C. Flammula rubro-marginata is a worthy and beautiful-leaved variety.

I. Aquifolium albo-marginata has ovate, nearly flat, spiny-serrate leaves, with a narrow silvery margin, and fruits freely.

The following list includes some of the best and most beautiful of these varieties: Alba marginata. Ardens. Astreans.

16 Aretia vitaliana Primrose aretia l. 17 Androsace villosa Hairy Androsace l. 18 Primula cortusoides Bear's-ear Primrose b.l. 19 villosa Hairy Primula b.l. 20 nivea Snowy ditto b.l. 21 marginata Margined ditto b.l.

Still some fine specimens of a curious flat sea-urchin (Encope marginata) and a few shells, encouraged us to persevere.
