Child, C. Allan. Pycnogonida of the Western Pacific Islands, XI: Collections from the Aleutians and Other Bering Sea Islands. Alaska. Smithsonian Contributions to Zoology, number 569,30 pages, 10 figures, 1995.—This report treats 35 pycnogonid species from the Bering Sea and the northwestern Pacific with specimens from several island groups located there; the Commander Islands, Aleutian Islands, Pribilof Islands, and one lot from St. Lawrence Island. Six new species are described, illustrated, and compared with their nearest relatives: Eurycyde arctica, Eurycyde depressa, Eurycyde muricata, Pycnogonum stylidium, Nymphon hirsutum, and Colossendeis dalli. Four additional species inadequately described by W.H. Hilton (1942) are redescribed fully and illustrated as if new: Achelia megova, Achelia ovosetosa, Pallenopsis (Bathypallenopsis) pacifica, and Colossendeis microsetosa. New distribution data and a diagnosis are given for the other 25 species, and new morphological information is included for each species where applicable. Several specimens are identified only to Nymphon or Pycnogonum for lack of adults or recognizable specimens. OFFICIAL PUBLICATION DATE is handstamped in a limited number of initial copies and is recorded in the Institution's annual report, Smithsonian Year.
