THE CYPRINODONTS. 77 



the ovary, and the disiiosition of their openings, above the shutter, are indi- 

 cated, from a dextral female, on Plate VII. Fig. 14. Valenciennes' state- 

 ment, " Quant a la femelle, ses ovaires sont doubles ; mais le gauche est 

 beaucoup plus gros que le droit ; celui-la ne depasse pas cependant la portion 

 elargie du foie," no doubt was correct for the individual he had in hand. It 

 is incorrect as a general description. In different females the ovaries vary 

 greatly : in some cases one side is the larger, in other specimens it is the 

 other side, and occasionally the ovary appears to be single. Fig. 5 of Plate 

 VIL was taken from a female in which both sides of the ovary were well 

 developed, the right half being a trifle the larger, while Fig. 4 of the 

 same plate represents a specimen in which the right side of the ovary 

 apparently is so enormously enlarged as to nearly fill the entire abdominal 

 chamber without any indication of a left side or of a doubled ovary. In this 

 individual the intestines were empty and crowded far forward, while the liver 

 was greatly reduced in size, indications that before capture the usual feed- 

 ing habits had been suspended for a time. An intestinal fold, seen in Fig. 

 5 of Plate VII, in front of the middle of the ovary, is bisected in Fig. 16 of 

 the same plate. Each kidney and each testis pours its secretions into its 

 proper receptacle by a distinct canal ; the openings into the chambers are 

 separate.
