Lumbrineris minuscula nom. nov. 



Lumbriconereis minuta Treadwell, Bull. U. S. Fish Comm., 1906, p. 1171, 

 figs. 57, 58 (nom. preoc. L. minuta Theel, 1S79). 



Three very poorly preserved anterior ends of a species that is much 

 like Tread well's L. minuta, but differ in several respects and especially 

 in the great prolongation of the limbate set*, which, coupled with the 

 fact that the specimens, and especially one male, are filled with genital 

 products, leads to the suspicion that they are an epitokous phase of 

 that species.
