erat 
the inner ramus of the right uropod, but falls a little short 
of that on the left side, this want of symmetry corresponding 
with that observed in the antennal scales. The outer ramus 
of the uropods is considerably longer than the inner, and has 
a well-marked lateral tooth. 
The total length may be estimated at 144 mm. if the inflexed 
part of the pleon were straightened out, the carapace with 
rostrum measuring 74 mm. in length by 39 mm. in greatest 
height. 
Locality—Under date August 19th, 1903, Dr. Gilchrist 
writes concerning this specimen, “ A deep sea prawn of a bright 
red colour. The original colour will probably be retained 
when you get it, as we have had it for over a fortnight without 
any change being observed. Procured in a fine tow net attached 
to beam trawl. Loc. Cape Point, N. 70° E., 40 miles. Depth, 
about 800 fathoms. Bottom, green mud.” After a year the 
fine red colouring remains, as depicted in Faxon’s plate by 
Westergren.

Consistency requires that this family should take the name 
Thysanopodidae from the premier genus Thysanofoda, Milne- 
Edwards, 1830 (Ann. Sci. Nat., Vol. 19).
