In these secretions many slender, cylindrical, irregularly bent or curved, rather long (some fragments being about mm. long), in places densely crowded spermozeugmas are embedded. Their struc- tureless, light red axial portion is 18 /jl thick, totally covered by the spermatozoan head-ends which are dark violet, almost black, and form a dense layer of about 6 /i thickness; the entirely pale caudal ends of the spermatozoa project freely into the mass of secretions.
