Lot'ol'dleH.—West Indies; between Delta of the Mississippi and Cedar Keys, Florida; off Fernandina, Florida. Depth. —227-273 fathoms. Body ol)long-ovate, al)out two and a half times longer than Avide, 10 mm.: 25 mm. Head, two and a half times wider than long, 2 mm.: 5 mm.; tri- angular in shape, the front produced over ^ the basal articles of the antenna?. Eyes large, composite, oval, and occupying a large part of the dorsal surface of the head, being xery close together in front, but not contiguous. Basal article of tirst an- tenna small and almost entirely concealed by the front of the head; second article twice as long as first; third article nearly twice as long as second. Flagellum is composed of six articles. The tirst pair of antennie extend to the end of the peduncle of the second , or to the antero-lateral angle of the tirst tho- racic segment. The second pair of antenna' have the first two articles short, the tirst article a little longer than the second; the third is twice as long as the tirst; the fourth is but little longer than the third; the fifth is one and a half times longer than the fourth. The flagellum is composed of fifteen articles. The second antenna^ extend to the pos- terior margin of the second thoracic segment. The frontal lamina is small and almost inconspicuous. It is rhomboid-shaped at the base and ventrally placed. The maxilliped has a palp of two articles. The first three segments of the thorax are subequal; the fourth is slightl}' longer than any of the preceding* ones; the last three are the largest. The epimera are distinct from the segments. They are narrow plates, with the posterior extremities very
