The station records cataloged in the following tables have been 
assembled from a number of sources, but particularly Sanderson 
Smith’s station lists for the North Atlantic (1889) and Townsend’s 
dredging records for the Albatross (1901). While it is realized that 
these lists are incomplete, all the published records from major 
reports on North Atlantic pycnogonids have been included, together 
with a few individual records of particular interest. Because of the 
predominantly Arctic character of the records, the inaccessibility of 
many of the papers, and the taxonomic vagaries indulged in by the 
Russians (Schimkewitsch, 1930, lumps Nymphon spinosissimum and 
hirtipes as N. spinosum, and more recent workers are suggesting such 
species as N. brevitarse and rubrum as varieties of grossipes), their 
reports have been omitted from this compilation. 
Records of the dredging work of the United States Fish Commission 
in New England waters before 1877 have not been included inasmuch 
as few of the collections were referred to station numbers on the 
original labels. The Speedwell records have been compiled from a 
reexamination of the original material, now in the Peabody Museum. 
Most of this material has previously been reported by Wilson (1880) 
but without reference to station numbers. It is not practical to 
indicate these stations on a small-scale chart; all the dredging 
stations of the Fish Commission up to 1886 will be found in the charts 
accompanying Sanderson Smith’s lists and should be readily accessible 
to American students. 
Hrrors are inevitable in a compilation of this type, and I can only 
hope that they are neither numerous nor serious. Several obvious 
errors in Norman’s review (1908) have been corrected to agree with 
the positions given by Sanderson Smith. Unfortunately, salinity 
data are unavailable for most of these stations, and so they have been 
omitted from the remainder. Reference to further information con- 
cerning temperature and salinity data of many expeditions in the 
North Atlantic is published in ‘International Aspects of Oceanog- 
raphy”? (National Academy of Sciences, 1937, pp. 7-19). 
Inasmuch as charts of station positions are included in the Nor- 
wegian North Atlantic, Ingolf, and Godthaab reports, and the distri- 
bution of the Arctic species seems to be well established, charts of the 
occurrence of pycnogonids in northern waters have not been pre- 
pared. The distribution of many of the Arctic species has been 
charted in Stephenson’s various papers. From Chart 2 of stations 
in the North Atlantic, it will be seen that there are vast areas from 
which we have no records of pyenogonids. There are no collections 
reported for the area between latitudes 10° to 40° N. and longitudes 
30° to 60° W., except the Challenger station 70, and the paucity of
