 "Common on Bryozoa at Woods Hole." 



Acineta tuber osa Ehrenberg.

 U. S. Bureau of Fisheries pier. 



Family DENDROSOMID/E. 



Trichophrya salparum Entz. 

 Calkins, 1902, page 466. 



Woods Hole. "This species was found by Dr. 

 G. Hunter on the branchial bars of the Ascidian 

 Molgula manhattensis, where great numbers of 

 them are often parasitic." 



Class SPOROZOA. 



Family POLYCYSTID^. 



Gregarina gigantea Van Beneden. 

 Herrick, 1895, page 122. 



Host, the lobster. Not specifically recorded 

 for this region. 



Family MYXOBOLID^S. 



Myxobolus linioni Gurley. 



Linton, 1891; 1900, page 277; 1901, p. 442. Gur- 

 ley, 1893, page 414 (sp. nov.); 1894, page 238. 



Host, Cyprinodon -variegatus, upon which it 

 occasionally gives rise to wartlike excres- 

 cences. Linton, Gurley. 



Sporozoa undetermined. 



Dr. Linton (MS. notes) records undetermined 

 monocystid gregarines from the spiral valve 

 of the mackerel shark (Isurus dekayi), and un- 

 determined Myxosporidia from the eel (An- 

 guilla chrysypa), the menhaden (Brevoortia 

 tyrannus), the squeteague (Cynoscion regalis), 

 the halibut (Hippoglossus hippoglossus), the 

 silverside (Menidia menidia notata), the smelt 

 (Osmerus mordax), and the mackerel (Scomber 

 scombrus). Mr. C. W. Hahn and others have 

 likewise found Myxosporidia in local fishes of 

 a number of species, but the results of their 

 work are not yet available. 



Phylum PORIFERA.' 



Family ASCONID^. 



Ascortis fragilis Haeckel. 



Verrill and Smith, 1873, p. 741. 



Vineyard Sound. Verrill. Western end of 

 Vineyard Sound, at two stations* (Fish Hawk 

 7720 and Phalarope 32); 5 to 13 fathoms. 

 Leucosolenia sp. 



Verrill and Smith, 1873, P- 74*. 39* (Leucosolenia 

 botryoides?). 



Verrill doubtfully identified a species found in 

 this region and said to be very common on 

 piles. Specimens which were provisionally 

 assigned to this genus by the collectors were 

 taken at several dredging stations. 



Family SYCONID^. 



? Grantia ciliata (Fabricius) [Chart 10.] 

 Verrill and Smith, 1873, P- 74, 33, etc. (" Prob- 

 ably the same as the Grantia ciliata of 

 Europe.") 



"Vineyard Sound, not uncommon." Verrill. 

 Vineyard Sound, particularly at the eastern 

 and western extremities ; scattered sta- 

 tions along the eastern shore of Buzzards 



f Grantia ciliata Continued. 



Bay and near its mouth; dredged in i to 19 

 fathoms on non-muddy bottoms. Survey. 

 Grantia is found most abundantly, however, 

 on the piles of piers, in which situations it is 

 common in Woods Hole Harbor and is doubt- 

 less of very general distribution throughout 

 the region.

o Specimens from points designated by an asterisk (*) were referred to Dr. J. A. Cushman for identification. 

 6 Identified in most cases without careful inspection, it being assumed that only one species of Grantia occurs locally. It is 

 not wholly certain, however, to what species these specimens are to be referred, or even whether they are all of the same species.
