Figure 8 

 Halirages bungei Gurjanova, 1951, pp. 611-612, fig. 414. 



Female. — Head as long as first 2 body segments combined; rostrmn 

 very short, broad; lateral lobe obliquely trimcate; lower corner broadly 

 romiding; eye long, consisting of narrow black central area bordered 

 by colorless ocelli. Antennae subequal, but 1 perhaps slightly shorter. 

 Antenna 1 about as long as head and first 5 body segments combined ; 

 peduncle short, joints decreasmg consecutively in length; accessory 

 flagellum rudimentary (fig. 86) ; primary flagellum consisting of about 

 44 joints, every other one of which bears 2 sensory filaments on lower 

 distal end. Antenna 2 with fifth joint longer than fourth; flagellum 

 consisting of about 38 joints. 



Mandible with cutting-edge narrow, toothed; accessory plate narrow 

 with bifid apex; spine-row of 9 spines ; molar strong with well-developed 

 triturating surface and armed on upper edge with long slender teeth; 

 palp strong with second joint longest. Upper lip symmetrically 

 rounding. Maxilla 1, inner plate long, armed apically with 5 plumose 

 setae; outer plate armed with 11 serrate spine-teeth; palp 2-jointed, 

 rather broad, bluntly rounding apex armed with 14 serrate spine- 

 teeth and on outside with 6 subapical setae. Maxilla 2, inner plate 

 slightly longer, armed apically with spines, and on inner margin with 

 spines, 4 of which are longer than rest ; outer plate armed with apical 

 spines. Lower lip without inner lobes; mandibular processes rather 

 short, apically rounding. MaxUliped, second joint with several spines 

 on outer margin ; inner lobe rather long, reaching slightly beyond 

 middle of outer lobe, armed distally with curved plumose spines or 

 setae and 3 short spine-teeth, 2 innermost being separated from third 

 by slight sinus; outer plate reaching middle of second joint of palp, 

 bearing distally a closely set row of slender curved plumose spines, and 

 bearing on inner margin transparent lamella, from base of which arises 

 row of slightly curved serrate spine-teeth; palp rather short, stout, 

 third joint bearing group of spines near middle of outer margin and 

 spines and small rounding lobe distally; fourth joint rather slender, 

 slightly curved, bearing distally sharp nail and few setules. 



Gnathopods 1 and 2 alike in form and size, though 1 may possibly 

 be slightly longer; second joint scarcely expanded distally; fifth joint 

 not expanded, about % as long as sixth; sixth joint long, narrow, of 

 equal width throughout, bearing groups of spines on hind margin; 

 palm convex, very oblique, edged with narrow smooth transparent 

 lamella and merging into hind margm \\'ithout defining angle, but
