PROF, G. B. HOWES ON SOl^rE 



specimeBS examined by Prof. Max Weber and myself. In no 

 case was either the length or condition of the fish whence the 

 organs were obtained known ; but, except for a fatty degenera- 

 tion undergone by the testis in the example numbered III., the 

 animals appear to have been, in every case, healthy and pro- 

 ductive of normal sexual elements.

Left ovary. Right ovary. 



17-5 I 16-5 



Testis present at posterior end of each ovary ; 

 confluence established on each side, by means of a 

 short duct entering posterior pointed extremity of 

 ovary. 



12 I 16 



Testis present on right side only; confluence as 

 with I. 



17 I 13 



Testis (in bulk as large as the two ovaries 

 together) on left side only ; confluence over a wide 

 area of the venti'al postero-external border. Sub- 

 stance of testis largely fatty and degenerate ; 

 spermatozoa looked for but not observed. 



19 I 20-5 



Testis on middle left side , confluence estab- 

 lished over a wide area of postero-external border. 

 Jvlotile spermatozoa abundant. 



12 I 12 



Testis on right side ; confluence as for I., II., by 

 well-defined duct. 



12 I 12 



Testis on right side ; confluence established by a 

 short duct, at anterior extremity of ovary. 



10-5. I 10-0
