NOTE ON A HERMAPHRODITE COD. 317 



Other examples of hermaphroditism in cod have been described by 

 Howes,* Masterman,-|- Williamson, | etc. 



Masterman gives a tabular list of eleven cases for comparison, 

 including his own observation and those cited by Howes. In all these 

 the ovarian organ preponderates. Great diversity is shown in the 

 position of the testis, which may be single or in as many as three 

 distinct and separately attached parts. In Williamson's two cases, one 

 presents a perfectly symmetrical form with a small testis attached to 

 the anterior end of each ovary, while the other is completely asym- 

 metrical, the right gonad being an ovary and the left a testis, the two 

 uniting in the anal region and having a common genital aperture. 

 My specimen presents a further variation in the position of the testis. 

 In the relatively large size of the testicular portion it is also 

 peculiar.
