 brown bands on posterior margin of body segments, the bands on 

 the tirst 3 abdominal segments being especially 1)road ; the telson,

First antennae about •''/4 as long as body ; peduncle rather long 

 but shorter than flagellum, tirst joint moderately stout, cylindrical, 

 second joint slightly longer than hrst, third joint rather short and 

 slender; flagellum made up of 22 or more segments, the first of 

 which is scarcely to be distinguished from terminal joint of ])ed- 

 uncle ; secondary flagellum made up of 5 segments. Second an- 

 tennae shorter than first, flagellum rather short ; gland cone 

 rather long and slender, extending beyond distal end of third 

 segment which is about twice as long as broad, fourth segment 

 slightly longer than fifth, rather long and slender ; flagellum made 

 up of about 9 joints, al^out equal in length to last joint of peduncle. 



Mandibles with all parts well developed ; palp 3-jointed, first joint 

 moderately long, broader 'at apex and bearing sharp spinelike pro- 

 cess at inner distal corner, second joint longest, tapering slightly 

 toward distal end and bearing 4 long setae on inner margin ; third 

 joint about ^/2 as long as second with slender rounded apex which 

 bears several long setae and is also provided with 2 setae on inner 

 margin and 1 on outer ; principal cutting edge divided into 2 rounded 

 teeth ; secondary cutting edge broad, made up of 4 equal teeth ; 

 7 plumose spines on spine row ; molar tubercle moderate. First 

 maxillae with 2-jointed palp, second joint longer than proximal joint 

 and broader at apex which is provided with numerous spines ; outer 

 plate large, with 6 or 7 branched and pectinate spines on oblique 

 distal margin ; inner plate broad, triangular, with inner margin provid- 

 ed with row of long plumose spines. Second maxillae of usual form, 

 plates oval, subequal ; outer plate with apex provided with setae ; inner 

 plate with setae on inner margin as well as apex. Maxillipeds 

 with plates well developed ; inner plate with apex truncate and 

 outer and inner angles prolonged to form toothlike processes, apical
