specimen.) 



United States and the northern Bahamas (figs. 13, 

 14, and 19). The three body proportions of these 

 specimens, seven K. sectatrix and four K. incisor, 

 expressed as percentage of standard length, 

 showed the following: the head lengths of K. 

 sectatrix were more than 27 percent, while those of 

 K. incisor were less than 27.5 percent; the body 

 depths at pelvic fin of K. sectatrix were 41 percent 

 or more, while those of K. incisor were 41 percent 

 or less; and the pectoral fin lengths of K. sectatrix 

 were above 18 percent, while those of K. incisor 

 were less than 18 percent (table 13). 



There was Httle or no indication, at any size, of 

 interspecific variation in the distances from snout 

 to dorsal, anal, pectoral, and pelvic fins (figs. 15, 

 16, 17, and 18).
