Four skulls from the Magellan Straits. One of these skulls, apparently rather aged, has only five teeth on each side above and below, as in the genus Zalophus ; it has, however, the concave palate and other characters of this genus. There is no appearance of there ever having been a sixth pair of teeth ; but its absence is no doubt only an individual variation. 4. ARCTOCEPHALUS AUSTRALIS, Zimm.1 The skin of a young specimen " six weeks old," and five skulls from the Magellan Straits. 5. HESPEROMYS (CALOMYS) COPPINGERI, sp. n. A skin from Tom Bay, and two specimens in spirit " caught with trap on a wooded islet about one acre in extent " in Cockle Cove, (Feb. 9, 1879). Fur very long and soft, fully half an inch in length on the back. Ears rather short, nearly hidden in the fur. Whiskers of medium length, the shorter lower ones forming a thick shining white fringe along the upper lip. On the head and back the wool-hair is of a deep slaty blue for nine tenths of its length; then follows a subter-minal band of yellow ; and the extreme tip is black. Mixed with Fig. 1. Fig. 2. Left ear of Hesperomys coppingeri. Right foot of Hesperomys coppingeri. this wool-hair there are a considerable number of longer black hairs, the resulting general colour being very similar to that of the common Water-vole {Arvicola amphibius, L.). The dark colour of the upperside extends on the limbs to the wrists and ankles, the feet being covered with short shining white hairs. The ears are thickly clothed with short woolly hairs similar in colour to the fur of the back. On the sides the yellow tips of the hairs gradually become lighter, and on the belly they are nearly pure white, the basal portion of the fur, however, from the chin to the anus, still being slate-coloured.
