the gape anteriorly being about at the level of the middle of the eye and the maxillary 
reaches to middle of pupil. The notochord is curved slightly upward distally, and 
rather definite rays (caudal fin) are present below the curved portion. The bases 
of the soft dorsal and the anal fins are rather definitely shown by the thickening of 
the tissues, though no rays are present. The pectoral fin membranes remain rather 
prominent as in smaller specimens, but no ventrals are evident. The black lateral 
stripe already present at a length of 2.5 millimeters, has become more prominent, 
and it extends from the shoulder nearly to the base of the primitive caudal fin, which 
(as already stated) is situated under the ventral side of the distal part of the notochord. 
The stripe is rather more continuous than in smaller specimens, but the dashes of 
which it is composed still are visible in some specimens. Furthermore, the line has 
slight vertical projections, making its edges somewhat ragged. The line extends 
forward faintly across the opercle and on the snout. Both the upper and lower lips 
are dusky. More or less black is present over the abdominal mass, which probably 
is subsurface. The dark markings along the ventral outline of the tail, distinct in 
the smallest specimens at hand, remain, and are nearly uniform in size. A few very 
small and indefinite dark points are evident on the ventral surface of the head and 
trunk (fig. 36). 
Figure 36 . — Cynoscion nebu'.osus. From a specimen 3.2 millimeters long. 
This species, at the length described, is distinguished from C. regalis principally 
by the black lateral line, which C. regalis does not possess. The first-mentioned 
species also has much more numerous black markings along the ventral outline of the 
tail, none of which are especially enlarged, whereas in C. regalis the spot lying at the 
posterior end of the base of the primitive anal is considerably larger than the others. 
C. nebulosus, at the size described, appears to be somewhat more slender, the greatest 
depth being contained 3.4 to 3.6 in length, compared with about 2.7 to 3.0 in C. regalis. 
Insufficient specimens are available, however, to determine definitely the relationship 
in this respect. 
Specimen 7 millimeters long. — The body is quite elongate, compressed, and shapely 
for such a small fish. The dorsal profile anteriorly ascends rather gently and is 
moderately convex. The vent is situated much nearer the base of the caudal than 
the tip of the snout (preanal distance 1.6 times in standard length; postanal distance 
to base of caudal, 2.6 times), and the greatest depth is contained 3.3 times in the 
standard length. The snout is rather pointed and longer than the eye. The mouth 
is large, less strongly oblique than in smaller specimens; the gape anteriorly is almost 
on a level with the lower margin of the pupil ; and the maxillary reaches about to the 
vertical from the posterior margin of the pupil. Although the caudal fin is well 
developed and apparently rather sharply rounded (the rays are broken in part 
and the exact shape cannot be determined), the upward curved tip of the notochord
