56 ILLINOIS BIOLOGICAL MONOGRAPHS [274 



Testes four lobed, extracecal, lying at the same level in the posterior end of 

 the body. Ovary between the testes and separated from them by the 

 intestinal crura. The three to four lobed ovary is usually elongated antero- 

 posteriorly. The uterus as in other members of this genus is coiled trans- 

 versely between the crura and extends from the level of the ovarian com- 

 plex to the posterior end of the cirrus pouch at the beginning of the second 

 body third. The vitelline glands occupy an extracecal position and extend 

 from the testes to the middle region of the uterine coils which is found in 

 the caudal portion of the second body third. Eggs numerous, medium 

 thick shelled, 20ju in length and approximately twice as long as wide. 

 They possess a long polar filament at each end.

NUDOCOTYLINAE Barker 1919 



Small cup shaped Notocotylidae with thick bodies, without ventral 

 glands. Genital pores separate, ventral, lateral, in posterior half of body. 

 Cirrus pouch pear-shaped, enclosing small portion of seminal vesicle. 

 Vitelline glands strongly developed compact masses, lateral to ceca and 

 anterior to testes. Uterus in transverse folds, in anterior half of body, 

 extending laterally over intestinal crura. 



Type genus: Nudocotyle Barker 1916 



Barker would include Barisomum Linton 1910 in this sub-family. 

 This is a doubtful decision since in the genus Barisomum the genital pore 

 is in the anterior body third and the shell gland lies posterior to the ovary. 

 It possesses in fact certain Notocotylid characters but conforms more close- 

 ly to the Pronocephalidae than to the Notocotylidae in the position of the 

 genital pore, and the character and position of the genital glands. 



NUDOCOTYLE NOVICIA Barker 1916 



Small thick oval worms, 709 to 899/x in length; 500 to 657ju in breadth. 

 Anterior end tapering gradually, posterior markedly truncate. Dorsal 

 surface strongly convex, ventral concave. Body smooth, devoid of ventral 

 papillae or spines. Oral sucker sub terminal, spherical 50 to 65 /x in diame- 

 ter; pharynx wanting; intestinal ceca undulating but without diverticula. 

 Male and female genital pores separate, ventral, lateral, in beginning of 

 posterior body third. Cirrus pouch large, club-shaped, about one- third of 

 body width in length. It lies transversely and median in anterior portion 

 of posterior body half. Cirrus without spines. Testes extracecal in posi- 

 tion, lying in same level in posterior fifth of body, frequently 2 to 5 lobed. 

 Ovary elongated, convoluted or lobed, in extreme posterior end of body 

 between testes and separated from them by intestinal crura. Shell gland
