with the others in the annotated list, and these records have been included in plotting 
the distribution charts. 
During the summers of 1906, 1907, 1908, and 1909 various supplementary dredg- 
ings were carried on with both the Fish Hawk and the Phalarope, and at least 150 sta- 
tions were dredged. These were in most cases more or less approximate repetitions of 
stations of the regular series. On most of these occasions search was made only for 
particular species, and no list was kept of the entire collection of organisms brought 
up. In the case of the hydroids, Bryozoa, and Foraminifera, however, and of unusual 
species belonging to any group, the records derived from these supplementary stations 
are to a large extent included with the others, the year of the dredging being indicated. 
During the summer of 1909, 26 of the earlier stations in Buzzards Bay (mainly of the 
Fish Hawk series) were repeated with rough approximation by the Phalarope, and 
fairly full lists were made of the organisms taken at each.? These lists have been 
appended to the regular series. Several trips were likewise made during the summer of 
1907 for the special purpose of collecting alge. 
To what degree the earlier records have been confirmed or corrected by these sup- 
plementary dredgings will appear from time to time in the special discussion relating 
to particular species. It may be noted in passing, however, that the later operations 
have added very materially to the accuracy of our results as a whole. 
A chart (no. 226) has been prepared indicating the position and, so far as possible, 
the direction and extent (see p. 18) of the dredgings of the survey. Upon this chart 
the stations are numbered, these numbers corresponding to those given in the lists. The 
numbers employed are arranged consecutively according to date. They do not there- 
fore bear any necessary relation to the position of the stations. In order to facilitate 
the finding of a given station by the reader the following general statements are offered: 
(1) The Fish Hawk stations are all indicated by numbers of four digits, commenc- 
ing with 7, thus: 7521, etc. The Phalarope and Blue Se stations are indicated by 
numbers ranging from 1 to 167. 
(2) Fish Hawk stations are designated either by a circle or by a chain of two, 
three, or four smaller circles, connected by a straight or curved line (see p. 18). Phala- 
rope and Blue Wing stations are designated by arrows, which show the direction of 
the haul, and, very roughly, its relative duration. These last are in all cases near shore, 
except for a few upon the Middle Ground shoal at the eastern end of Vineyard Sound. 
(3) Fish Hawk stations 7521 to 7602 are in Vineyard Sound, commencing near 
Nobska Point and running to the westward. They are arranged at intervals of about 
three-fourths of a mile along lines crossing the Sound at a distance of about 1 mile from 
one another. Near the western end of Vinevard Sound three of these lines are num- 
bered in a reversed order, i. e., stations 7581 to 7587 are along the line connecting Gay 
Head and Cuttyhunk, the next stations in serial order, being upon a Jine passing from 
Nashawena to a point about 1 mile east of Gay Head. 
(4) Stations 7603 to 7609, inclusive, are at Crab Ledge (see chart 223), and are 
therefore not included upon the present chart. 
(5) Stations 7610 to 7675 are in Buzzards Bay—7610 to 7635 are in the upper 
half, SRLOE from a ae near ues co face to re: are in wes lower ae 
a Certain groups, however, did not receive adequate attention, and comparativ Ds few of these specimens were ated. to 
specialists for identification.
