(A) Unhatched prolarvae of Sebastes jlavidus collected Feb. 1986. 

 Pigmentation of retina is apparent, as are well-formed somites, 

 63 X . (B) Tangential section of unhatched prolarvae with completed 

 pigmentation of the retina. Tail continues to lengthen and is seen 

 to pass the head slightly, 63 x . (C) Newly-hatched larva ofS-Jknidus 

 showing close association of liver with oil vacuole, developing jaw 

 and well-developed gut, 40 x . (D) Cross-section of a recently-spent 

 ovary oiS. jlavidus collected March 1986. Many empty and collapsed 

 follicles are being resorbed, 40 x . (E) Recovering and early develop- 

 ing ovary collected April 1986 showing reorganization of ovarian 

 stroma as resorption nears completion, 63 x . 



Eyed-larvae Retinal pigmentation began as a black 

 deposit outlining the periphery of the retina. Concur- 

 rently, somites were well formed in the thoracic and 

 tail regions (Fig. 4A). Mature embryos (prehatching 

 larvae) exhibited complete pigmentation of the eyes and 

 a well-developed musculature system along the entire 

 length of the tail (Fig. 4B). Embryos in this broad 

 developmental category were in field samples collected 

 in January and February. Had ovaries containing
