It was found nocessarv to establish two new genera Streblospio 

 and Pakaxiotiiea ; of the species fourteen are believed to be new ; 

 one genus, Grubea, has not previously been reported from our 

 coast, although the species is probai)ly not new. The specimens 

 upon which the work is based are in the Museum of Union College, 

 and a nearly complete series has also been deposited in the New York 

 State Museum of Natural History.
