RECORDS OF COLLECTION 
Albatross station 2307, Oct. 21, 1884, lat. 35°42’00’’ N., long. 74°54'30"" W., 
43 fathoms, 5 specimens. 
St. Joseph Island, Tex., from sargassum cast on beach, April 16, 1946, J. W. 
Hedgpeth coll., 12 specimens (including ovigerous males). 
The females of the Texas specimens are almost glabrous; the males 
are slightly spinose. Although the lateral processes of the Albatross 
specimens (used in preparing the figure) are more widely separated 
than seems characteristic for this species, they are otherwise insepara- 
ble from A. petiolatus. 
Distribution.—Anoplodactylus petiolatus is widely distributed along 
the European coast from Norway (about lat. 69° N.) to the Mediter- 
ranean and in the Sargasso Sea; in Santos Bay, Brazil, and the Beagle 
Channel (Tierra del Fuego) and on the coast of southern Chile. 
These southern records may not be of the same species. As Marcus 
(1940b, pp. 41-42) has shown, the widely published record of Alaska 
for this species is based on Norman’s (1908, p. 202) error in misinter- 
preting a comparative table of differences between A. petiolatus and 
A. erectus Cole in Cole’s (1904a) paper on California and Alaskan 
pycnogonids. It has not yet been collected in North Pacific waters.
