298 MR. A. O. WALKER ON THE 
forwards and terminated by a row of divergent sete; the Ist 
joint about half the length of either of the others. The 6-jointed 
flagellum about equals the peduncle. The lower antenne are 
much stronger than the upper; the peduncle 2-jointed; the 
flagellum 4-jointed, hardly as long as the peduncle. 
First pair of legs but little shorter than the others, the 1st 
and 2nd joints subequal and narrow, shorter than the 5th 
(propodos); the 3rd and 4th short, the latter produced and ter- 
minated by 4 or 5 spines; the 5th long-oval; the dactylus long, 
with a secondary tooth near the base. 
Ambulatory legs as in Pleurogonium. 
Uropoda placed near the base of the caudal segment, the 
peduncle about half the length of the subequal rami, with two 
long divergent sete at the distal end; rami about as long as the 
lateral processes, and similarly armed with retroflexed spines or 
Sete. 
Length 1:2 mm. 
I am much indebted to Mr. Andrew Scott for dissecting and 
figuring this minute and curious Munnid. I have no hesitation 
in saying that without his kind assistance I should have been 
unabie to describe it.
