1) According to M'Intosh' description the proboscis of N. atlantica should 

 have in group V. two narrow horny ridges, and behind one a small poste- 

 rior tooth (in extrusion), and in VI. the tooth should be absent; however as 

 we know no species of Nereis, having transverse teeth in group V, 1 suppose 

 an error must have crept into this description, due to the difficulty of recog- 

 nizing the exact arrangement of the paragnathi, when the proboscis is not in 

 state of extrusion. Therefore I believe that in N. atlantica the two horny 

 ridges are situated in group VI. and the small tooth in V, as in other species 

 of Perinereis; should this not be the case, the species could not at all belong 

 to Kinberg's Perinereis, as supposed by M'Intosh.
