setac. The mouth parts are normal; the mandible and maxillule were lost in the 
first dissection but are shown in the figure of the oral region. In the seta formula 
for the legs the distribution around the terminal segments is not shown, but the 
figures indicate the total number of setae and spines respectively on these seg- 
monts :

The fifth leg consists of a single segment, half as long again as wide, with its inner 
distal corner produced into a pointed process and armed terminally with one long, 
bladed spine and a shorter seta, 
Sun-ramiLy LICHOMOLGINAE Gurney. 
This group contains those genera in which the fourth endopod is reduced to 
two or fewer segments, sometimes being absent. 
Genus PsrupantTHessius Clans. 
Claus, 1889, p. 344; Sars, 1917, p. 166. 
The synonymy of this genus has been diseussed by Gurney (1927, p. 463) and 
by Monod and Dollfns (1932, p. 139). It need only be added that P. fucicolus T. 
Scott (1912) should be transferred to Gurney’s genus Kelleria, which he estab- 
lished (1927, p. 470) for ‘‘certain species in which the endopod of leg 4 is one- 
jointed, but with an inner seta and a noteh in the posilion of the joint m Licho- 
molgus, and with a freely movable 5th leg’’ (op. cit., p. 463). The following species 
remain in this genus: liber and thorelle (Brady and Robertson) 1875; gracilis 
Claus 1889; swwvagei Canu 1891; concinnus Thompson and Scott 1903; obscwrus 
and weberi A. Scott 1909; assimils Sars 1917; dubius Sars 1918; mucronatus 
Gurney 1927; nemertophilus Gallien 1985. 
The species found here ean be identified with none of these and so must con- 
stitute a new species.
