Description. The specimen measures 13 mm. by 2 mm. without the feet, and has 

 about 45 chaetigers and 18 pairs of elytrophores. There is no colour. 



The head (Fig. 7, a) is broader than long, somewhat rounded in shape, and with two 

 pairs of small eyes set rather far back and to the side. The insertion of the lateral ten- 

 tacles appears to be subterminal as in Halosydna, but of this I am not sure. The median 

 tentacle is about of the same length as the long and rather slender palps, and it is 

 longer than the lateral tentacles. The tentacular cirri are rather longer than the tentacles 

 and there is a long ventral cirrus on the first foot. The elytrophore of the first foot is a 

 cylindrical structure about half the length of the foot ; the remaining elytrophores are 

 conspicuous but not unusually prominent.
