to fat-body of host. Mycelium like that of C. Indiana is very fragile and 

 extremely thin-walled. Formation of sporangium similar to C. Indiana. 

 Early sporangium with dense protoplasm, globular or oval, measuring 

 19 X 28-23 x 37 [x. Vacuolated sporangium 20 x 30-24 x 40 (x, oval, 

 or with one side flat and the other side convex. The next stage of 

 sporangium with a thick refractile wall and dense contents and large 

 number of nuclei. Mature sporangium asymmetrical, circular in shape, 

 with one side flat and the other side strongly convex; thickness of spo- 

 rangium less than breadth. Size 28 x 34-40 x 44 u.. Thickness 16-23 u.. 

 Wall of sporangium with many raised ribs running in concentric or 

 eccentric circles, the middle ribs branched and irregular .... When view- 

 ed at the edge, the sporangium is somewhat oval with ribs running 

 parallel to each other. 



"Structure of sporangial wall similar to C. indiana and composed 

 of alternating light and dark striae. Inner spore-wall of C. stegomyiae 

 absent. Thickness of wall at the rib 2.6-3.4 u., and between the ribs 1 .3 

 (j." (Iyengar, he. cit.). 



In larvae of the following species of Anopheles: A. subpictus, A. 

 vagus, A. annularis, and A. varuna, India.

"Hyphae 4-12 jx thick, elongated, branched and anastomosing, 

 rather sparse and poorly developed, frequently encased in a thick trans- 

 parent sheath; hyphal bodies spherical, oval or pyriform; enlarging to 

 an irregularly oval body, 27-35 X 30-55 [x, the protoplasm becoming 

 differentiated into an inner, dense, oval, granular zone and an outer, 

 wide hyaline zone; inner granular part 12-31 x 29-35 [x, outer zone 

 4-12 ;x wide; the resting sporangia developing from these bodies; 

 resting sporangia oval in outline, 21-30 X 29-45 u., with a very dis- 

 tinctive wall. The inner wall is smooth, hyaline and 1.5-2.5 [x thick; 

 the outer wall pale brown or yellow and 2-3 fj. thick, extending out to 

 form seven or eight longitudinal, anastomosing, steep ridges, about 

 4-5 jx tall and spaced 7-9 jx apart; wall between ridges with very fine 

 transverse striations and entire sporangium covered with remains of
