ATLANTIC AND CARIBBEAN PYCNOGONIDA—HEDGPETH 185 
Distribution —Nymphon hirtipes has a more Arctic distribution than 
N. spinosissimum; it is common off northwestern Greenland and 
Baffin Land. It is also found in the Barents and Kara Seas. Stephen- 
sen (1933). suggests that it may live on the coral Hunephthya and 
presents a map showing the coincidence of these organisms with 
N. hirtipes off western Greenland. In the New England region it 
has been collected as far south as Massachusetts Bay. Stephensen 
(1943) has a map showing the Arctic distribution of this species (fig. 3) 
and another (fig. 4) of its occurrence around Greenland.

The description accompanying Wilson’s tentative identification of 
a specimen from Blake station 338 as Nymphon pallenoides Sars does 
not altogether agree with his figure of the tarsal joints. The tarsus is 
considerably longer than the same joint in N. hirtipes, but the long 
auxiliary claws are similar to those of N. spinosissimum. It is more 
slender in general appearance than either hirtipes or sprnosissimum 
and is smaller, about 3.5 cm. in extent. It is evident that Wilson’s 
specimen was WN. tenellum, since Sars’s N. pallenoides was later synony- 
mized by him under N. hirtum (Sars, 1891). 
Distribution.—Nymphon tenellum is not a common species. Accord- 
ing to Stephensen, Meinert’s records from west of Greenland are mis- 
identifications. It appears to be a North Atlantic deep-water species. 
GROUP B 
Four species in this group are characteristic members of the inverte- 
brate fauna of the New England region. Of particular interest are 
the southward extensions in range for Nymphon strémi and N. macrum 
(fig. 12). In addition to the localities indicated on the map, two speci- 
mens of Nymphon from south of Florida have been referred to macrum, 
although the tarsal joints and claws are heavier than in typical New 
England material.
