Only a few examples of this species were taken, it being far less common 

 than in Virginia.

This species was not common. One very large adult male was taken swim- 

 ming on the surface. Its length was 22 mm ; sexual setse began on the 21st 

 segment ; existed on forty- two segments, followed by thirty- three with the ordi- 

 nary setae only. Other specimens were taken on sandy and shelly bottom, 

 10-15 ft. For further notes on this form, see Webster, 1. c, p. 220.

In some respects my specimens agree better with Grubea dolichopoda Mar- 

 enzeller (1. c, p. 26) than with G. tenuicirrata Clpd. This is especially 

 the case in the form of the setae and of the pharyngeal tooth. According 

 to Claparede's figure, the setae end in a single point, and with the magni- 

 fying power used by him this does seem to be the case ; in reality they are 

 bidentate, the teeth being very small, and requiring a high power to bring them 

 out distinctly. On only two specimens was the first dorsal cirrus much longer 

 than the second. 



The anal cirri, in the only case where they were seen, were as long as the 

 dorsal cirri, and somewhat swollen at base.
