摘要:

SUMMARY1The testes are permanently abdominal in position and there is no scrotum. The testes are globular. The caput and cauda epididymidis are similar in shape and size. The vasa deferentia open into the collecting tubules of the seminal vesicles.2The seminal vesicles are large glandular bodies, divisible into an anterior glandular portion and a posterior ductus portion. The paired ducts open into the muscular urethra on the summit of a crista urethrae.3The prostate is a compact glandular mass, lying outside the muscular urethra below the neck of the bladder. It completely surrounds the muscular urethra only in the breeding season; at other times it is incomplete along the dorsal side. Its ducts are numerous, and open into the muscular urethra independently near the crista urethrae.4The muscular urethra is a simple muscular tube between the bladder and the penis. The genital ducts open into it.5The urethral gland which surrounds the muscular urethra is minute and is covered by the muscle of the urethra. The numerous short ducts of the urethral gland open into the muscular urethra.6A utriculus prostaticus is absent.7Cowper's glands are large and lie in the region of the muscular urethra into which they open by a pair of short ducts.8The penis is large, pendulous conical and directed caudally. It is divisible into three regions.The glans is large and complicated in structure. Its surface is covered by numerous minute denticles. There is a deep gutter projecting into the substance from its distal dorsal side. There are three lips, one ventral and two dorso‐lateral, at the tip.The corpora cavernosa together are horse‐shoe shaped in section and enclosed in a common sheath; but internally the two are separated by the septum. The corpus spongiosum is simple and surrounds the penile urethra up to the external orifice. An accessory corpus cavenosum is absent.The os‐penis is a simple cartilaginous curved plate, pointed terminally. It is restricted to the distal half of the glans.The penile urethra presents a pair of blind diverticula at its distal end.9The whole genital system shows a marked enlargement in size during breeding s
