spawn was found to be abundant and to pass very readily from the 

 body. On taking two or three of the males the usually smooth portion of 

 the heads was found to be covered with numerous tubercles from one to 

 two millimeters long. The tail flns of the males were also found with 

 rows of similar tubercles along the rays. No tubercles were found on the 

 female. 



The spawn could have done nothing else than to have floated off into 

 the still water of the pool below, where some may have found lodgment 

 among the water plants. 



Whether polyandry, or perhaps more exactly diandry, if the term 

 may be so used, is always the habit of the female sucker I am unable lo 

 say, but in this case it certainly was.
