5U06 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
but which not unlikely came from the East Indies. Nemipterus mae- 
ronemus agrees very closely with Nemipterus nematophorus Giinther, 
from Sumatra. According to Bleeker the chief differences are these, 
that in macronemus but one dorsal spine is filamentous, in nematophorus 
two; in macronemus the fins are more pointed. All these are doubtful 
characters and it is probable that Nemipterus macronemus came from 
Sumatra rather than from Surinam. 
Subfamily VI.—SPARINZ. 
XXII. STENOTOMUS. 
Stenotomus Gill, Canadian Naturalist, August, 1865 (argyrops). 
Type: Sparus argyrops Linneus = Sparus chrysops Linneus. 
Ktymology: otevds, narrow; topzds, cutting; from the narrow incisors. 
This genus contains, so far as known, three species, all American; 
one lives in rather deep water and differs considerably from the others. 
The genus is close to Calamus, from which the flattened incisors mainly 
distinguish it. 
ANALYSIS OF SPECIES*OF STENOTOMUS. 
a. First dorsal spine as long as eye, the second about as long as third, which is about 
2in head; temporal crest obsolete; frontal bones not gibbous or porous; an- 
trorse spine attached to the fourth interneural by a downward projecting 
spur about twice as long as the spine. 
b. Body elongate-ovate, the depth gradually decreasing from first dorsal spine to 
caudal peduncle; anterior profile not steep, nape slightly convex, a slight de- 
pression above and behind eye, convex over snout; pectoral about as long as 
head, 3} in body; scaly sheath at base of soft dorsal and anal inconspicuous; 
sneut long and pointed, 2 in head; eye large, less than width of preorbital, 
about 3% in head; interorbital area very convex; six strong conical teeth in 
front of upper jaw and eight in lower; molar teeth coarser and larger than 
in S. chrysops; scales on cheek reaching to top of eye, the upper rows less 
distinct than the lower, the anterior row of about 20 scales; caudal fin mod- 
erately forked, the middle ray about 24 in longest ray. Color nearly plain dull- 
silvery, with golden longitudinal streaks following the rows of scales; axil 
dusky; ventrals dark. Head, 3; depth, 2}; D. x11, 12; A. x11, 11; scales,

bb. Body ovate-elliptical, the depth about the same from the first dorsal spine to 
the eleventh; anterior profile steep, nape convex, a strong depression above 
and in front of eye, straightish over snout; pectoral less than head, about 34 in 
body; a Scaly sheath very conspicuous at base of soft dorsal and anal fins; 
temporal crest obsolete; supraoccipital crest continuous with the frontal ~ 
bones; snout short, 24 in head; eye small, narrower than the preorbital, about 
41 in head; incisor teeth very narrow, almost conical; molars in two rows 
above; scales on cheek extending above the upper margin of eye, the anterior 
row composed of about 20 scales; caudal fin forked, the middle ray about 4 in 
longest ray. Color brownish, somewhat silvery below, everywhere with bright 
reflections, but without distinct markings in the adult; soft parts of vertical 
fins mottled with dark in adult; young faintly barred; axil dusky. Head, 3}; 
depth, 27; D. x11, 12; A. 111, 11; scales, 8-50-16............--CHRYSOPS, 95.
