A SIGNIFICANT CASE OF HERMAPHRODITISM IN FISH. 213 



cross banding, when compared with the average condition seen 

 in an adult female (Fig. 4), will show a striking contrast. It 

 will be noted that the hermaphrodite exhibits a somewhat juve- 

 nile figure in that the head is shorter, the body broader and the 

 tail less tapering. These points might not be patent to one not 

 very familiar with the species.

Fig. 4. Wash drawing, showing a typical female F. majalis. Many specimens 

 show a far more complete transformation of the juvenile cross-banded pattern into the 

 series of longitudinal stripes but few females of this size show a less advanced con- 

 dition. Note the long head, comparatively small dorsal and anal fins, and compar- 

 atively light ground color of head and back. 



General Considerations. 

 I. The extreme rarity of hermaphroditism in fish normally 

 unisexual makes this case worthy of note, especially as the sexes 

 are so well differentiated in form, color pattern, and behavior. 

 No other case comparable with this is on record. There seems, 

 in fact to be only one case of abnormal hermaphroditism in fish 

 in the available literature. This is a brief description by South- 

 well (,'02), of a hermaphrodite gland taken from a smoked her-
