S O W E R B Y } Jun. [Received January 8, 1883.] (Plate VII.) LIMA GOLIATH, sp. n. (Plate VII. fig. 3.) Shell rather obliquely oval, white, semitransparent, striated at the sides and on the auricles, otherwise smooth; anterior side with a depressed lunule, making a straight outline extending from the umbones about half the length of the shell; thence the outline is curved; umbones acute; cardinal area deeply excavated; anterior auricles small and very sloping, posterior large; valves nearly closed on the hinder side, slightly gaping in front. Long. 150, lat. 110 mill. Hab. Japan. This magnificent species, the largest of the genus, appears to have been hitherto undescribed. It is of stouter substance and not so inflated as the Norwegian species (L. excavata). Its surface is smooth, excepting at tbe sides, which are rather roughly striated. The cardinal area is larger and deeper than in the specimens before m e of L. excavata. This specimen was sent to m e from Japan, and now belongs to the rich collection of Dr. Prevost, of Alei^on. Another specimen has recently been brought by Dr. Hungerford from Japan, the latter being a very old shell, larger and thicker than the type, with its surface much eroded and worm-eaten.
