38 | ANNUAL REPORT OF THE 
REPORT ON THE COELENTERATES. 
By Henry B. BIcGELow. 
The most important accession received during the past year is 
the duplicate set of Medusae and hydroids collected by the Gram- 
pus during the summer of 1912. A series of the genus Stomolophus 
from San Diego, California, presented by Dr. C. A. Kofoid, may 
also be mentioned. 
During October, the stony corals were rearranged, with the 
expert assistance of Prof. L. E. Griffin, to whom thanks are due 
for his voluntary labors. Specimens have been loaned him for 
study. 
The winter was spent on the report on the plankton and ocean- 
ography of the GRAMPUS cruise of 1913, of which a summary was 
given in my last report. Oceanographic stations were occupied 
in Massachusetts Bay at irregular intervals on the steamer BLUE 
Wine, through the courtesy of the United States Bureau of 
Fisheries. 
From July 15 to August 29, I was in charge of the U.S. Fisheries 
Schooner GRAMPUS on an oceanographic survey of the coastal 
waters between Marthas Vineyard and Halifax, accompanied, as 
in previous years, by Mr. W. W. Welsh as assistant. As in the 
past, the main efforts were directed to obtaining serial tempera- 
tures, serial water samples, measurements of ocean currents, and 
to the collection of plankton with qualitative and quantitative 
nets. The first field was George’s Bank, across which two sections 
were drawn, one at the west, one at the eastern end, extending 
from the basin of the Gulf of Maine on the north to the continen- 
tal slope on the south. We then ran a section across the eastern 
channel, between George’s and Brown’s Banks, interesting oceano- 
graphically, because it is the sole connection between the basin 
of the Gulf below the 100 fathom level on the one hand, and the 
deeps of the Atlantic on the other; and then via Brown’s Bank, 
the Northern channel, and the coast bank to Shelburne, Nova 
Scotia. Off that port, on July 27, ocean currents were measured
