Mr. Anderson. Your statement makes it very simple to determine, 

 one group is in shore, and you go out a few miles and the other groap 

 is bevond that. That is not it at all from what I see of the graph. 



Mr. Butler. I meant to suggest that there is some overlap. Per- 

 haps the chairman could describe it. 



Mr. Leggett. Let the record show that Mr. Butler has presented a 

 chart which shows the concentration of Eastern Spinners in the area 

 which appears to be roughly 300 miles off the coast of the tip of Baja, 

 Calif., and traveling, then, generally parallel to El Salvador, Costa 

 Rica, Nicaragua and Panama, and terminating somewhere down near 

 Peru. 



There also appears to be a gray area about the same band which I 

 suspect is a hybridized area with the white belly. 



Mr. Butler. Although I am not completely certain, I think there 

 is an overlap of the populations, but that the populations themselves 

 are largely distinct, and not hybridized. 



There may be some actual crossbreeding of them. I defer to Dr. 

 Fox on that subject. 



Mr. Leggett. All right. 



Mr. Butler. Also on those charts is a map of where the CYRA is, 

 and it is all done in degrees of latitude and longitude. 



Mr. Anderson. Your language was misleading. Was your answer 

 that in shore was 300 miles? 



Mr. Leggett. Approximately. 



Mr. Andersox. Three hundred miles to me is not in shore. It is a 

 long ways out. It is misleading, very misleading. 



Mr. Butler. What I meant was that it was primarily within the 

 CYRA so that when the boats do fish outside the CYRA, as they do 

 for the latter half of the fishing year, beginning in May and for 

 some time in June, outside the CYRA, the porpoises they will be 

 running into are Offshore Spotted and the White Bellied Spinner, 

 as opposed to the Eastern Spinner. 



Mr. Anderson. The way vou read the paragraph, you go out a 

 little way and you have the Eastern Spinner, and you will have to go 

 out a little further and you will hit a White Belly. It is more com- 

 plicated than that. 



Mr. Butler. Yes, it is. I didn't intend to give the impression that 

 it was that simple. 



Nonetheless, the basic truth of my observation remains as illus- 

 trated by the charts. 



I would ask that the charts be included in the record after my 

 testimony. It is an official portion of an official government report. 

 It graphically makes the point that I have been trying to make 

 verballv. 



Mr. Leggett. You want your chart in the record? 



Mr. Butler. I would like the chart in the record. 



Mr. Leggett. The chart is in the record. 



Mr. Rogers. Without objection of the Members. 



Mr. Leggett. By unanimous consent, the chart is in the record. 



Mr. Rogers. Thank you.
