between the jaw angle and the top of the head is marginally greater than between the jaw angle and the ventral edge of the lower jaw. In anterior view, the ventral surface of the rostrum of the snout is flat. In ventral view, the anterior margin of the lower jaw is much more broadly rounded than the anterior margin of the snout.

The welldeveloped eye, within which a lens is visible, is covered by the anterior limit of the squamosal, and is very faintly visible through the skin externally. The surface of the eye region is level with the surrounding surface of the head. In lateral view, it is about halfway between the margin of the upper lip and the dorsal edge of the head, slightly higher on the right side than on the left. The eye is about as far from the jaw angle (

The teeth were especially difficult to examine, and our observations might be checked with better equipment. A concerted effort was made to examine the tips of the tooth crowns. The 18 dentary and 21 premaxillarymaxillary teeth appear to be monocusped. A second cusp is faintly indicated on the vomeropalatine teeth, of which 10 were counted on the left side. Three splenial teeth were counted, one right and two left. The teeth in the outer rows are notably larger than the inner rows of both upper and lower jaw, and the dentaries are the largest overall. They increase in size anteriorly, except that the anteriormost dentaries are smaller than those situated anterolaterally. The premaxillarymaxillary and vomeropalatine tooth rows clearly extend posterior to the choanae. The choanae appear quite large, and are separated by a distance that is approximately a little less than twice the transverse width of each choana.</paragraph>

Middorsally, the first is gently sinusoidal (slightly deflected posteromedially), and the second bends slightly anteriorly. The straight posteriormost nuchal groove is broadly incomplete midventrally.

The second collar bears a longer transverse dorsal groove, slightly closer to the third nuchal groove than the second.

The annular grooves are incomplete midventrally, except for approximately the last 10 annuli, and faintly indicated on the dorsum throughout. The grooves of the first 15 annuli are complete middorsally. Behind this, the grooves appear to be mostly incomplete middorsally, except posteriorly, where they are complete but very faint. The last two annular grooves are widely incomplete middorsally and midventrally, and are more faint than the preceding grooves. Posterior to the last groove, there is a long (
