902 THE AMERICAN NATURALIST. [VoL. XXXV. 
The sexual organs were not in an active state; a large corpus 
adiposum is present, and behind it a small elongate but not dis- 
tended genital organ, which upon examination proved to be an 
ovary containing numerous slightly developed but recognizable 
eggs. I did not find any evidence to show whether the animal 
had ever laid eggs or was still immature, but the latter suppo- 
sition seemed more likely.
