56 Ovaries of the Gar, Lepidosteus 



the diameter is 1.2 mm. In C20, there was the greatest varia- 

 tion. A few ova were as small as 0.8 mm., while others were as 

 much as 2.2 mm. in diameter. 2 mm. is the average diameter 

 of the adult egg. In one very large fish, No. 42a, the total weight 

 of the ovaries was estimated at 500 or 600 gm. These were the 

 most mature in appearance of any collected. This ovary had a 

 lower water content, the highest protein content, and a much 

 higher amount of total fats. Broadly speaking, the protein 

 except in the very young remains comparatively constant. The 

 organic extractives are also constant. The total lipoids tend to 

 increase and the total water to decrease with development of 

 the gar ovaries. 

 We were not successful in securing ripe ova for analysis.
