vertical, entire, inconspicuously striate. Gill-rakers -14, very long, 1^ 

 in orbit. 



First dorsal spine short, the spines thence increasing to the fourth, 

 which is 2^0 times in head; longest soft ray equals length of snout and 

 eye. Caudal double-truncate, 1^ in head. Base of anal fin rather less 

 than diameter of eye, the second spine strong, about one- third head, and 

 two-thirds the longest anal ray. Pectorals as long as head, not quite 

 reaching vertical from vent. Yentrals, 1^ in head. 



Series of scales run nearly to tips of all the vertical fins, except spi- 

 nous dorsal; ventrals likewise scaly. 



88. Cynoscion maculatum (Mitch.) GiU.— Salmon Trout. 



An abundant food-fish, caught with seines in muddy channels in the 

 harbor. 



89. Cynoscion regale (Bl. Sclin.) Gill.— Trowf; Shad-Trout. 

 Less abundant than the preceding. 



90. Cynoscion nothum Holbrook. — Bastard Trout. 



Caught mostly outside the harbor, where it can be found at all sea- 

 sons, though most abundant in summer. It is never so abundant as the 

 other species of the genus, and though occasionally reaching a length 

 of 3 feet, the specimens caught are mosOy of small size; the largest 

 seen by us was about 12 inches long. It is universally known to the 

 fishermen as "bastard trout," the belief prevailing that being unspotted 

 and still evidently a "trout," it must be a cross between maculatum 

 or regale, and some silvery species, as the "whiting." 



Color in life, grayish-silvery above, and on sides to lower level of pec- 

 torals; then abruptly silvery; upper parts thickly punctulate with 

 darker; inconspicuous dark streaks follow the rows of scales above, 

 formed by the darker centers of the scales. Snout and tip of lower jaw- 

 blackish; mouth white within. Anal and ventrals white, other fins 

 dusky. 



Head 3^ to 3§ in length; depth, 4. D. IX, I, 29; A. I, 9. Scales, 58 

 (oblique series or pores) ; 70 vertical series. L. 8 inches. 



Body well compressed; lower jaw distinctly projecting; maxillary 

 2^ in head, reaching sUghtly beyond pupil ; teeth in lower jaw anteri- 

 orly small, in a very narrow band ; laterally enlarged and in a single 

 series; upper jaw with a very narrow band in front and on sides, the 

 outer row enlarged ; one or two long, slender canines in front. A deep 

 pit on each side of vomer. 



Eye large, longer than snout, or than interorbital width, 4 in head. 

 Preopercle very broad, the angle much produced backwards, the thin 

 membranaceous portion with conspicuous radiarting striae. Opercle 

 terminating in two very long, slender spines, the membrane continued 

 beyond them. Gill-rakers long and strong, f in number, the longest 

 one-half orbit.
