Parasitology, 13:226, figs. 1-7. 1921 



Mycelium scanty in the body cavity, well developed around the vis- 

 cera, anterior intestinal coeca, and beneath the hypoderm; branched, 

 the branches 2-6 jx in diameter, irregular with terminal swellings 30-35 [i. 

 long by 20-22 \i in diameter which fragment from the mycelium and 

 become hyphal bodies free in the visceral fluid where they increase to 

 32-65 [j. in length; resting spores formed from the hyphal bodies, oval, 

 flattened on one side, 37.5 by 20 fx-57 by 30 jjl, inner wall smooth, 0.7 jj. 

 thick, outer wall 1.7-2 (jl thick, yellowish with minute pores and a fine 

 line of dehiscence from pole to pole on the convex side, germination 

 not observed.

 scutellaris), coll. Lamborn, Federated Malay States. 



Keilin rightly conjectured that the resting spores of this species rup- 

 ture along the fine line of cleavage and probably give rise to flagellated 

 spores. Since he was dealing with preserved material he could not ascer- 

 tain this stage. 



A second type of resting spore with thinner walls than in the majority 

 was associated with those of Coelomomyces stegomyiae. They may possi-
