c.f. Caryocaris acuta Bulman (pars). 1931, p. 85, text-fig. 41 (upper figure).

Observations.—There appears to be a general resemblance of Dr Bulman's figure, quoted above, to the present specimen. From its elongate-ovate form it may be referred to the genus Lingulocaris Salter.

With regard to the surface ornament the New Zealand specimen agrees very closely with Lingulocaris siliquiformis Jones (cf. Jones and Woodward, 1892, pl. xiv, fig. 2) in having a delicate squamiform character.

Bulman's Caryocaris acuta came from the Caradocian of Peru, whilst L. siliquiformis and other allied species are from the Upper Tremadoc and Lower Lingula Flags of Wales. The present form therefore occupies an intermediate stratigraphic position between these.
