^Asterisk indicates inclusion of dorsal fin pterygiophores in body deptti measurement 



caudal count of 19 rays was observed on a 6.0-nim 

 SL postflexion specimen. 



Dorsal and anal fin bases are forming in the 

 finfold on larvae 4.3 mm NL, and the full comple- 



ment of rays develops by 6.0 mm SL. Pelvic fin 

 buds are evident during early caudal formation 

 but rays are first observed on a 6.0-mm specimen. 

 Pectoral rays were fully formed on a 10.0-mm
