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.” 
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.

Family AsconidiE. 
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. 741, 391 (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 SyconidiE. 
? Grantia ciliata (Fabricius) [Chart 10.] 
Verrill and Smith, 1873, p. 740, 330, 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 
? Grantia ciliata — Continued. 
Bay and near its mouth; dredged in 1 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.

a Specimens from points designated by an asterisk (*) were referred to Dr. J. A. Cushman lor identification, 
b 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.
