DESCRIPTION OF SPECIES. 
Ceratomyxa lata sp. n. (Fig. 1). Host: Capros sanglier. Habitat: Gall 
bladder. Spore: 19/u, x 7/z, crescentic in shape, ends rounded, polar capsules 
large, not marginal. The proportions and shape of this form distinguish it 
from any other, the nearest to it being C. coris Georg, (from Coris julis), which 
is less crescentic in form and from a different host and locality. A similar 
form was found in Pleuronectes microcephalus , and is given provisionally the 
same name.
