No. 8.— PYCNOGONIDA COLLECTED AT BERMUDA IN 
THE SUMMER OF 1903. 1 
BY LEON J. COLE. 
The first Pycnogonida reported from Bermuda were two species 
described by Professor Verrill in 1900 (Verrill, :00). The descrip¬ 
tions were based upon two specimens obtained by the party which 
with Professor Verrill visited Bermuda in 1898. During the past 
summer (1903), while enjoying the excellent facilities for collect¬ 
ing offered by the Bermuda biological station for research, special 
search for pycnogonids was made by the writer, and other members 
of the party were kind enough to turn over to him such specimens 
as they found. 
The most noticeable fact in connection with the group was the 
relative scarcity both of species and of individuals. Although col¬ 
lections were made in a great variety of localities,— embracing 
the whole group of islands, the surrounding waters, and even 
the Challenger Bank, some fifteen miles to the southwest,— and 
at depths ranging from between tide marks to 35 fathoms, the 
only places at which Pycnogonida were found were in Harrington 
Sound on hydroids, and in a small ‘cut’ connecting the Sound 
with Flatts Inlet. Altogether only three species were obtained. 
Professor Verrill’s specimens were taken, one in Flatts Inlet, and 
one in Bailey’s Bay; the other specimens which I have exam¬ 
ined, to be mentioned later, had no more definite indication of 
locality than ‘ Bermuda.’ As stated above, all the specimens 
collected this year were found on hydroids, and as hydroids are 
relatively scarce, a corresponding paucity of Pycnogonida might 
be expected. That none were found on the hydroids collected in 
Castle Harbor, where conditions are similar in some respects to 
those in Harrington Sound, may in part be explained by the fact 
that less careful search was made in that region than in the Sound 
and at the Flatts, where the laboratory was situated; for all three 
of the forms are so inconspicuous — two on account of their small 
size and one on account of its protective coloration — that they are
