500 PROFESSOR CHARLES CHILTON ON THE 
This species had been recorded from South Africa by Mr Srepprine under the name 
of Atylordes assimilis, from a specimen found on the screw of the Challenger off Cape 
Agulhas. Mr Svespine’s figure of the telson shows some approach to that of the 
Saldanha Bay specimens, but each lobe bears only two acute teeth. 
Genus Dsersoa Chevreux, 1906. 
Dyerboa furcipes Chevreux. 
Djerboa furcipes Chevreux, 19068, p. 74, figs. 42-44. 
South Orkneys, Scotia Bay, Station 325; 10 fathoms. (No date.) A few 
specimens, the largest 15 mm. 
South Orkneys, Scotia Bay, Station 325; 15 fathoms. April 1903. Six 
specimens, the largest 18 mm. long. 
These specimens agree well with the description and figures given by CHEVREUX. 
They bear a very close and striking resemblance to Leptamphopus nove-zealandie, 
and it is very difficult to distinguish the two species without dissecting off the 
telson, which is deeply cleft in Djerboa furcipes but undivided in Leptamphopus 
nove-zealandix ; in the first species, however, the integument is marked by a number 
of short marks arranged more or less in parallel lines, and in doubtful cases this helps as 
a guide to their identification.

South Orkneys, Station 325; from stomach of Weddell seal. 4th January 1904. 
One male, 45 mm. long. 
South Orkneys, Station 325; dredge, 9-10 fathoms. 17th August 1903. One 
female, 22 mm. long; June 1903, one female, 20 mm. 
In the large specimen all the segments of the perzeon and pleon are rounded 
dorsally ; the pleon is slightly compressed but not carinate ; teeth are present on the 
first and second segments of the urus as described; the third uropods are missing. 
The female specimens also show no carination on the perzeon or pleon, and have the 
third uropods of moderate size only. The upper antenne are considerably longer than 
half the body ; the second joint of peduncle is as long as the first, and the flagellum is 
considerably longer than the peduncle. In the lower antennz the flagellum is longer 
than the last joint of the peduncle. Except for the absence of carination, the specimens 
agree closely with PrEFFER’s description. 
This fine species is now known from South Georgia, South Orkneys, Port Charcot, 
Booth Wandel and Hovgaard Islands.
