hatching. . SCIAENA SATURNA (and other 
species of Sciaenidae ?) 
; . tt. Chromatophores appearing when the 
: gastrula covers about two-thirds of the 
yolk, proliferated from the embryo only; 
more chromatophores on tail at the time 
ofhatching.. HypsopsErra GUTTULATA. 
_ aaa. The eggs are hatched in a brood-pouch along the ventral surface of the 
ee SYNGNATHIDAE, 
UNIDENTIFIED EGGS. 
Species No. 1. Plate x, figs. 6-9. 
_ One egg of this species was dredged August 14, at 9:15 a, m., in the 
‘Stage represented by fig. 6, Pi. The egg is transparent, the globule 
_ amber-colored. The ess measures 0.80 millimeter, the oil globule 0.12 
_Inillimeter. The pigment cells were minute and the difference between 
yellow and black not well marked. 
_ Four hours later the tail is just beginning to develop. The oil glob- 
ule is very sparingly pigmented; the yolk sack in the neighborhood of 
- the globule is covered with many yellow and one or two black cells. 
The color cells on the embryo are very small and ntunerous, the black 
"ones aS usual are on the dorsal, the yellow ones on the ventral surface 
of the embryo.
