These specimens agree exactly with Walker’s description and figures 
except that the palm of the 2nd gnathopod in the male has two little 
denticles near the finger-hinge. These are not mentioned by Walker, 
but are easily overlooked owing to the denseness of the fringes of 
plumose setae. The finger of the Ist gnathopod in both sexes is 
serrate on the inner margin and the palm in the male is minutely 
crenulate. 
Posterior margins of peraeon and pleon segments sparsely setose, 
in the ¢ the humps on the 7th peraeon and Ist-3rd pleon segments 
each bear a little median tuft of setae. Antero-lateral angles of 
peraeon segment 1, as well as those of the side-plate, acutely produced 
forwards. 
Hyes on the antero-lateral angles of the head. 
Length: & 6mm., 2 3 mm. 
Colour: Light brown, speckled with darker, often a dark spot on 
the 3rd and 4th side-plates and in the ¢ a medio-dorsal spot on 
6th peraeon segment, ? frequently with a pale oval dorsal patch 
extending over 3rd—6th peraeon segments, a dark transverse band 
between the eyes, which are bright red, sometimes the whole head dark.
