TABLE SHOWING- THE DERIVATION AND EQUIVALENCE OF ALL FIG- 

 URES IN THIS PAPER REPRODUCED FROM PREVIOUS AUTHORS. 



The following table shows tlie equivalence of all figures in the litera- 

 ture, including those of species formerly considered myxosporidian but 

 now rejected. Figures to the right are copied from those farther to the 

 left on the same horizontal line, and those copied in this paper are, in 

 all cases, taken directly from the original. Further, wherever several 

 series of letters or figures (indicated, for economy of space, as "«-m " "1- 

 16, etc.) occur on the same horizontal line, the individual members of 

 such series correspond alivays and rigidly each to each, that is, a to a, 

 htob,l to 1, 2 to 2, or 7 to 10, 8 to 11, etc., as the case may be. To 

 save space all intermediate columns not required on any particular 

 page are omitted from that page. Such omitted columns will of course 

 appear on some other page, and their relative positions in the full 

 series of illustrated articles represented in this table, are indicated by 

 the bibliographic reference number (Eoman numerals). Plate numbers 

 (heavy type) are inserted only where absolutely necessary to prevent 

 ambiguity. 



After much study of the literature certain figures can not now be 

 placed with any certainty. They aie those to which no species number 

 corresponds in the table. It will be seen that they are principally some 

 of Pfeifter's and Balbiani's and are mainlj^ to be distributed between the 

 two probably very distinct but at present not very clearly delimited 

 species habitant on the tench, Myxoholus piriformis and 31. ellipsoides. 

 On the plates I have thought it best to reproduce the groups of figures 

 entire and to leave to the future the apportionment of the individual 

 figures, and will only add that in the synonymy of 31. piriformis and 3f. 

 ellipsoides I have ventured on a taxonomic guess, the dubious figures 

 being sei)arated from those definitely ijlaced by a period or a paren- 

 thesis.
