Supraorbital pores have not been reported in other flat- 

 fishes. The supraorbital canal is an extension of a nerve 

 branch arising from between the frontals at the posterior 

 rim of the dorsal orbit. In Lepidopsetta the pores of the 

 canal are supported by a series of I76 bones (Fig. 14), sim- 



ilar in size and shape to the suborbitals. Typically each 

 bone shares in the support of one or two pores. 



Among other North Pacific pleuronectids examined. Par- 

 ophiys vetulus'^ has 6-11 pores and Isopt^etta inolepis 2-12 

 pores, whereas Linuiiida aspera and L. piiinifasciatu^.
