Eleven species of Pycnogonida are recorded from depths between 230 and 3663 metres in the northern Atlantic. Of these, Nymphon inerme Fage, 1956, hitherto known from a single female specimen collected in the Kermadec Trench in the Pacific, is redescribed, whereas Ascorhynchus pudicum Stock, 1970 is recorded for the second time from a station near the type locality.
