 Abt. Systematik. Suppl. 9, Hft. 1, 1907, p. 86. 



Plymouth. One specimen was obtained amongst trawled 

 material from the Rame-Eddystone Ground. 



The specimen is in three pieces, but no portion seems to be missing. 

 Its total length would be about 260 mm. There are 21 setigerous 

 segments and three pre-anal achetous segments. The anal fmmel 

 resembles Ar^^ddsson"s figure. The anterior border of the head has 

 not a broad, hemispherical outline, but is produced into a slight 

 but distinct blunt projecting process. This is not the Niconiache 

 maculata Arwidsson, which is the only British Niconiache recorded 

 in recent pubHcations by Mcintosh and Southern.
