LIST OF SPOROZOAN SPECIES. 



1, Ceratomyxa acadiensis n. sp. 



The Myxosporidium (PI. IV Figs. 1-5, 10-13) is typically club-shaped with a 

 long tail, often many times the length of the thicker part of the body (PI. IV, Fig. 

 10). Large individuals may be irregularly stellate (PI. IV, Fig. 12). The 

 pseudododia often show a rigidity as if possessed of a rigid endoplasmic axis. 

 The protoplasm of certain of the pseudopodia may be collected into clumps, the 

 clumps being connected together by thin hyaline filaments of ectoplasm. A 

 division into ectoplasm and endoplasm though not always clear is often to be seen 

 in the anterior rigion. In the parasite of Urophycis chuss the mxyosporidia were 

 very often found attached to the myxosporidium of an undetermined species 

 (PI. IV, Fig. 7 and 8) described in the fourth part of this section. An examin-
