II.—Description of two new species of Stricklandinia

Abstract

In the “Canadian Naturalist and Geologist,” vol. iv. p. 134, figs. 8–9 (1859), I figured a small specimen of a species of Stricklandinia under the name of S. lens; but, at the same time, stated that I was not certain whether it was the true S. lens or a variety. It was more pointed in front than any of the English specimens I had seen. It had been collected in the Middle Silurian rocks on the Island of Anticosti, along with numerous other specimens, most of them in a fragmentary condition. Among these I thought that S. lirata could also be identified; and thus both of the British species have been cited in several of the publications of our Survey.
