 papillae were noted behind the posterior edge of the ventral sucker. 



From four-spotted flounder: One, collected August 4, 1905. 



From spotted codling: Seven, collected October 19, 1908; 1.5 to 

 3.5 mm. in formalin. Eleven, collected October 23, 1913. Ten 

 (U.S.N.M. No. 8255), collected November 12, 1915. Dimensions in 

 balsam : Length 1.26 mm., breadth 0.32 mm. ; oral sucker, length 0.09 

 mm., breadth 0.1 mm. ; pharynx, length 0.08 mm., breadth 0.08 mm. ; 

 ventral sucker, length 0.15 mm., breadth 0.16 mm.; ova 0.54 by 

 0.27 mm. 



From codling: Six, collected August 4, 1911; 3 fishes examined. 

 Dimensions in balsam: Length 1.93 mm., breadth 0.56 mm.; oral 

 sucker, length 0.11 mm., breadth 0.1 mm.; pharynx, length 0.1 mm., 

 breadth 0.08 mm.; ventral sucker, length 0.21 mm., breadth 0.18 

 mm.; ova 0.048 by 0.027 mm. One (U.S.N.M. No. 8256), collected 

 November 3, 1913; length in formalin 2.25 mm.; 4 fishes examined. 

 One, collected July 30, 1929; length in balsam 1.68 mm.; 3 fishes 

 (15-20 cm.) examined. 



From bluefish: Bull. U. S. Fish Comm. for 1899, p. 451, figs. 

 337-339, 1901. A few, collected July 15, 1904. One, collected Au- 

 gust 11, 1904, from intestine. One (U.S.N.M. No. 8257), collected 

 July 1, 1910. Dimensions in balsam, lateral view: Length 3.38 

 mm., breadth 0.56 mm.; oral sucker, length 0.2 mm., breadth 0.15 

 mm.; pharynx, length 0.17 mm., breadth 0.12 mm.; ventral sucker, 

 length 0.29 mm., breadth 0.31 mm. ; ova 0.048 by 0.024 imn. ; ventral 

 sucker pedicillate, with 5 digitate lobes at its posterior border ; ovary 

 ellipitical; testes triangular in outline. One, collected August 27, 

 1910. A few, collected July 17, 1911; one of these in balsam shows 

 distinct lobes on anterior border of ventral sucker and less distinct 

 lobes on posterior border. In specimens flattened, and viewed either 

 from the dorsal or the ventral side, these lobes are difficult to dis- 

 tinguish. 



From alewife : Bull. U. S. Fish Comm. for 1899, p. 439, 1901. One, 

 collected July 26, 1910; length, 1.6 mm.; breadth, 0.53 mm., life, 

 compressed. One, collected August 17, 1910; length, 1.85 mm. 

 Eleven, collected October 19, 1914. In one specimen, mounted in 

 balsam, lateral view, blunt papillae around the ventral sucker are 

 plainly shown; in the others, ventral view, they are not visible. 

 Measurements in balsam: Length, 1.46 mm., breadth, 0.43 nmi.; oral 

 sucker, length, 0,11 mm., breadth, 0.10 mm.; pharynx, length, 0.08 

 mm., breadth, 0.08 mm.; ventral sucker, length, 0.18 mm., breadth, 

 0.14 mm. ; length of esophagus, 0.11 mm. ; ova, 0.051 by 0.027 mm.
