Deplli of body C)\ to 8 times in total length, lenf^th of head 4.\ to 5 times. Head about once and a half as long as broad, smooth or very feebly granulate above ; occipital process angular; occipital fontanelle as large as or a little smaller than the frontal, and j)artlyon the occipital process ; eye very t^niall, 2 to 3 times in length of snout, 5 to G times in inter-orbital width ; vomerine teeth granular, forming a crescentic band which is as broad as or a little narrower than the band of pra.'maxilhiry teeth. Nasal barbel nearly once to once and a half length of head ; maxillary barbel once and I to twice length of head, reaching extremity of pectoral fin or beyond. 16 to 18 gill-rakers on anterior arch. Dorsal 82-91, its distance from the occijjital process nearly ;■( length of head. Anal G8-72. 13oth dorsal and anal in contact with or very narrowly sejiarated from the caudal. Pectoral nearly half length of head, the spine very feebly serrated on the outer border and jj' the length of the fin.

Degen. LXXIV. — Note on a New Zealand Amphipod helonginrj to the Genus Seba. By CnAHLES CiiiLTON, M.A., D.Sc, F.L.S., Professor of Biology, Canterbury College, New Zealand. [The subjoined communication was sent to me by Prof. Chilton for publication. ISince receiving it I have carefully compared my female specimens and jMons. Chevreux^s descrip-tions and figures with i\\o?.coi S.Saundersii'm the 'Challenger' lleport. As regards the former, 1 can find no differences of any value, and 1 agree with Pr^f. Chilton that those given by Jilons. Chevreux cannot be relied on *. 1 have therefore come to the following conclusions: — * There is, however, a ninrked difl'erciice in the niniidibtilar pnljis: in S. Sau7iderfii (and in ^. antantica) the third joint is much lonj^er tlian the first, while in S. annntd it is said to be 8ht)rter. As the la^t-namcd species was taken ic the Ciulf of Ciascony, it is probably di-tiuct.
