Longit. 41 millim., diam. 2 2 ; apertura 14 longa, 9 lata. Hab. In shallow water near Sea Point, Cape of Good Hope; Natal (Krauss). This is a strong, solid shell, entirely white within and without, and ornamented with numerous spiral ridges, which are somewhat regularly alternately larger and smaller, the intervening grooves being merely incised striae. The outer lip is well thickened and armed within with about ten lirae, which, however, do not extend very far within the aperture. It does not compare with any other species. In form it somewhat resembles Euthria lineata from New Zealand, but is altogether different in sculpture and the mouth characters. JE. magellani, Velain, has a somewhat similarly thickened labrum, but is altogether different in other respects. 3. TURRITELLA INCOLOR. (Plate XXXIV. fig. 3.) Testa elongata, turrita, acuminata, alba; anfract. convexiusculi, carinis duobus mediocriter acutis circa medium instructi, liris paucis supra, inter, et infra carinas cincti, ultimus inferne liris concentricis paucis ornatus ; apertura subrotun-data ; columella parum curvata, vix rejlexa. Longit. 14 millim., diam. 5 ; apertura 3^ longa, 2\ lata. Hab. Royal Sound, Kerguelen Island, 28 fathoms. The two keels stand out conspicuous, and there is a finer liiation above them, one between the two keels and one below them. The single specimen consists of about ten whorls. It is less slenderly tapering than T. hookeri, Reeve, which, besides the two prominent spiral keels, exhibits only the faintest trace of spiral strise. 4. CAPULUS COMPRESSUS. (Plate XXXIV. figs. 4, 4 a.) Testa dextrorsa, alia, pileiformis, lateraliter compressa, planata, tenuis, alba, epidermide decidua ftavescente induta, lineis incrementi subfortiter striata; anfractus 2-3, celeriler cres-centes, duo supremi parvi, vitrei, regulares, convexiusculi, nitentes, ultimus maximus subunguiformis, supra et infra planatus; apertura oblonga, angusta. Diam. maj. S\ millim., alt. 2\ ; apertura 5 longa, 2 lata. Hab. Station 311. Off west coast of South Patagonia in 245 fathoms. No described species appears to approach that now before us. Judging from its compressed character it is probably either parasitic upon something with thin filaments or stems (the cirri or rays of a crinoid for example), or it would be found attached to the stems of seaweed. |
