DISCOVERY REPORTS 



The ventral bristles (Fig. 9, c) are relatively broader than those figured by Augener, 

 and the gap between the two terminal teeth less wide. Moreover, the uppermost ventral 

 bristles are unidentate and the rest bidentate, a condition apparently exactly the reverse 

 of that described by Augener, who records that the lowest ventral bristles somethnes 

 lacked the second tooth. 



It is not possible to attribute this fragment to a species with any certainty.

Remarks. These specimens correspond so closely to Fauvel 's description that there 

 is very httle I can add. The larger specimens have about 40 chaetigers and 16 pairs of 

 elytrophores : they measure about 37 mm. by 2 mm. without the feet and 6 mm. 

 including the feet. All the elytra are lost. In most of the specimens the huge cirro- 

 phores are larger anteriorly than behind. Up to about the i6th chaetiger they are 

 longer than the feet; further back they are of about the same length. Up to the nth 

 to 13th feet the cirrophores are transparent; over the rest of the body they are filled 

 with a pale brown, or grey, granular inclusion. On staining this shows itself to be 

 glandular tissue with a granular secretion. The elytra are all lost. The notopodial 

 aciculum is clearly visible in all the feet.
