rocephalus . This character can be useful in a size 

 range O13.0 mm SL) which may be troublesome 

 when pigment patterns are no longer helpful and 

 adult characters (e.g., barbel length, mouth and 

 anus position, or shape of fins) are not fully de- 

 veloped. Larvae >20.0 mm SL may also be dis- 

 tinguished by a combination of meristic counts 

 (Table 1).

NOAA: Beverly Vinter who provided great assis- 

 tance in the interpretation of distinguishing 

 characteristics in gadid larvae and illustrated the 

 larvae and caudal fin; Bernie Goiney and Jay 

 Clark for technical assistance; and Arthur Ken- 

 dall for helpful discussions. 



April G. Maclean, formerly OSU, assembled a 

 large portion of the M. proximus series and made 

 some of the counts and measurements. Joanne 

 L. Laroche (OSU) helped gather additional 

 specimens from OSU collections.
