FISHERY BULLETIN: VOL. 73, NO. 1 



egg has an average diameter of 1.08 to 1.20 mm, 

 and contains a single, yellowish oil globule 

 averaging 0.28 to 0.32 mm in diameter. A dis- 

 tinctive pigment pattern forms on the embryo 

 after the blastopore closes. The eyes remain un- 

 pigmented through hatching. 



Pigmentation on the larvae undergoes consider- 

 able change during the yolk-sac stage. Newly 

 hatched larvae have scattered melanophores on 

 the dorsal and lateral surfaces of the head and 

 trunk and on the oil globule. By the time the 

 yolk is used up, pigment coalesces onto the dorsal 

 and ventral surfaces of the trunk, above the brain 

 and gut, and forms in the eyes. Teeth are present 

 in 192-h-old larvae, at a size of 4.0 mm standard 

 length. 



ACKNOWLEDGMENT 



I thank Michael Fahay for illustrating the 

 eggs and larvae shown in this paper.
