Dorsal prostates. — The tubules of the dorsal prostates (Fig. 71) although

also similar; perhaps because the narrower tubules contain less secretion, 

 the formation of fissures is rare. The gland has several ducts in which the 

 mucous membrane, in contrast to the ducts of the coagulating gland, is free 

 from folds.
