segment of the peduncle; the eye extends to the second segment, which, 
as well as the third, is very short. The antennal peduncle falls short of 
the middle of the scale; scale short and broad, subequal in length to the 
rostrum. 
The maxillipeds exceed the antennal scale a little. The palm of the 
first pair of feet overlaps the last segment of the maxillipeds. The last 
three pairs of feet are rather stout, and the last pair exceeds the antennal 
peduncle a little. 
Abdomen conspicuously punctate. 
Male.—The rostrum is horizontal or deflexed, and very slender, and 
the spines are small and appressed. Peduncles of antennule more 
elongate than in the @, eyes not reaching end of first segment, basal 
scale extending to middle of second segment. 
Dimensions. — Ovigerous 2: length (approximate) 37.5 mm., length 
of carapace and rostrum 13 mm., of rostrum 5.3 mm.
