PARASITES OF FISHES OF BFAI'KoRT, NORTH CAROLINA. 389 



1902. — Aug. 15, 2. Aug. 22, .".. The intestine was very indistinct, but the oesophagus was 

 evidently very shorl or none. Dimensions, life, in millimeters: Length 1, breadth 0.5; transverse 

 diameter of oral sucker 0.1 1. of pharynx 0.05, of ventral sucker 0.22: ova i average of two) 0.0S by 0.04. 



14. DiMomum sp. [Figs. 168, 169.] 



These differ from the foregoing mainly in the position of the testes. 



1901. — Aii>;. 15, 1. Dimensions, life, in millimeters: Length 0. si, breadth 0.42; oral sucker 0.12, 

 pharynx 0.06, and ventral sucker 0.17 in diameter; ova 0.063 by 0.035. Aug. 16, 2. Aug. 21, 3. 



1902.— July 17, few. July 19, 1. July 21, 1. July 29, Aug. 4 and 19, few. The testes in some 

 are placed somewhat diagonally. 



15. Distomum pectinatum sp. now [Figs. 200-203.] 



Body elongate, somewhat fusiform, color white, except where the yellow- ova show through the 

 translucent walls. Neck narrowing to head, very fragile, and provided with 12 fleshy, papillary lobes, 

 6 on each side ju.st hack of the head. There are also 14 similar lobes, making a crown dorsal and 

 lateral on the head; otherwise the worm is smooth. Ventral sucker much larger than the oral, and 

 situated about the anterior third; pharynx cylindrical, its anterior end touching the oral sucker; 

 oesophagus long; rami of intestines simple, slender, beginning at anterior edge of ventral sucker and 

 extending to posterior end of the body. Testes 2, subglobular, at posterior end of body, near together 

 and placed a little diagonally. Cirrus-pouch rather large, with coiled cirrus, on left side contiguous to 

 the anterior edge of the ventral sucker; genital aperture in front of ventral sucker on left of median 

 line. Ovary in front of testes, as far as or farther than the diameter of a testis, and on the right of the 

 median line. Uterus very voluminous, filling the body from the posterior testis to the ventral sucker, 

 and extending thence laterally to t lie cirrus on the left side to the genital aperture. Vitellaria distributed 

 laterally from the anterior testis nearly to the ventral sucker. They appear to be much reduced in 

 the specimens studied. Ova minute, of two kinds, oval and nearly spherical, the latter larger than 

 the others and seen near the middle of the body. 



Dimensions in millimeters, life, specimen collected Aug. 10, 1901: Length 2.1; greatest breadth, 

 specimen compressed, 0.38; oral sucker, length 0.12, breadth 0.10; pharynx, length 0.21, breadth 0.11; 

 ventral sucker, length 0.28, breadth 0.25; most of the ova 0.022 by 0.015 in the two principal diame- 

 ters; a few were seen which were nearly spherical, about 0.01S by 0.017. The head and especially the 

 neck quickly macerate. 



1901. — Aug. 10, 2, much macerated. Aug. 12. 5. Aug. 13, 18. Aug. 15, 8. Aug. 16, 1. Aug. 

 21, 3. Aug. 22, 20. 



1902. — July 16, 1. July 17, 8. July 19, numerous, one small piece of the intestine 4 mm. in length 

 yielded 10. July 21, S. July 25, 10. July 29, 10. Aug. 4, 5. Aug. 5, 6. Aug. 8, 40. Aug. 11, 5. 

 Aug. 12, 3. Aug. IS, 6. Aug. 19, 17. Aug. 21, 6. The specimens collected on Aug. 6 were more 

 slender than the type but do not appear to be specifically different. 



16. Distomum areolatum Rudolphi. 



1902. — Aug. 8, numerous. These specimens agree closely with the species which I have referred 

 in former papers to /'. areolatum. Dimensions of a living specimen, slightly compressed, in millime- 

 ters: Length 0.7o, breadth 0.40; diameteroforalsuckerO.il, pharynx 0. 05; ventral sucker 0.0s. The 

 one ovum measured 0.12 by 0.07 in the two principal diameters. 



COPEPOD I'AUASITES. 



17. Caligussp. 



1902. — July 16, 1. Found in washings from intestine but doubtless from outside of its host. 



18. Parasitic rope/ mi I (Lernanthropus). 

 1902.— Aug. 19, 2. Aug. 21, 1; from gills.
