[25] REVIEW OF THE SCLENIDA. 367 
On the Carolina coast it has received the very inappropriate name of 
“Sea Trout.” 
Specimens of the typical regalis are in the museum at Cambridge from 
various localities on the Atlantic coast, and from Mobile and “ Florida 
Keys,” on the Gulf coast. Its occurrence in the Gulf must be infrequeyt, 
as no specimens have been obtained by Dr. Jordan at Galveston, New 
Orleans, Pensacola, Cedar Keys, or Key West. 
The form called Otolithus thalassinus by Holbrook has not been ree- 
ognized by later collectors, and it has usually been considered identical 
with C. regalis. . 
A specimen lately sent to us by Mr. Silas Stearns from Pensacola 
seems to answer to Holbrook’s description, and we have found two simi- 
lar specimens in. the museum at Cambridge, one (No. 438, M. C. Z.) 
from Pass Christian, Mississippi, the other from Hampton Roads, Vir- 
ginia. The only differential characters which we have noted are given 
in the analysis of species. As C. regalis is subject to considerable vari- 
ation, we have regarded C. thalassinus as an extreme form or variety 
rather than as a distinct species. It may, perhaps, be found to inhabit 
a different depth of water than that which the common Weak-fish fre- 
quents. 
The following is a description of our specimen from Pensacola: Depth, 
43 in length; head, 63; D. X—I, 24; A. IT, 11; lateral line, 56; length, 
12 inches. 
Body compressed ; not especially elevated; of about the same depth 
everywhere betwen the ventrals and the vent; caudal peduncle rather 
long and stout. 
Head pointed, subconical; profile straight, scarcely descending; eye 
rather large, 12 in snout, 5$ in head; mouth large, oblique; premaxil- 
lary anteriorly on a level with the upper margin of the pupil; maxillary 
extending beyond the pupil; lower jaw strongly projecting, its tip en- 
tering the profile. 
Teeth of the lower jaw in two series, anteriorly in a single series; those 
in front small and subequal; the inner ones recurved ; those of the side 
much larger. Teeth of the upper jaw in two series; those of the outer 
series scarcely decreasing in size towards the angle; those of the inner 
series becoming minute on the sides; canines moderate, 4 the diameter 
of the eye. 
Preopercle with a striated and dentated dermal margin; gill-rakers 
slender; those near the angle half the length of the eye. 
Lower pharyngeals weak and long, grooved below; teeth at the angle 
several times as large as the rest, all more or less recurved ; the ante- 
rior ones specially so; teeth of the upper pharyngeals unequal. 
First dorsal spine inserted above the end of the first fourth of the 
ventrals; the spines slender; the third highest, reaching to the ninth 
spine, 22 in head; second anal spine about twice as Jarge as the first, 
22 in length of eye; anal rays 22 in head; pectorals broken; ventrals
