Sue PYCNOGONIDA OF THE WESTERN NORTH ATLANTIC 
AND THE CARIBBEAN 
By Jory W. Heparreru 
Since Wilson’s ‘‘Report on the Pycnogonida of New England and 
Adjacent Waters” (1880) and his ‘‘Report on the Pycnogonida of the 
Blake” (1881), there has been no comprehensive treatment of the 
pycnogonids of the eastern United States and the deeper waters of 
the western Atlantic.' The extensive dredging operations of the 
steamer Albatross from 1883 to 1887 off the eastern United States 
brought up a large assortment of pyenogonids, several of them unde- 
scribed at the time. These were laid aside by the late Prof. A. E. 
Verrill, who planned a report on them. This did not materialize, 
however, except for a preliminary list (1885) on the first season’s 
work of the Albatross. 
Taxonomic work on the group from western Atlantic waters since 
that time is represented by two short papers (Verrill, 1900; Cole, 
1904b) on species from Bermuda, and one (Cole, 1906a) on a Bahama 
species. More recently, Giltay (1934d) described another species from 
Bermuda, but his plan to work up the United States National Museum 
collections from the Caribbean region was cut short by his untimely 
death. The pycnogonids of the Woods Hole region are well known 
1 Edmund B. Wilson, 1856-1939, the great morphologist, embryologist, and teacher, noted for his treatise 
“The Cell in Development and Inheritance.’”’ His early work with the Pycnogonida has been recognized 
by Schimkewitsch (1887, 1889), who dedicated Achelia wilsoni, a species from southern Argentina and Chile, 
to him. See H. J. Muller: “Edmund B. Wilson—An Appreciation,’’ Amer. Nat., vol. 77, pp. 5-37, 142-172, 
ibe Louis Giltay, 1903-1937, ichthyologist and arachnologist. For an obituary, photograph, and bib-
