164 ORCHESTIA PARVISPINOSA, 
under which they were collected as given by Mr. Jacobson, 
is as follows: 
N°. 3140, Nongkodjadjar, 1200 m., above sea level, January 
1911, collected between plants; one female, 
7 mm. long. 
» 9141, ibid.; one female, 7 mm. long. 
» 3142, Gounoung Oungaran, 1000 m., December 1909, 
collected between plants; one female, 5 mm. long. 
„ 9148, ibid.; October 1910, collected between plants; 
one female, 5 mm. long. 
» 9144, Kali Tountang, about 100 m., October 1910, 
on the wet stones at the foot of a waterfall; 
one female, 7 mm. long. 
„ 8145, ibid.; one male, 7 mm. long. 
» 93146, Gounoung Gedeh, 1200 m., March 1911, col- 
lected between plants; one female, 7 mm. long. 
These specimens agree closely with the descriptions given 
by Max Weber and Stebbing and I have no doubt they 
belong to this species. I add the following notes to their 
descriptions. 
The inferior margins of the three segments of the pleon 
are slightly convex and bear no setae, the postero-lateral 
angle of the third is quadrate with slightly produced point 
and the hinder margin straight without serrations. The 
telson is triangular, narrowing to the end which bears a 
small notch with a spinule on the small rounded lobe on 
each side, each lateral margin bearing three other spinules 
of the same size at regular distances (Fig. 7). 
The antennae present no distinguishing characteristics. 
In the male the side-plate of the first gnathopod (Fig. 1) is 
slightly narrowed inferiorly with the angles rounded and there 
are three or four small setae on the inferior margin; the basos 
is somewhat narrowed proximally and does not widen at 
the distal end; the merus has a small rounded pellucid 
lobe on its hinder margin; the carpus is about the same
