Oda: Egg and larval development of Paralichthys cahfomicus and Xystreurys liolepis 



397 



in the ventral finfold towards the end of the stage (Fig. 

 7E). Pigment is present on the elongate dorsal fin rays 

 of flexion larvae and in the medial finfolds and fin 

 anlagen in an area between about one-half and three- 

 quarters the distance from snout to tail tip. Melano- 

 phores are also found at the anteriormost portion of 

 the anal-fin anlage (Fig. 8A). Postflexion larvae are 

 pigmented on the elongate dorsal fin rays, between 

 about the 30th and 50th dorsal elements, and along 

 most of the length of the medial fin bases. Melano- 



phores are also present on the first few rays and near 

 the midpoint of the anal fin (Fig. 8C). 



Yolksac larvae are heavily pigmented at the tail tip 

 with a few other melanophores found on the head and 

 body (Figs. 7A, B). Scattered rows of dorsolateral and 

 ventrolateral pigment form on the trunk and tail in the 

 preflexion stage, but pigment along the dorsal and 

 ventral margins does not form continuous double rows 

 (one on either side of the margin) until late in the 

 preflexion stage (Figs. 7D,E). Heavy dorsal midline
