Diagrams illustrating the origin and develop- ment of the multiple testis of Desmognathus, up to a four-lobed stage. See Tables I. and II. for average lengths of animals having testes of these types. The cephalic end of the testis is at the right in all these figures. Solid black represents regions occupied by primary or secondary sperma- togonia. Unshaded areas are those occupied by later stages of the germ cells—spermatocytes I. to mature spermatozoa. Cross-hatched areas are. Ple
