spines represented by 2 soft rays (Table 3). At 

 5.4 mm the anteriormost soft ray became a spine. 

 All specimens s=7.5 mm had X, 14 dorsal fin 

 spines and rays. The second dorsal spine was the 

 longest ray in the dorsal fin in specimens 4.0-12.4 

 mm. In the 22.4 mm specimen, all dorsal fin rays 

 except the first spine were about equal in length 

 (Figure 2C). Serrations did not appear on the 

 dorsal spines of L. campechanus between 4.0 and 

 22.4 mm. 



Pelvic Fin 



The smallest larva had not yet developed pelvic 

 fin soft rays but had developed the pelvic spine 

 (Figure lA). The pelvic spine was smooth on the 

 anterior margin on 4.0 and 4.7 mm specimens. 

 Between 4.7 and 4.8 mm this spine developed —30 

 fine serrations along its anterior margin. All lar- 

 vae and juveniles 4.8-12.4 mm had these serra- 

 tions. The number of serrations generally in-
