 ventral margin just posterior to the vent. 



and larval pigment, especially in the form of melanophores 

 present laterally and along the dorsal and ventral margins, is 

 useful in identification of some genera (Figs. 193, 195-200). 

 Melanophores, concentrated on spatulate swellings in elongated 



dorsal and pelvic rays help to distinguish larval lampriforms 

 although care should be taken since elongate, sometimes pig- 

 mented appendages are found in the larvae of a number of 

 unrelated taxa (Govoni et al., 1984). Among these taxa, how-
