ANNELIDA CH^TOPODA OF THE VIRGINIAN 
COAST. 
By H, E. Webster. 
[Read before the Albany Institute, Oct. 15, 1878.] 
The Annelida catalogued and described in the follow- 
ing pages were collected in the summer months of 1874 
and 1876, by the zoological expeditions which, for some 
years past. Union College has sent out during the summer 
vacation. The locality was in Northampton Co., Virginia, 
(Easteru shore of Va.), between the main-land and the 
line of outside islands. Collecting on the eastern shore is 
in many respects unpleasant. The coast is monotonous ; 
there is very little variety of station, unless a change from 
soft black mud to softer blacker mud can be called variety. 
At low- water a great area is exposed, but from high-water 
mark to the edges of the channels it is always mud; and 
when the dredge is let down it comes up filled with the 
same variety of mud; of course under such circumstances 
the work itself can not be pleasant. However, there was 
abundence of life. At low water the flats were black with 
llyanassa ohsoleia Stimp., and two species of Gelasimus 
were present in numbers that defied computation ; oysters 
and blue-crabs were everywhere ; Amphitrite ornata was so 
common that in many places their extended tentacles 
almost touched each other ; Marphysa sanguinea appeared 
at every turn of the spade or haul of the dredge ; Nereis 
limbaia, Drilonereis longa, Cirratulas grandis^ Enoplobranchus 
sanguineus and other worms were present in the mud in 
great numbers; small annelids and molluscs abounded 
among the oysters. By far the greater part of our work 
was done with the spade at low-water. With the excep- 
tion of the Syllidae and some other small forms, nearly 
every species dredged was also found between tides. In 
a few places we found what our boatmen called " rocky
