 but so far as known it does not play any important

 several new propositions are made concerning certain 

 parasites mentioned in this report.

 dotaeniae, is changed to Dipylidinae. This change is 

 in accordance with the International Code and should 

 be adopted, the word, however, being written Dipyli- 

 diinae. 



Choanotaenia : Railliet proposes a new genus, with 

 Taenia infundibuliformis Goeze as type, in the follow- 

 ing words:
