oval. First maxillae with 2-jointed palp, of which the terminal joint 

 is club-shaped with sharp spines on apical margin ; outer plate rather 

 large with obliquely truncate apical margin provided with branched 

 spines ; inner plate very small, triangular, provided with setae on 

 inner margin. Second maxillae with outer plate longer than inner 

 and much broader apically than proximally, provided with setae 

 apically ; inner plate tapering, with rounded apex, which, with inner 

 margin, is provided with plumose spines. Maxillipeds with plates 

 w^ell developed and with 4-jointed palp ; inner plate extending about 

 as far as apex of tirst joint of palp, rounded and provided with 

 plumose spines and with apical odontoid spine ; outer plate large, 

 oval, extending beyond apex of second joint of palp ; inner margin 

 armed with odontoid spines which increase in length and become 

 slender distally ; palp with first joint triangular, short, second joint 

 cylindrical with spines near distal end of inner margin, third joint 

 short, broader distally, with setae on distal half of inner margin and 

 apex, fourth joint curved, conical, armed with clawlike spine apic- 

 ally and several setae on inner margin. 



In male, first gnathopods with triangular epimeron bearing setae 

 on ventral margin, about as high as greatest length ; second joint 

 rather long and slender with small rounded process at distal end 

 of anterior margin ; third joint short, more or less triangular ; fourth 

 joint moderately long, with long, rather slender process at distal 

 end of posterior margin, so that posterior margin, which is provided 

 with setae, is much longer than anterior, distal margin oblique, ar- 

 ticulation with wrist rather short ; wrist very long, as long as second 

 joint and much stouter, articulating with fourth joint liy proximal 

 part of posterior margin, distal portions of posterior and anterior 

 margins parallel, distal margin transverse, margins provided with 

 setae ; hand oval, stout, palm very oblique, slightly convex, posterior 

 margin very convex, separated from palm by prehensile spine, an- 

 terior margin moderately convex, hand broader than wrist but 

 shorter, slender setae on palm, posterior and anterior margins ; 

 finger moderately long, with serrated concave margin. 



Second gnathopods with epimeron rectangular, slightly higher 

 than long with ventral margin provided with long setae and slightly 

 indented by broad sinus ; second joint rather long with anterior 

 margin provided with setae ; third joint of usual form, about as long 

 as broad ; fourth joint rectangular, with posterior margin provided 

 with setae near distal end and longer than anterior, apex somewhat 

 oblique ; wrist triangular, articulating with almost entire anterior 

 margin of fourth segment, posterior margin provided with short
