DISCOVERY REPORTS 



Specific characters. A small species with a length of about lo mm. for 25 

 chaetigers. The present specimen measures 5 mm. by 2 mm. at the widest part for 21 

 chaetigers. There are two pairs of eyes, one ventral just in front of the 

 buccal lobes and one dorsal on the prostomium. The caruncle reaches 

 to the 6th chaetiger and the median tentacle is about one-third of its 

 length. The gills begin on the first chaetiger. In a normal segment 

 there are six branchial trunks on each side. Each trunk is very richly 

 branched and the tufts end in narrow unexpanded tips. The lower of 

 the two dorsal cirri lies between the 4th and 5th most dorsal branchial 

 trunks. The dorsal bristles consist of "ringent" bristles (Fig. i) and 

 smooth bifid bristles. The ventral bristles are smooth bifids of two 



sizes. 



Augener could not in his specimens see any serrations on the short 

 arm of the dorsal ringent bristles. In this specimen they are distinct. 

 Moreover, Augener gives the position of the lower dorsal cirrus as 

 between the 2nd and 3rd most dorsal branchia. I find it between the 

 4th and 5th, and this agrees with Augener 's figure.

Specific characters. There is no colour pattern, and except for the purple median 

 tentacle and dorsal cirri the body in spirit is more or less without colour. The gills 

 begin on the 5th chaetiger. The chaetae show no trace of serrations. Both in the dorsal 

 and ventral bundles they may be {a) perfectly smooth, {b) may exhibit a minute obso- 

 lescent spur. The ventral bristles are thinner than the dorsal, especially those in the 

 middle of the neuropod which are long, hair-like and extremely fine and also have an 

 incipient spur. 



The present specimen is a very young example of the species and measures 8 mm. 

 by 3 mm. at the widest part for 23 chaetigers. Up to the middle of the body dorsal 

 bristles of the two types already described are found, and in addition there are a few 

 bristles with small but complete spurs, but in the hinder region the dorsal bristles 

 appear all to be smooth. In the neuropod some of the ventral bristles of the first few 

 chaetigers have an obsolescent spur; otherwise they are smooth. The long, slender, 

 capillary type of ventral bristle is not present behind about the loth chaetiger.
