and propodus, which are of about equal length. Merus with 1 or 2 setae near 
each other on the lower distal margin. Carpus around the distal margin with 
a circle of 8 broad setae. 
Pleopods normal. 
The wropods consist of 5—7 joints, of which the last is the smallest and 
sometimes very minute. The longest female specimen, 4.1 mm, had 6 joints, 
the last one short. The longest male specimen, 3.5 mm, had 7 joints in the

uropods, the last joint minute. One small female, 2.; mm in length, had 5 
joints, of which the last joint was minute. One small male specimen, about 
3 mm in length, had 6 joints, the last joint short. Still smaller male individ- 
uals, 2—2.5 mm, have 5—6 joints in the uropods. In individuals with 5 
joints the last one was the shortest, but it was not very much shorter than 
the penultimate joint. This exemplifies the fact already pointed out by VAN- 
HOFFEN (1914, in Yanats litoralis and gracilis), that the number of joints in 
the uropods increases with age, and that the size of the terminal joint varies.
