length, 0.17 mm., breadth, 0.22 mm.; pharynx, length, 0.1 mm., 

 breadth, 0.11 mm. ; ventral sucker, length, 0.31 mm., breadth, 0.42 mm. ;

From the puffer: Recorded by Linton {Distomwm mtellosum)^ 

 Bull. U. S. Fish Comm. for 1899, p. 464, 1901. One, partly macer- 

 ated, collected August 2, 1907. One, small, collected August 10, 1907. 

 Three, collected June 8, 1914 ; largest, in formalin, 4.5 mm. One, col- 

 lected June 8, 1916. These specimens in balsam are somewhat shriv- 

 eled, but are in suiSciently good condition to identify. The ovary is 

 lobed and pestle-shaped, and the vitellaria are interrupted opposite 

 the testes. 



From the goggler: One (U.S.N.M. No. 8245), collected September 

 13, 1915; length, in formalin, 5 mm. Measurements in balsam: 

 Length, 4.76 mm., breadth, 0.56 mm.; diameter of oral sucker, 0.2 

 mm., of pharynx, 0.11 mm., of ventral sucker, 0.35 mm., of first 

 testis, 0.35 mm.; ova, 0.078 by 0.045 mm. Cirrus exserted, smooth, 

 length, 0.23 mm. ; diameter at tip, 0.04 mm., at base, 0.06 mm. ; ovary 

 trilobed ; vitellaria interrupted at level of testes. 



From the garfish {Strongylura maHna) : Two, collected October 9, 

 1915; length in formalin, 3.82 mm. One, collected July 12, 1926. 

 Measurements in balsam : Length, 3.1^ mm., breadth, 0.52 mm. ; 

 breadth of oral sucker, 0.17 mm., of pharynx, 0.13 mm., of ventral 

 sucker, 0.27 mm. ; ova, 0.08 by 0.045 mm. 



PODOCOTYLE species 



Plate 22, Figure 288 



Body slender, greatest breadth at about level of ventral sucker; 

 diameter of ventral sucker about twice that of oral sucker ; diameter 

 of pharynx about half that of oral sucker; prepharynx short; 

 esophagus as long as or longer than pharynx ; intestines extend nearly 

 to posterior end. Genital pore in front of ventral sucker, a little 

 to right of median line ; cirrus pouch extends back of ventral sucker, 

 on the left side ; seminal vesicle at base of cirrus pouch ; testes rela- 

 tively large, the first rounded and slightly lobed, the second some- 

 what rhomboidal; ovary in front of first testis, short pestle-shaped, 

 the posterior end 3-lobed; seminal receptacle on right side of ovary; 

 shell gland in front of ovary ; uterus between shell gland and ventral 

 sucker; no ova in uterus; one ovum noted in shell gland, about 0.024 

 by 0.015 mm., probably not to be regarded as a fully formed egg; 

 vitellaria extend from about the level of the posterior edge of the 

 ventral sucker to the posterior end, interrupted at level of testes, but 

 follicles lying between the testes and between the first testis and 

 ovary.
