BIOLOGICAL SURVEY OF WOODS HOLE AND VICINITY. 
563 
Hydractinia echinata — Continued , 
Cancer irroratus, stems of rock-weed, carapace 
and legs of Limulus (Hargitt). During the 
survey dredging it was found upon two sticks 
of wood brought up from the bottom near 
Menemsha Bight, also from the shell of a 
living Buccinum undatum. Regarding an 
interesting mass of these organisms found at 
Vineyard Haven, in August, 1906, Dr. Osbum 
has furnished the following notes: “One old 
pile, broken off just at low water, was entirely 
incrusted, almost to the exclusion of all else, 
with a colony of Hydractinia polyclina . . . 
The colony extended from just below low 
water to over a fathom’s depth and covered 
many square feet.” The following is probably 
a very incomplete list of stations at which this 
species was dredged:

Harbor and Eel Pond, April to August. — C. 
W. Hargitt. Dr. Mayer reported this species 
as common in Woods Hole Harbor, March 4, 
1907, while Mr. G. T. Hargitt found it in 
abundance from April 5 to n, 1908. Accord- 
ing to Mr. Edwards’s towing records, it is 
most common in April, though taken from 
February to August and occasionally at other 
times.

Hydroids generally distributed in shallower 
waters upon piles, rock-weed and floating 
timber; not recorded in the Survey dredging. 
Medusa common in summer, occurring during 
August and September (Verrill); as early as 
June (Hargitt). Mr. G. T. Hargitt found a 
few specimens early in April (1908) which he 
referred to this species. 
Bougainvillia superciliaris Agassiz.

only). — Nutting. Medusae taken in April, 
May, and June (Verrill); August 11, 1899

ber. — Mayer. 
Calyptospadix cerulea Clarke. 
Hargitt, 1909, p. 371. 
Woods Hole Harbor; found by Dr. Hargitt, 
growing on the bottom of the steamer Fish 
Hawk, also on piles of Fisheries pier, August, 
1908. Wareham, on bridge, August, 1908; 
“fine colonies” collected by V. N. Edwards, 
identified by C. W. Hargitt. During follow- 
ing summer no specimens were taken in 
Woods Hole Harbor, but “ luxurious colonies” 
were again taken at Wareham. 
Dr. Hargitt believes that this species has but 
recently established itself in the region.
