These collections were made from April to October 1924. One or two species were obtained at Madeira, a number at Colón, on the Atlantic side of the Panama Canal, but the great majority were collected in the Panama Region and the Galapagos Islands. The Panama Region for our purposes comprises Balboa Docks and Panama, Taboga and Perlas Islands in the Gulf of Panama, Coiba and Jicaron to the north, and Gorgona to the south. An account of the geography and marine ecology of this region and of the Galapagos Islands is given by Crossland in his "The Expedition to the South Pacific of the S.Y. 'St. George'. Marine Ecology and Coral Formations in the Panama Region, the Galapagos and the Marquesas Islands, and the Atoll of Napuka" (Trans. R. Soc. Edinburgh, vol. lv. pt. 2, no. 23, pp. 531-554, 1 pl. and 11 text-figs., 1927). In this paper he points out that the physical conditions in the Panama and the Galapagos are entirely different.
I have decided to postpone the consideration of how far this difference is reflected in the Polychaete faunas of the two regions until I shall have completed the determination of the second half of Crossland's collection, namely, the Polychaeta Sedentaria. This question, geographical distribution, and the problem of the isthmian/division of the faunas can then be considered in the light of my knowledge of the entire collection.
