the head, the depth and the diameter of the eye, and the position of the hinder 
edge of the maxillary in relation to the eye. 
In a specimen 4.1 cm. long from Pivers Island, Beaufort, N. C., taken July 22, 
1913 (fig. 16), the ground color of the body is light, tinged with yellowish above 
and with a silvery sheen below the lateral line. An interrupted lateral stripe of 
brownish pigment, slightly narrower than the eye, extends along the middle of the 
side; on the opercle and caudal fin the pigment is darker, almost black; a broken 
stripe of similar -color extends along each side of the median line of the back from 
tip of snout to base of caudal, with interspaces between the broken portions widest 
below; the tip of the lower jaw is brownsh; the first dorsal fin is dusky, the second 
translucent, with a narrow median stripe of brown; the blackish area on the caudal 
is triangular, its apex near the tip of fin; the anal and paired fin s are translucent. 
A specimen 2.8 cm. long, taken at Beaufort, N. C., July 15, 1913 (fig. 15), agrees 
closely in form and coloration with the preceding, except that the lateral stripe is 
continuous and proportionately wider and that portion on the caudal is black. 
In a specimen 5.8 cm. long (fig. 17), taken with the first, the form and color pattern 
is similar except that the stripes are slightly more diffuse and less interrupted and 
the markings on the caudal more broken and of a lighter shade and that two dark 
narrow stripes appear on the second dorsal. 
In these examples the body is deeper than in the adult, about 3.75 in standard 
length; the head proportionately longer, about 3 in standard length; the eye 
larger, 4.25 to 4.75 in head; the maxillary shorter, 2 in head, its hinder edge reaching 
to hinder edge of pupil; the caudal pointed, its median rays longest; the gill rakers, 
4 + 8, shorter and stouter than in Cynoscion regalis. 
Five specimens of Cynoscion nehulosus, 11 to 12.5 cm. long, taken in Chesapeake 
Bay in December, 1915, represent various stages in transition to color of adult. 
In an example 11 cm. long ( Fish Hawk, station 8381, II miles SSE. of Smith Point 
Lighthouse off the mouth of the Potomac River, in 25 fathoms, taken December 5, 
1915, fig. 18), the ground color above the lateral line is yellowish, tinged with silver, 
below the lateral line silvery white; the stripes are darker, almost black, and more 
broken than in smaller examples, their broken portions tending to form irregular 
blotches, which later develop into round black spots; the lateral stripe is absent 
from the caudal, and the fin is blotched with dusky spots. In an example 11.2 cm. 
long from same station the spots are slightly more distinct, the lateral stripe being 
broken up with two rows of roundish blotches one above the other, below the lateral 
line; the dorsal stripe is beginning to show a similar separation into blotches. 
In an example 12 cm. long (from Fish Hawk, station 8366, one-half mile W. by S. 
of Thimble Shoal Lighthouse in 14 fathoms) the spots are more distinct and have 
encroached on the portion of the side that formerly separated the stripes (fig. 19). 
In form these specimens are more slender, the depth being about 4 in standard 
length; the eye is smaller, 5 in head; the maxillary is 2.2 in head, extending nearly 
to the hinder edge of the orbit; and the median lobe of the caudal is shorter. 
In an example 24 cm. long the round black spots are confined to that portion of 
the back behind the middle of the first dorsal and above the lateral line, with a few 
exceptions on the middle of the side, to the second dorsal and caudal fins. The 
spots are about the size of the pupil or smaller; on the second dorsal they are in
