395] ANOPLOCEPHALIDJE—DOUTHITT 45 



Diamare (1900) who was first to give more than mention of the 

 Monieziae from birds, created the genus Paronia for the species he was 

 considering (Moniezia carrinoi). His conclusions, however, were not 

 based upon a sufficient knowledge of the cestodes in question or the 

 Anoplocephalidae in general, and Fuhrmann very properly included 

 this cestode and other related ones which he described in the genus 

 Moniezia. If, however, the additions here made to the knowledge of 

 Moniezia expansa should hold true for the other Monieziae from mam- 

 mals, there seems to be little question but that the genus Paronia should 

 be revived for the forms from birds. It would be rash to conclude, 

 however, that the other Monieziae from mammals agree with M . expansa 

 in this regard. If one considers the different members of the genus 

 Schizotaenia, one finds as great a diversity in uterine structure as is here 

 exhibited. As to the other differences noted, they are not by themselves 

 sufficient reasons for the separation of the genus Moniezia, since other 

 Anoplocephalid genera show both conditions for each structure. Any 

 division of the genus Moniezia would seem premature, therefore, with- 

 out first examining several species. Consideration of this step is left 

 to some worker who has access to such material. 



For reasons stated on page 49 I have transferred Zschokke's 

 "Moniezia" diaphana to the genus Cittotaenia. Von Janicki's descrip- 

 tion of M. beauforti is not accessible to me; but since it is an avian 

 parasite, it is here considered as belonging in the carnnoi-group I can 

 not find evidence to support Parona's action in placing Taenia frontina 

 (Dujardin 1845) in this group. Until something more is known of this 

 cestode it should by all means be left where it will do no harm. The 

 genus Moniezia as here accepted includes therefore the following species : 



1. Carrinoi-group M. columbae Fuhrmann 

 M. carrinoi Diamere M. variabilis Fuhrmann 

 M. ambigua Fuhrmann M. beauforti von Janicki 



2. Expansa-groxvp 



M. expansa Rudolphi M. neumanni Moniez 



M. trigonophora Stiles and M. alba Perroncita 



Hassall M. amphibia von Linstow 



M . oblongiceps Stiles and M. rugosa Diesing 



Hassall M. f estiva Rudolphi 

 M. planissima Stiles and Hassall 

 M. benedeni Moniez 



Apparently in all Monieziae the oviduct connects with the ovary 

 directly in front of the vitelline gland and the uterus crosses the excre-
