For the opportunity of examining the collection made during the voyage of the 'Valorous,' I am indebted, as on many similar occasions, to Dr. Gwyn Jeffreys, the scientific chief of the expedition. The specimens were not quite in such good preservation as those collected, for instance, in the dredging expeditions of H.M.S. 'Porcupine,' and Dr. Jeffreys's yacht 'Osprey,' since specially prepared bottles and spirit were sent on these occasions. No group of marine Invertebrates is more difficult to preserve in a satisfactory manner than the Annelida; and it may not be inopportune again to draw attention to the necessity of pursuing, as far as possible, the method indicated below.
