BULLETIN OF THE BUBEA.U OF FISHERIES. 



11. Distomum (?) sp. [Fig. 215.] 



1901. — Aug. 27, 1, pale red, thick, dorsal surface roughly nodular. In lateral view about live 

 papillae visible on the side, back of middle. When the worm was placed on the slide it lay on its 

 side, in which position it was studied. While it was under the cover glass a white excretion was 

 forced from the posterior end in a slender thread, probably from the excretory vessel. Dimensions, in 

 millimeters, side view: Length 2.8; diameter, anterior 0.42, middle 0.70, posterior 0.12. 



12. Distomum sp. 



A small fusiform distome. Aug. 8, 1902; 1. Dimensions, life, in millimeters: Length 0.7; breadth, 

 at anterior end 0.09, at ventral sucker, near middle and maximum, 0.3, tapering to posterior end; oral 

 sucker, length 0.07, breadth 0.06; pharynx, length 0.06, breadth 0.05; ventral sucker, length 0.12, 

 breadth 0.16; ova 0.029 by 0.018. 



This species resembles D. bothryophoron. 



13. Kstomumsp. [Figs. 167, 205.] 



A small, oval, minutely spinose distome resembling D. pyriforme Linton, but with smaller, more 

 numerous and distinctly fusiform ova. Dimensions, life, in millimeters: Length 0.5; breadth 0.3; 

 diameter, of oral sucker 0.09, of pharynx 0.04, of ventral sucker 0.06; ova 0.029 by 0.018. 



In fig. 167 the specimen is compressed more than in fig. 205. 



14. Gasterostomum gracilescem Rudolphi. [Figs. 238, 239.] 



1902. — Aug. 8, several, small, oval, very minutely spinose, immature. Dimensions, in millimeters: 

 Length 0.0; diameter, middle and maximum 0.45; diameter of anterior sucker 0.21, of mouth 0.09. 



Sec under Merddia, Tylosurus marinus, etc. 

 L5. Vonostomum vinal-edwardsii Linton. [Figs. 220-221.] 



1901. -July 9, 1. July 16, 5. July 18, 5. Aug. 3, 1. Aug. 16, 8. Aug. 22, 6. Aug. 27, 8. 

 Aug. 30; 2. The excretory vessels of the neck seen in ventral view appeared to be enlarged into oval 

 sacs at their inner ends and terminated at the surface in minute tubes. 



1902.— July 14, 11. July 16, 7. July 22, 5. July 26, 1. July 20, 4. July 30, few. Aug. 8, 5 of 

 usual size, length 1.8 mm., breadth 1.14 mm.; 1 smaller, length 0.42 mm., breadth 0.25 mm. Aug. 

 11, 11. Aug. 16, 1. Aug. 18, 3. Aug. 20, 1. 



Hypsoblennius hentz, Blenny. 



No L-iitozoa found. 



Paralichthys dentatus, Summer Flounder. 



It is probable that some of the flounders recorded under /'. albiguttus belong here, as they were 

 not always examined critically. Both species of flounder are common at Beaufort, and, moreover, 

 are very much alike. 



ACANTHOCEPHALA. 



1. Echinorhynchus sagittifer Linton. 



Aug. 1; 1, immature, from mesentery.
