Sub-family Nudocotylinae . . 7 



Uterus in anterior body half Nudocotyle Barker 1916 



The Notocotylidae are up to the present represented in North America 

 by two species of Notocotylus and one species of each of the other genera in 

 this family. 



The Notocotylidae were subdivided by Kossack (1911) into two sub- 

 families; Notocotylinae including Notocotylus Diesing (1839) Catatropis 

 Odhner (1905) and Paramonostomum Liihe (1909), and Ogmogasterinae 

 represented by a single species Ogmogaster plicatus (Creplin 1829) Jager- 

 skiold 1891. A third subfamily Nudocotylinae was created by Barker 

 (1916) to hold Nudocotyle nomcia. In this Barker would include Barisomum 

 erubescent Linton (1910). 



NOTOCOTYLINAE Kossack 1911 



Small to medium sized Notocotylidae with thin cup-shaped body; two 

 to five rows of prominent papillae on ventral surface. Genital pore median, 

 near intestinal bifurcation. Cirrus pouch enclosing only a small part of 

 seminal vesicle. Vitellaria well developed occupying a region posterior 

 to middle portion of body anterior to testes and lateral to intestinal crura. 

 Ovary and testes symmetrical, in extreme posterior part of body. Ovary 

 between testes and separated from them by intestinal crura. Uterus regu- 

 larly coiled, between intestinal crura. 



Type genus Notocotylus. Other American genera Catatropis and 

 Paramonostomum. 



NOTOCOTYLUS Diesing 1839 

 Syn: Notocotyle Diesing 1850 



The genus Notocotylus was formed by Diesing in 1839 to include 

 Fasciola verrucosa Frolich, Fasciola anseris Gmelin, Festucaria pedata 

 Schrank and Monostoma verrucosum Zeder. It was characterized by the 

 author as follows: "Corpore oblonga-ovato, depressiuscula, antice parum 

 attenuate, postice rotundato, ore terminali orbiculari; acetabulis suctoriis 

 dorsalibus numerosis, serie triplici longitudinali; cirro longo spirali ven- 

 trali." In 1850 the author changed the name to Notocotyle with only a 

 slightly modified diagnosis as follows: "Corpus oblongum depressum. 

 Caput corpore continuum. Os subterminale anticum. Acetabula numerosa 

 (24-50) juxta totam dorsi convexiusculi longitudinem treseriata sissilia, 

 orbicularia, limbo callosa. Penis ventralis superus longi spiralis. Porus 

 excretorius .... In avium intestinis crassis et coecis endoparasita!" 

 Under this caption Diesing included his former genus Notocotylus. Altho 

 Monticelli, Barker and others adhere to the more recent form of the name
