■SS3] Jeffries oti a?/. Hermaphrodite Bird. lO 



The supra-renal bodies (3, Fig. i) were of fair size for an adult 

 bird, and were wedged in between the heads of the kidneys and 

 the aorta. 



The ovary (6, Fig. i and Fig. 2) was entirely normal in position 

 and appearance, and presented the usual resemblance to a bunch 

 of grapes. It measured about .31:; by .24 of an inch, the ova 

 varying from .07 of an inch down. In all there were about forty 

 ova easil}' visible to the eye. These, as shown by the inicroscope, 

 were perfectly normal, and were ftdly as large as the ova of 

 females of the species shot at the same time. The ovary was 

 hung from the body, directly below the head of the left kidney, 

 by the usual peritoneal foulds, and also separated by a median 

 fould, the mesentery, from the right side. 



The oviduct, normal in appearance and position, was but 

 slightly convolute and not dilated. So sexual action had not fully 

 commenced. 



No vas deferens was to be found on the left side. 



The testicle (3, Fig. i and Fig. 3), much shrunken on account 

 of its maceration and sudden plunge into alcohol, was the least 

 preserved part of the whole body. It was in its usual position 

 on the right side, and was perfectly distinct from either the kid- 

 ney or suprarenal bodv. Through the outer tunic a few con- 

 volutions could be seen. 



The vas deferens extended from the testicle back in front of the 

 right kidney and outside the pelves to the middle part of the right 

 ureter. Here it crossed and became internal, but recrossed and 

 again became external before reaching the cloaca. Near the kid- 

 nev it was good sized, but shortly tapered down to a thread in 

 very close connection with the wall of the ureter. The vas def- 

 erens was perfectly normal in structure for a bird before rut, but 

 abnormal in relation to the right ureter. 



There was no trace of an oviduct on the right side. 



Since almost all the cases of reported lateral hermaphroditism 

 have been, at one time or another, explained away as abnormal 

 growths, or remains of the Wolffian bodies, I deemed it best to 

 subject the testicle to a microscopic examination. The tunica 

 albuginea, though by no means thick, was quite strong and com- 

 posed of connective tissue. From its inner surface hung a few 

 small threads, probably vessels and' trabeculae. The tunic was 

 pierced at the vertebral surface by the vas deferens, vessels and
