301] STUDIES ON MYXOSPORIDIA—KUDO 63 



Spore: Size large. Form resembles to that of Z<e/>/o//zeca /»arf a. Dimen- 

 sions: sutural diameter and thickness 13)u, breadth 26^. Polar capsules 

 short oval, with a length of S.ljx, length of polar filament about 130/i 

 (KOH). In the second host, a few normal and numerous abnormal spores 

 with three or four polar capsules were observed. 



LEPTOTHECA INFORMIS Auerbach 



[Fig. 10] 



1910 Leptotheca informis Auerbach 1910b : 770-771 



1912 Leptotheca informis Auerbach 1912 : 42-44 



Habitat: Gall-bladder of Molva vulgaris Flem. and Gadus merlangus; 

 Bergen, Tjorao. ' 



Vegetative form: Young trophozoites with somewhat long and narrow 

 pseudopodia formed of hyaline ectoplasm; movements active. The proto- 

 plasm is differentiated into ectoplasm and endoplasm. When stained, two 

 large (7 to 9ix) and two small (3 to An) nuclei were observed in an individual, 

 lln long excluding the pseudopodia. Sporulating trophozoites are gen- 

 erally round and each forms two spores, which are developed independently 

 to each other (i.e., not in ordinary pansporoblast). Auerbach observed 

 centrosomes in the nuclei of larger type in division. Disporous. 



Spore: Large and heavily built. Greatly curved. Sutural line fairly 

 well marked. Polar capsules round. Dimensions: sutural diameter 10/x, 

 breadth 18 to 20^t, thickness 9/i, diameter of polar capsules 3 to4)u. Sporo- 

 plasm contains two nuclei, 3.5 to 4^i in diameter. 



LEPTOTHECA LONGIPES Auerbach 



[Fig. 11] 



1910 Leptotheca longipes Auerbach 1910b : 771 



1912 Leptotheca longipes Auerbach 1912 : 42-43 



Habitat: Gall-bladder of Brosmius brosme Asc; Bergen (May). 



Vegetative form: Trophozoites elongated or rounded. Only few 

 pseudopodia which are very long. Small forms with a very long process, 

 were observed in large numbers; length of the body being lO/x, while the 

 process was 60// long. Endoplasm contains nuclei of various sizes. Disporous. 



Spore: Form similar to that of Leptotheca informis, though smaller. 

 Dimensions: sutural diameter 8 to 9^, breadth 12 to 14jLt, thickness 8jLt, 

 diameter of polar capsule 2.5ix. 



LEPTOTHECA FUSIFORMIS Davis

Habitat: Gall-bladder of Cestracion zygaena; Beaufort (July).
