(With Plates 6 and 7). 
During his stay in Java Mr. Edward Jacobson collected 
from 1909 to 1911 a small number of terrestrial Amphi- 
poda which he has been good enough to hand over to me 
for identification. They all prove to belong to Orchestia 
parvispinosa, a species described from Java by Max Weber 
in 1892; Weber however had only female specimens and 
the male has remained unknown all these years. Mr. Ja- 
cobson’s. collection consists nearly all of females, as is usu- 
ally the case with collections of terrestrial Amphipoda, but 
fortunately it contains one male which, though apparently 
not fully mature, is sufficiently developed to give a general 
idea of its chief characteristics. I therefore give a brief 
description of its gnathopoda and add one or two items 
of additional information about the species and its relation- 
ship to allied species.
