Character.-Zoarium dichotomous, 2 to 3 inches high, composed of unequal internodes, sometimes much elongated, sometimes short and thick; joints nodular. Areas hexagonal or pyriform when young; surface smooth, no interior ridges. Orifice crescentic, transversely elongate. Operculum semicircular or subcrescentic, angular, apparent foramina small. Avicularia vicarious; mandible spear-shaped, with a very wide base and large inferior foramen; apex acuminate, incurved, 0"013 x 008 to 0"0095 X 008.

Station 315, lat. 51° 40' S., long. 57° 50' W., 12 fathoms, sand and gravel. Station 176, lat. 18° 30'S., long. 173° 52' E., 1450 fathoms, Globigerina ooze. Port William, Falkland Islands; 5 to 10 fathoms. [South Patagonia, Falkland Isles, Strait of Magellan, Darwin; Mount Gambier (fossil), Waters.]



Salicornaria malvinensis presents considerable diversity of habit in different localities, so much so, that at first I had designated one of its varieties, characterised by the shortness and thickness of the internodes and the comparatively large size of the orifice, Salicornaria megastoma; but further examination has shown no essential differential characters between this and the forms with elongated and slenderer internodes. In the variety from Station 315 (fig. 7) a further exception to the more usual character is seen in the granular surface of the interareolar septa, when the epitheca has been removed.
