Cordylophora lacustris Allman.

species undetermined); Nutting, 1901, p. 
327; Hargitt, 1908, p. 99. 
“ Found in a fresh- water pond near the [Nobska] 
bathing beach by A. D. Morrill.” — Nutting. 
Taken by Hargitt "in several similar ponds 
in the region and near Falmouth, and in fresh 
or brackish ponds on Marthas Vineyard.” 
Collected by Dr. Congdon at Tashmoo Pond, 
Great Pond, and Weweantic River, and by 
Mr. Edwards at Fresh Pond (Falmouth) and 
Oyster Pond. 
"The reproductive season seems to be chiefly 
in spring or early summer, and sparingly in 
July. Colonies have been found later, Sep- 
tember or October, but with no signs of gono- 
phores. ” — Hargitt.

Hydroids on Bureau of Fisheries pier, at 
Woods Hole. — Bumpus, Mead. Waquoit. —

Hole Passage. — G. M. Gray. Medusae re- 
ported locally by various observers. 
"Breeding hydroids” in March. — Bumpus. 
In April (1898), according to Mead, the 
hydroids “occurred in colonies that could be 
measured by the square yard;” these disin- 
tegrated later. Dr. A. G. Mayer found the 
medusa to be common in Woods Hole Harbor 
on March 4 (1908); while Dr. Mead and Mr. 
G. T. Hargitt report its occurrence during 
April. According to Mr. Edwards’s towing 
records it is commonest during April and May, 
though taken occasionally in other months. 
The seasonal range is stated by Dr. C. W. 
Hargitt as extending from February to May. 
Syncoryne producta Hargitt. 
Hargitt, 1902a, p. 550 (Coryne producta, sp. nov.); 
Hargitt, 1904, p. 30; Mayer, 1910, p. 63 (Sarsia 
hargitti).

?Corynitis agassizii McCrady. 
Bumpus, 1898b, p. 857; Murbach, 1898, p. 354; 
Nutting, 1901, p. 329, 372; Hargitt, 1904, p. 
42; 1908, p. 100; Mayer, 1910, p. 72. 
Murbach reported the occurrence of “ Corynitis 
agassizii ” upon floating sargassum from Vine- 
yard Sound. Hargitt has shown, however, 
that these observations refer to an entirely 
different species, Gcmmaria gemmosa McCrady, 
which Murbach endeavored to identify with 
Corynitis agassizii. Dr. Hargitt knows of no 
authentic records of the occurrence of the 
latter species at or near Woods Hole. The 
reader is referred to the conflicting statements 
of Hargitt, Murbach, and Mayer in the papers 
cited. 
Family Cbadocorynid^. 
Cladocoryhe floccosa sargassensis Hargitt. 
Hargitt, 1909, p. 369 (var. nov.). 
A form thus designated by Dr. Hargitt was 
taken on floating sargassum in Vineyard 
Sound during the summer of 1907.

A. Agassiz. Newport. — Fewkes. Woods Hole 
and vicinity, in midsummer, common. — 
Hargitt. 
J. P. McMurrich (in Marine Biological Labora- 
tory card catalogue) records having obtained 
ova on August 7 (1893). 
Of the “Dipurena conica” of A. Agassiz, Hargitt 
writes: "It seems altogether probable . . . 
that we have here simply a varietal form, 
which would hardly justify specific separation, 
and should probably be included under the 
above species.”
