Telson a little longer than broad, slightly tapering, shallowly 
notched, apices rounded, each with 1 short stout spine. 
First antenna, Ist jomt longer and stouter than 2nd, with | strong 
spine on lower apex, 2nd joint with 4 spinules on upper margin 
and 2 spinules on upper apex, 3rd joint 3 length of 2nd, flagellum 
equal to 2nd and 3rd peduncular joimts together, 14-jointed. 
Second antenna, ultimate joint longer than penultimate, flagellum in 
¢ specimen very long, ca. 70-jointed. 
Upper and lower lips as figured by Sars for B. longimanus (Boeck ). 
Mandibles stout, cutting-edge thick, apex obtuse, nondentate, 
secondary cutting-edge represented by a stout spiniform process, 
apically bifid im left, obtuse in right, spime-row with 3 spines in left, 
5 in right, molar denticulate and setose, palp very stout, especially 2nd 
joint, which is scarcely curved but strongly angular on inner basal 
margin, 3rd joint not as long as 2nd, more slender than either Ist or 
2nd joints. 
First maxilla, inner plate with 3 apical setae and some very fine 
setules on inner margin, outer plate with 9 spines, some of them 
tending to be bifid, palp with 2nd joint widest in middle, inner distal 
margin with ca. 8 setae, 4 apical setae, outer distal margin with 
2 groups of 3 setae each. 
Second maxilla, inner plate broader than outer, both setose. 
Maxilliped, inner plate extending just beyond apex of 2nd joint 
(not of palp), inner apical angle with 1 spine, apical margin setose, 
outer plate not quite reaching end of 2nd joint of palp, inner margin 
with setae and strong spines, 2nd joint of palp not strongly expanded 
distally, 4th joint as long as 3rd. 
First gnathopod, 5th joimt produced into a lobe bearing several 
setae and 2 apical spines, 6th joint ovate, almost as long and as broad 
as 5th, palm convex, not very oblique, subequal to inferior margin, 
palmar spine present in one specimen only, finger just overlapping palm. 
Second gnathopod, 5th joint produced into a lobe but not so strongly 
as in Ist gnathopod, with numerous setae and 2 long apical spines, 6th 
joint shorter but a little broader than 5th, similar to that of Ist 
enathopod., 
First and second peraeopods, 4th and especially 5th joints rather 
strongly setose and spinose, 4th longer than 5th or 6th, which are 
subequal, finger in Ist peraeopod not quite as long as, in 2nd a little 
longer than, 6th, not strongly tapering, ending in a minute curved 
unguis. 
Third and fourth peraeopods, 2nd joint not expanded, oblong, 
tapering slightly, anterior margin in 3rd peraeopod slightly concave,
