In the following columns I contrast the main characters of unripe and ripe reproductive organs of the male, which proved useful to me in differentiating them. Unripe Testes white. Vas deferens, portion between testis and seminal vesicle, dirty white in colour. Seminal vesicle small. Accessory glands short and thin, only slightly developed. Ripe Testes yellowish. Vas deferens, portion between testis and seminal vesicle, yellowish in colour. Seminal vesicle swollen.
