232 Dr. W. T. Caiman on XXXV. — Notes on a small Collection of Plankton from New Zealand. — I. The collection was made by Miss Margaret Benson, D.Sc, in the Bay of Islands, New Zealand, about 35° S., 174° E. It is much to be desired that other travellers should follow this excellent example ; the necessary outfit is small and inexpensive, the work is easy and clean. Three hauls were made under different conditions, but all were at the surface and between high water and half-tide. As might be expected, the bulk of the catch in each case consisted of Medusae, Copepoda, and other small Crustacea. I. CRUSTACEA (excluding Copepoda). By W. T. Calman, D.Sc, British Museum. (a) Cladocera. Penilia schmackeri, Ricbard, Ann. Sci. Nat., Zool. (7) xviii. p. 344, pi. XV. figs. 5, 7, 11, 15, pi. xvi. fig. 8 (1895). Penilia padjica, Kramer, Trans. Is'ew Zealand Inst, xxvii. p. 222, pi. xxiii. figs. 1-5 (1895). Penilia schmackeri, Hansen, Cladoceren u. Cirripedien, Plankton-Exp. p. 4, pi. i, figs. 1-1 b (1899) ; Sudler, Proc. Boston Soc. Nat. Hist. xxix. pp. 109-131, 3 pis. (1899) ; Richard, Bull. Mus. Oceanogr. Monaco, no. 52, p. 9 (1905). The numerous specimens referred to this species (hauls 1 A, 1 B, and 1 c), which are all females, agree closely with the figures and descriptions of Richard and Hansen quoted above, and confirm the suggestion of Hansen that the F. imcijica of Kramer, from Hauraki Gulf and Port Jackson, is identical with Richard's species. The known distribution of the species includes Hong Kong, Vera Cruz (Gulf of Mexico), Beaufort (North Carolina), the Gulf of Guinea, and the Mediterranean.
