series of flattened superposed naked spores, which are successively 

 separated from the protoplasmic mass below. Apex opening 

 irregularly beside the large terminal spine, which seldom persists. 

 Total length 100-150 X 10-13 ju. Sporogonium 50-60X10-12 ju. 



On the terminal claws of the legs of Diopsis sp., nos. 2716, 2717, Kamerun, 

 West Africa. 



This type is most nearly allied to Thaxteriola, from which it differs in being 

 4-celled, the sporogonium having no differentiated efferent neck, and dis- 

 charging broad flat spores. A majority of the individuals examined are 

 comparatively young, and only a few are beginning to form spores, so that in 

 this instance it is also impossible to say whether sporulation is a continuous 

 process or ceases after all the primary contents has been used. 



Laboulbeniopsis, nov. gen. — Axis simple, consisting of a dif- 

 ferentiated foot, a 2-celled stalk, and a well defined terminal 



sporogonium, at the

the rest of the cavity being filled with numerous minute hyalin

 Termitarius, nov. si 



■Foot and 



sporogonium pale brownish, the stalk nearly hyaline. Foot large, 

 externally strongly convex, a portion of its flat insertion deeply 

 blackened, more or less pointed below; the stalk much narrower, 

 its upper cell shorter and broader than the lower. Sporogonium 

 as long as or longer than the stalk, straight, subsymmetrical, 

 slightly inflated below, tapering distally to the rather broad, 



terminal pore, which 



occupying the 



fourth or less of the cavity, lying side by si 



than the other. Total length 100-130 /x ; sporogonium 45-50 X 1 2 \x ; 



stalk X8-io/x; foot 25X12/Z; spores 3. 5-4X2. 5/x.

This form occurs very rarely, associated with Coreomycetopsis, of which 

 it was at first believed to be a stage or condition. The two, however, do not 

 seem to be related, although their general appearance is so similar. There is 

 not sufficient material available to determine the complete history of its 

 sporulation. As far as can be determined from the material available, the 

 spores develop simultaneously, filling the whole cavity of the sporogonium 

 above its two basal cells, and there is no evidence in the specimens examined 

 that successive periods of spore-formation occur, after the first are discharged.
