14-4-millimeter stage . — Total length, 14.4; standard length, 12.9.; length to vent, 
7.5; length of head, 3.45; snout, 0.9; diameter of eye, 0.8; greatest depth before vent, 
2.5; depth behind vent, 2.0 millimeters. Myomeres, 22 to vent plus 18 behind. 
About 12 very tiny spines of first dorsal apparent, 15 elements and 13 partly formed 
rays of second dorsal rays; anal I, 8, incomplete; caudal rays developed, distal end of 
caudal emarginate ; ventrals budding. 
Pigmentation. — -The marking is much as in preceding stages, but the chromato- 
phores are inclined to be lighter with the ventral series less conspicuous or entirely 
lacking. 
20.0-millimeter stage . — Total length, 20.0; standard length, 17.0; length to vent, 
10.5 ; length of head, 4.7 ; snout, 1.0 ; diameter of eye, 1.55 ; greatest depth before vent, 
3.95; depth behind vent, 3.2; length to first dorsal, 6.1; to second dorsal, 10.3; to anal, 
1 1.0 millimeters. Myomeres, 24 to vent plus 16 + behind. At this length the young 
fish resembles the adult with all fins formed, serrated preopercle, and large mouth. 
Dorsal XV, II, 13; anal II, 8. 
Pigmentation. — This specimen is sparingly marked, with chromatophores limited 
to a few large stellate ones on jaws and over head, a few at dorsal and anal bases, and 
others distributed over sides of tail from vent backward, extending somewhat on to 
caudal. The anterior half of body from behind head to region of vent is almost color- 
less. 
For comparison with the previous stage described the following heavily pigmented 
specimen is included. It is in a slightly older stage of development evidenced by 
the longer snout, larger mouth, and more advanced fins, although barely larger than 
the other. 
Postlarva, 20. 5 -millimeter stage . — Dorsal III to VII-II, 9 to 12 (badly mutilated); 
anal II, 6 to 8; caudal shallowly forked; ventrals developed, below pectorals. Total 
length, 20.5; standard length, 17.25; length to vent, 10.5; length to first dorsal, 5.95; 
length of maxillary, 2.0; greatest depth, 3.6; diameter of eye, 1.5 millimeters. Myo-
