gut in preflexion larvae is visibly short, but elongates during 

 flexion and post-flexion. 



Benthodesmus (Fig. 320).— Gorbunova (1982) described B. 



Evseenko (1982b) described a 20.3 mm SL specimen. Pigmen- 

 tation in these larvae is strikingly similar to Lepidopus caudalus 

 larvae described by Padoa (1956a). However, in B. elongatus 

 simonyi the first dorsal fin spine is not more elongate than the 



elongatus simonyi from a size series of 5 larvae 3.5-1 8 mm and other spines as in Lepidopus and Trichiurus (Fig. 320). Bely-
