Monro, C. C. A. (1928). Polychaeta of the Families Polynoidae and Acœtidae from the Vicinity of the Panama Canal, collected by Dr. C. Crossland and Dr. Th. Mortensen. Journal of the Linnean Society of London, Zoology. 36(248): 553-576.
The Polychaeta collected by Dr. Cyril Crossland on the cruise of the S.Y. 'St. George' in 1923-1924 were presented by him and by the Scientific Expeditionary Research Association to the British Museum. Except for two species procured on the Atlantic side of the Isthmus of Panama, the collection was obtained in the vicinity of the Pacific mouth of the Panama Canal and the Galapagos Islands. Furthermore, Dr. Th. Mortensen, of Copenhagen, has very kindly entrusted me with the determination of a collection of Polychaeta obtained by him in his Pacific Expedition of 1914-1916, and the two collections are dealt with together.
