Conjugation in myxosporidia. .-1 to /, Myxobolus pfeifferi, Th. (after Keysselitz); K to <2, 

 Spheromyxa labrazesi, Lav. and Mes. (after Schroder); .4, B, formation of gametoblasts; 

 C to G, union of sporocysts and multiplication of nuclei; H, young sporoblast with polar 

 capsules forming and gametic nuclei not yet united; /, spore with capsules (not filled in) and 

 gametic nuclei united; K, young pansporoblast of spheromyxa, with dimorphic nuclei; L, pan- 

 sporoblast with fourteen nuclei; M , pansporoblast divided into sporoblasts, each with two 

 pole capsules (p), four globules present (x) and with two central reduction nuclei; N, sporo- 

 blasts having two shell nuclei (s), two polar capsules, each with a nucleus and two germ nuclei;
