middle; pecten reaching one-third, of long spines, followed by 

 six tufts along the posterior margin, being three pairs dislo-

 scarcely dislocated. Tracheae slender, winding around in the 

 tube. Lateral comb of the eighth segment of many spines in a

Clasp-filament slenderly snout-shaped, the spine long and 

 slender, scarcely widened. Outer division of lobe of side- 

 piece with a slender inner arm, from which arises a long and a 

 short filament, the long one flattened and hooked at the tip, 

 the short one blade-like ; middle filament broadly blade-shaped, 

 long; three filaments on the outer aspect of apex contiguous, 

 curved, a little flattened. Inner division of lobe of side-piece 

 with the outer arm short, the inner very short, not widely 

 separated, each bearing a large filament with expanded pointed 

 tip. Second uncal plate with the tip widely expanded, mem- 

 branous, sharply serrate all along the edge, with a point at 

 either end ; a long spine below the middle of the stem. Articu- 

 lated plate small, triangular, darkly chitinized. Basal hooks 

 small, broad, not recurved. Basal appendages large, ovate, 

 nearly twice as long as broad, with many rather long setse.
