ing high up, and separated as it were from the upper lobe, which 

 is not crenated but plicated on both upper and lower margins 

 with numerous small plaits running down the ventral side of the 

 segment. Tentacle, antennae, and palpi indistinctly articulated, 

 rather short, and ringed at intervals with dark bands. Tentacular 

 cirri not equal in length to the transverse diameter of the buccal 

 segment. The branchife commence about the seventh segment ; 

 pectinations few throughout, about five in number. Dorsal cirri 

 stout but not long. Ventral cirri short and conical. Anal cirri 

 ringed with dark rings. 



Peet : — Simple setae numerous, lanceolate, very long and very 

 finely pointed. Pectinate setae few in number ; pectinations or 

 teeth numerous, and, as it were, double, one row beneath an- 

 other, the outermost tooth on each side being the longest and 

 strongest. Compound setae shorter than the simple setae ; fal- 

 ciform appendage bidentate ; one tooth sharp and prominent, a 

 little below the apex, the other blunt and near the lower part. 

 Spines or aciculae appear to be three in number ; two dark-coloured, 

 stout, straight, blunt-pointed, and rather long ; a third shorter, 

 lighter-coloured, and obtuse at extremity. One uncinus only, of 

 considerable length, curved, and forcipate at the apex.

Body stout, tapering towards the lower extremity, and consist- 

 ing of about 140 articulations. Buccal segment broad, nearly 

 equal in length to the transverse diameter of the first three seg- 

 ments of the body. Whole body of a metallic lustre. Tentacle, an- 

 tennae, and palpi rather short, moniliform. Tentacle and antennae 

 of nearly equal length. Tentacular cirri articulated, equal in 

 length to the transverse diameter of the buccal segment. Ventral 

 margin of the buccal segment not crenate. The branchiae com- 

 mence on the fifth segment, quickly arrive at the maximum num- 

 ber of pectinations, soon decrease in size, but continue to be pre- 

 sent till near the extremity. Dorsal cirri short, stout, articulated. 

 Ventral cirri short and stout. 



Feet : — Setae unusually long. Simple setae long and very sharp- 

 pointed. Pectinate setae with rather numerous pectinations, the 

 outside tooth prolonged and slightly curved inwards. The com- 

 pound setae have the falciform appendage strongly bidentate ; one 

 tooth (as usual) under the apex, the other on the lower portion.
