The number without brackets in the given table just as in the following tables 

 and in the text indicates the total number of species independently of the fact 

 as to whether or not they are also encountered on other groups--families, 

 orders of hosts; the number in brackets indicates the number of species 

 discovered only in the given group. Thus, from five species of Ancylodiscoides 

 known from Bagridae, four were discovered only in this family and one was 

 also found on Silurldae. 



In the work of Pearse (1949) a new species of Monocotyle, included by us in the 

 total number of Monogenoidea, is described but it is not considered here. The 

 fact is that the description and drawing of this species are such that we are not 

 in a position to determine its generic affinity. If what the author writes about the 

 armature of the attaching disc of the given species in true then it must be some- 

 thing connpletely new and at any rate not having the slightest relation to the genus 

 Monocotyle.
