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. Osburn 

 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 :

Medusa at Newport. Fewkes. Woods Hole 

 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. 



Boiigainvillia superciliaris Agassiz.

 only). Nutting. Medusae taken in April, 

 May, and June (Verrill); August n, 1899 

 (Nutting); "June to September" (Hargitt). 



Bougainvillia autumnalis Hartlaub. 



Mayer, 1900, p. 5 (Bougainvillia gibbsi); Hargitt, 

 1904, p. 40 (Bougainvillia gibbsi); Mayer,

Medusa taken at Newport, from July to Octo- 

 ber. Mayer.

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.
