I am indebted to the courtesy of Dr. Allen for the opportunity of examining the collections of these two orders of Crustacea in the Huxley's material.

None of the species are new to science, and but few of them present any features worthy of remark. The chief interest of the collection lies in its bearing on the known geographical distribution of the species captured for, out of a total of twenty-eight, no fewer than sixteen are recorded for the first time from localities south of the British Islands, while only eight of the species have previously been recorded from the Bay of Biscay. The bathymetrical range of five of the species recorded has been considerably increased by this material.
