FISHES OP NEW YORK 19 



large, the length of its opening being contained twice in the 

 hight of fourth gill opening. The oblong eye is placed near the 

 dorsal profile; the length of the orbit is about one half the 

 greatest hight of second dorsal; the length of the eye equals 

 about one fourth width of mouth. The length of upper jaw is 

 slightly more than that of lower, and nearly equals the distance 

 between the spiracles. The distance from the mouth to the 

 nostril is about one fourth least hight of tail; the distance 

 between nostrils equals four times the distance from eye to 

 spiracle. The interorbital space equals one half the length of 

 second dorsal base. The distance between the spiracles equals 

 four times their greatest length. 



The first dorsal is very long and low, highest behind its mid- 

 dle, the length of its base equal to seven times its greatest 

 hight ; its distance from the snout is a little more than twice the 

 greatest length of pectoral. The second dorsal is distant from 

 the end of the first a length equal to nearly twice its greatest 

 hight; the length of its base is somewhat more than the body 

 hight at origin of first dorsal. The second dorsal begins at a 

 distance from the end of the first, which is equal to the hight 

 of body at ventral origin; the length of its base equals twice the 

 interorbital distance ; its hight equals nearly twice the length of 

 the orbit. The anal is entirely under the second dorsal, but its 

 base is a little less than five sevenths as long as that of the 

 latter; the greatest hight of the anal equals the least hight of 

 caudal peduncle. 



The caudal originates at a distance from the end of the second 

 dorsal about equal to the hight of the anal; it is divided by a 

 notch into a short upper portion, whose length is very little 

 more than the greatest hight of first dorsal, and a very low and 

 long lower portion, the longest margin of which is nearly twice 

 as long as the snout. The distance of the caudal from the end 

 of anal base equals one fourth the length of second dorsal base. 



The distance of pectoral from snout is contained five times in 

 total length; the length of pectoral equals nearly twice the width 

 of its base, and is a little more than one ninth of total length.
