and from the Philippine Islands agree very closely with those

As Paracalliope fluviatilis appears to be confined to fresh and 
brackish water near the coast, its wide distribution in India, 
Philippine Islands, and New Zealand will help to throw light 
on the changes in the land areas of these regions that must 
have occurred to account for its present distribution. In this 
connection it may be mentioned that Paracorophium excavatum 
(G. M. Thomson), another amphipod occurring in brackish and 
fresh waters of New Zealand, has recently been sent to me from 
brackish waters in Brisbane River, Queensland, Australia.
