This species was very rare at Provincetown, but we found it in great

 mark.

 Amphitrite brunnea Verrill. — Check-list. 



Professor Verrill regards A. Johnstoni Malmgren as a synonym of 

 T. hrunnea Stimpson. Stimpson's description, however, is very im- 

 perfect. We found two specimens which agree in most particulars, 

 though not in all, with Malmgren's figures of A. Johnstoni. They have 

 twenty-four segments with capillary setse. A very fine large species, 

 dredged in deep water by the Fish Commission, and regarded at first 

 by Professor Verrill as A. brnnnea, has twenty-five segments with capil- 

 lary setsB. Our specimens of A. brunnea were found under stones, at 

 low-water. 



mCOLEA Malmgren. 



Nicolea viredis n. sp. 



(Pl. VI, Figs. 73,74.) 



The frontal membrane is very large ; the tentacles numerous and 

 long, some of them as long as the body.
