1 In the Zweif. Kais. Mux. Wien, V, p. 320, these authors give affinis as a probable 
variety of polychceta, but the two names are evidently referable to one and the same 
species. Schiner's statement in his Fauna Auetriaca, Vol. I, p. 403, that in affinis the 
frontal bristles are in a single row, while in polychceta they are in two rows, or irreg- 
ularly arranged, does not hold true in all the specimens; in one of those from 
Germany, referred to above, they are in a single row on one side of the front, but are 
irregularly arranged on the opposite side.
