TUCKER: LARVAL DEVELOPMENT OF C1THARICHTHYS AND ETROPUS 



Table 7.— Measurements (mm) of larvae and juveniles of Citharichthys sptiopterus. ECF = 

 early caudal formation, Late = late flexion, Post = postflexion. S = symmetrical, 1 = to one- 

 third of the way to the dorsal ridge, 2 = one-third to two-thirds of the way to the dorsal ridge, 

 3 = two-thirds to all the way to the dorsal ridge, R = on the dorsal ridge, T = transformed. 



'Measurement does not include dorsal or anal pteryglophores. 



Fin and Axial Skeleton Formation 



Caudal skeleton development apparently is 

 similar to that of C. cornutus. Size ranges of 

 available larval specimens in each stage are as 



follows: Early caudal formation, 3.7 mm NL; late 

 flexion, 5.7-6.8 mm NL; postflexion, 9.0-10.6 mm 

 SL. All caudal rays are calcified by 5.7 mm. 



All precaudal neural spines, the first 13 caudal 

 neural spines, the first 13 hemal spines, and no
