circlet, flagellum barely as long as peduncle, ca. 21-jointed in ¢, ca. 17 
1m Os. 
Upper lip, distal margin strongly convex and setose. 
Lower lip, lobes short, broad, apically truncate, inner apical angle 
rounded, setose. 
Mandible, cutting-edge with 2 large and 5 small teeth, secondary 
cutting-edge in left 5-dentate, in right 3-dentate, spine-row with ca. 5 
spines. 
First maxilla, inner plate with 3 plumose setae, outer plate with 
9 spines. 
Second maxilla, inner plate shorter and narrower than outer, more 
pointed apically, with a large stout plumose seta at junction of inner 
and apical margins. 
Maxilliped, inner plate with 3 blunt teeth on truncate apex, outer 
plate not extending very much beyond inner plate (to middle of 2nd 
joint of palp), 4th joint of palp quite obsolete. 
First gnathopod in 4, 4th joint without apical process, 5th longer 
than 6th, with pellucid apical lobe, 6th not widening much distally, 
subchelate, inner apex with a rounded lobe, finger (excluding unguis) 
reaching to end of this lobe, with 2 setules on its inner apex, 
unguis unusually long, as long as finger; in 2, 2nd joint wider than 
in ¢, 5th without apical lobe, 6th simple, slightly tapering, finger and 
unguis asin ¢. 
Second gnathopod in @, 6th joint large, cordiform, hind margin 
short, bearing spines at equal distances apart, a very small defining 
tubercle, first portion of palm evenly convex and bearing spines as on 
the hind margin, the distal portion of palm concave, smooth, with a 
strong triangular tooth, spinuliferous at its apex, situate near the 
hinge, finger as long as palm, curved, inner margin slightly emarginate 
at the base; in 9, 2nd joint rather strongly expanded on anterior 
margin (half as long again as broad), 4th in the Dassen Island 
specimens apically produced downwards asa narrow subacute lobe, 5th 
broader proximally than distally and equal to 6th joint including its 
apical process, which is rounded and slightly curved upwards, finger 
and curved unguis very short. 
Second peraeopod, 7th joint sharply constricted, but its appearance 
is better described as having a tubercle in middle of inner margin, 
unguis long but not equal to 7th. 
Third peraeopod, 2nd joint expanded, rather broader than long, 
hind margin evenly convex, setuliferous, 7th slender, unguis not equal 
to 7th. 
Fourth peraeopod in ¢ very long, 2nd joint enormously expanded,
