MARINE AMPHIPODA IN MICRONESIA — BARNARD 



513 



Relationship: This species differs from the other two of the genus, 

 P. suluensis (Dana) and P. albidus (Dana) by the lack of dorsal 

 segmental teeth. The mandibular palp is barely distinct from that 

 of the genus Maera but article 1 is definitely elongated so that this 

 species, therefore, is relegated to Parelasmopiis. 



Distribution: Ifaluk Atoll, Caroline Islands.
