Rhynchobothriuru remained attached when it was forced out by pressure. A few eneapsuled nematodes 
among the cysts on the mesentery, the intestines of which were somewhat folded or crumpled, white 
by reflected and pale reddish or yellowish brown by transmitted light. 
26. Stenotomus chrysops, Sc up. 
(1) .July 19; sixteen, about two years old; stomachs empty. Several nematodes and a few cysts 
on serous covering of viscera. Small cestode larvae, similar to those found in squeteague, flounder, 
etc., in intestine. 
(2) .June 14; small nematodes and cysts from body cavity, collected by Dr. F. P. Gorham, agree 
with lot (1). 
(3) July 25; two; stomachs contained annelids and amphipods. Cestode cyst and nematodes 
on viscera — same as lot (1). 
Leech, slender, yellowish-brown, with three longitudinal rows of white blotches, one on each side 
and one dorsal, about eighteen in each row ; suckers bluish-white. Although this leech was found on 
the soup, it probably came from one of two flounders which were in the same pail with the scrip. In 
the same pail were, in addition to these, an eel, a blue-fish, and two sea-robins. 
(4) July 26; one; stomach with young squid. A few nematodes on viscera, same as in lot (1). 
(5) August 4; one; small globular cysts in kidneys, collected by Mr. E.E. Tyzzer. See page 301 
for description. 
(6) August 5; two; stomachs empty. Small immature nematode on mesentery. Dimensions, in 
millimeters: Length (alcoholic), 9. Other dimensions from life. The worm was transparent, and the 
brownish intestine had an anteriorly projecting diverticulum 0.14 in length; length of (esophagus, 
1.42; head with prominent papilla on ventral lip and two others less distinct; posterior end slender 
acuminate; distance from anal aperture to posterior end, 0.14. 
(7) August 15; two; stomachs contained hydroids (Pennaria). Two small nematodes and one 
small distomum from viscera. The body of the distomum was covered with minute scale-like spines. 
For further details see page 296 (fig. 72). 
(8) August 22; thirty-oue; stomach contents not noted. Careful search was made in the hope 
of getting more examples of the distomum found in (7). Only a few small, immature nematodes and 
encysted larval Rliynchohothria found. The latter agree with the form described in my Notes on 
Larval Cestodes of Fishes, pp. 796-797, plate lxiii, figs. 9-13. 
27. Cynoscion regalis, Squeteague. 
(1) July 18; two; stomachs empty. 
Cestodes: Larval Rhynchobothria in cysts on viscera. Larval cestodes in gall bladder, very 
numerous in one, attached in clusters to mucous lining of gall bladder; m the other few. (Larval Ces- 
tode Parasites of Fishes, pp. 789-792, pi. lxi, figs. 4-15.) 
Nematodes: Numerous in cysts on viscera. These were small, immature, for the most part of a 
brown color, especially those recently liberated from cysts. 
(2) July 19; five; stomachs contained young herring and butter-fish. 
Cestodes: Numerous cysts containing larval Rhynchobothria and Tetrarhynchi on serous cov- 
ering of viscera. The usual larval cestodes in gall bladder and cystic duct, the clusters forming 
swellings in the cystic ducts of some, which look as if they might occlude the duct in some cases. 
Nematodes: Numerous immature nematodes encysted on serous membrane of viscera. 
Acantliocephala: EchinorhyncUus pioteus. Two of the fish with several specimens in intestine. 
In each case the head and globular bulla had penetrated the. intestinal wall and were protruding into 
the body cavity. (Eutozoa of Marine Fishes, part ill, pp. 537-538, pi. viii, figs. 85-88.) 
(3) July 23; three; stomachs not noted. Cestode cysts ou viscera, especially on mesentery. 
Large numbers of immature nematodes, free and eneapsuled on mesentery. 
(4) July 28; three; stomachs with half-digested fish. Numerous cysts ( Tetrarhynchus ) in stom- 
ach wall ; cystic ducts of two with the usual cestode larvae. 
(5) July 29; eighteen; stomachs with partly digested fish. The usual entozoa in each, viz: 
Tetrarhynchus larvae encysted in the stomach wall. Cestode larvae in cystic duct. Nematode and 
cestode cysts in mesentery. 
(6) Augusts; two; stomachs empty. Cystic ducts with the usual larval cestodes, free in the 
lumen of the duct and in gall bladder, and loosely attached by their heads to the mucous membrane. 
Masses of cestode cysts and eneapsuled nematodes on mesentery.
