Only Norman's spec, had 4 teeth (as in the typical H. quadridentatus). The length of the species is abt. (11) iH—20 mm. Halirages quadridentatus (Chart 48, partim (p. 265)). (On the literature ami remarks on morpho- logy, see above). Occurrence. The species was only once secured by the 'Ingolf'; but it has been taken several times in the area.
