Parker et al (1964) measured several environmental variables and 
showed that the pH and salinity were nearly constant in all subareas 
(7.8-8.1 and 31-32 % 0 ). Eh varied considerably spatially and tem- 
porally, especially in the inner harbor subarea where reducing condi- 
tions often were present. Light penetration was also minimal in the 
turbid inner harbor waters. The outer harbor subarea showed the 
least fluctuation in environmental variables. 
ACKNOWLEDGMENTS 
This study was made in cooperation with the Systematics-Ecology 
Program of the Marine Biological Laboratory (MBL), Woods Hole, 
Massachusetts. I am grateful to Dr. Carriker and Dr. Parker of the 
MBL for all the assistance they have given me. Thanks also to D. 
Boucher, T. Levinson, L. Overby, and M. C. Taylor for their labora- 
tory assistance, and Drs. Ellison, Gibson, and Smith who reviewed 
the manuscript and offered helpful suggestions. The study was sup- 
ported in part by the Ford Foundation. 
METHODS 
Samples were collected by means of a small coring tube If" in diam- 
eter or by a small (0.1 sq m) Van Veen sampler. In each case, about 
10 ml of surficial sediment was removed and placed in a 10 percent 
solution of buffered formalin. 
About 0.1 g of Rose Bengal stain (see Walton, 1952) was added to 
each sample a day prior to examination. After staining, the samples 
were washed over a 63 ju, sieve, dried, and floated, using bromoform 
with a specific gravity of 2.4. All material which did not float was 
examined for Foraminifera to insure complete recovery. In most 
cases very few specimens were found in the sink. For a discussion of 
the method, see Gibson and Walker (1967). 
After the preparation outlined above, the samples were re-wet with 
water to which a few drops of ethylene glycol, a wetting agent, was 
added to surpress floatation of the specimens. The samples were then 
picked and/or counted to determine the number of individuals in the 
various species. 
DISTRIBUTION 
The initial collecting date was in July 1964. These 1964 stations 
are numbered 95 through 119. The area was sampled a second time
