It is possible that two species are included here, as suggested by Kyle — a northern 

 form (velivolans), and the true whiff-iagonis from the EngUsh Channel and western 

 coasts. Petersen's descriptions of post-larval specimens rather suggest that this is 

 the case, but the material at my disposal does not enable me to recognise more than 

 one species. L. velivolans is said to have a deeper body and rather fewer fin-rays than 

 L. whiff-iagonis.

 to 3^. Snout as long as or shorter than eye, diameter of which is 3 to 3 J in length of 

 head ; anterior margins of eyes about level. Maxillary extending to below middle of 



^ The exact southerly limit of the range of this species is difficult to ascertain, as some of the 

 records probably refer to L. boscii. According to Vaillant, it occurs off the coast of Morocco and 

 at the Azores. It does not appear to enter the Mediterranean, except on rare occasions.
