434. The generative organs of a Dog with extreme hypospadias. 



The scrotum is bifurcated. There is a large hood-like 

 pouch in front of the imperforate penis, and a median 

 furrow in front of the urethra. The urethra opens close 

 to the anus. The testes are contained in the scrotum. 



Hunterian. 



b. Androgyny. 



435. The generative organs of a small androgynous Dog. The 



testes are abdominal and atrophied. The vasa deferentia 

 are impervious and like fine threads. The penis is im- 

 perforate and very rudimentary. The urinary and sexual 

 outlets are immediately in front of the anus ; they are 

 close together, but distinct. The vasa deferentia are 

 united into a single cord, nearly two inches behind the 

 external orifice *.

436. The generative organs of an androgynous Sheep. The 



penis is imperforate and of small size ; it is retracted in 

 lateral sigmoid curves, so that its extremity lies in front 

 of the urethral outlet. The retractor muscles are well 

 developed; the glans is covered by a hood-like sheath. 

 The extremity of the urethra is marked by a blue glass 

 rod. There are four well-marked teats, each with a 

 single gland-duct. The testes are abdominal.

437. The generative organs of a young androgynous Bull. The 



penis is permanently retracted, so that its extremity lies 

 in a sac-like pouch in front of the anus. Hunterian. 



438. The testes of the same animal, imbedded in a mass of sub- 



cutaneous fat above four well-formed abdominal teats.

439. A section of the pelvis of an androgynous Calf, showing the 



generative organs. 



There is a narrow urine-genital pouch, about 4 inches in length ; 

 it is marked by a blue rod. The urethra, marked by a purple 

 rod, opens into this sinus near its outlet. The upper (anterior) 

 extremity of the sinus ends in two cornua, into which the vasa 

 deferentia open. Two small cysts, probably the remains of the
