This handsome species is the largest local member of the genus. 
It is usually about 10 cm. in extent, but mature specimens nearly 
half that size are known. 
Distribution —Primarily a Boreal-Arctic species, occurring as far 
north as latitude 82° (Stephensen), but it does not appear to be 
circumpolar, being unknown west of Baffin Bay or from eastern 
Siberia. But Hilton (1942a) mentions ‘“Nymphon gracillipes’’ 
from Albatross station 3540 (Bering Sea); although NV. gracilipes is 
considered a synonym of UN. strémi, this record is doubtful. Nymphon 
strémi is common in the New England region from 7 to 100 fathoms, 
but it has been dredged from over 500 fathoms. The Albatross 
records, stations 2666, 2667, and 2669, off South Carolina and Florida, 
are the southernmost localities for this species.

This small species was collected by A. H. Leim in Minas Basin, 
Nova Scotia, on September 8, 1920. There are four somewhat bat- 
tered specimens in the lot as lent to me by Dr. Alfreda B. Needler and 
Dr. A. G. Hunstman, of the Fisheries Research Board of Canada. 
No specimens seem to have been taken by the U. S. Fish Commission 
during its intensive investigations of the 70’s and 80’s. Because of 
its small size it may have been overlooked, but it is probably rare. 
Superficially Nymphon rubrum looks like a small grossipes, but the 
lateral processes are more widely separated, and the very long, straight 
spines on the proximal half of the propodus are not found in any forms 
of grossipes. As the name suggests, the creature is red in life. Ste- 
phensen considersrubrum very close to if not identical with N. brevirostre 
(Hodge), while Derjugin considers it, together with N. brevitarse, a 
variety of brevirostre. (See the discussion under Nymphon grossipes.) 
This species is often identified as N. gracile Leach, but neither N. 
rubrum nor N. brevirostre has the long fourth joint of the palpus which 
distinguishes gracile, a warm-water species found from the southern 
coast of England to Morocco and the Mediterranean. According to 
Sars’s figures, N. rubrum has tufts of setae at the distal ends of the 
femur and tibiae, but they are not present in the specimens from Nova 
Scotia. 
Distribution.—Norway to Belgium, British Isles to Plymouth, Nova 
Scotia.
