broad. Because of the small size and the sexual 
immaturity of these specimens they possibly 
could be interpreted as young M. oculata. 
However, inasmuch as the cleft of the telson 
in specimens of M. oculata of similar size had 
the adult configuration, the present specimens 
were considered to be young of Af. relicta. 
Like M, oculata, Af. relicta is circumpolar 
in distribution and occurs not only in brackish 
and fresh water lying near the present Arctic 
Ocean but also as far south as the lakes left 
by the continental ice sheets, such as the 
Great Lakes of North America. Dr. Mohr, in 
a personal communication, has described the 
pond where he collected these specimens at 
Point Barrow: 
There extends northeast from Pt. Barrow base 
for about seven miles a peninsula . . . called 
Nuwuk. On the tip there are several shallow 
pools and a larger one roughly a block long and 
at least 17 feet deep near the center. . . . Nuwuk 
pond is possibly a hundred yards from the pres- 
ent seashore. Between the main pond and the 
sea is a smaller pond which would about halve 
that distance, and very clear and apparently 
quite recent channels connect the smaller to 
the main pond. ... I had the strong impression 
that Nuwuk Pond was of recent separation from 
the sea. I think [that the geologists of the party 
were inclined to agree with this]. 
This species has been reported previously from 
Arctic Alaska.

SPECIMENS examined: Arctic Research Lab- 
oratory: No. 532, beach. Point Barrow, Alas- 
ka, Sept. 28, 1950; Wiggins, collector. One 
specimen.

No.?, plankton tow near shore, July 13, 
1950; MacGinitie, collector. One specimen, 
broken (identification not certain). 
King Crab Investigation: No. €-109, stomach 
of Gadus macrocephalus, Point Moller, Alaska, 
20-23 fathoms, June 5, 1941. One mature 
male 32 mm. long. 
DISCUSSION: These records add nothing to 
the known range, as Point Barrow is the type 
locality and the species have been previously 
reported from the Bering Sea region.

western record, that of Ortmann for the type 
specimens from Kodiak Island, Alaska.
