Body oval in shape, compressed, dorsal profile rising from snout with a concavity and is less convex than the ventral profile. Snout pointed. Interorbital space concave, bounded by two ridges which continue as the outer edges of nuchal spine. The median portion is elevated, about 2 in head. One small spine on head, immediately above eye and opposite its front border from where the ridge bounding the interorbital space commences. Mouth when protracted forms a tube directed upwards, gape of mouth opposite middle of eye and the tip of maxilla far in front of the front border of eye. Mouth small, lips broad and thin, lower lip smaller and broader than upper which is like a ring over the lower. Lower margin of lower jaw slightly concave, at right angles to mouth slit.
